What is the error that occur in the titration?
May 25, 2011 · Titration » Titration errors. There are several types of errors that can make titration result differ from the reality. First, there is an intrinsic error of the method - end point is not identical with equivalence point and color changes of indicators are not instant. Reasons of this difference are discussed in details in the end point detection and acid-base titration end point …
What is systematic error in titration?
Titration is the slow addition of one solution of a known concentration (called a titrant) to a known volume of another solution of unknown concentration until the reaction reaches neutralization, which is often indicated by a color change. The solution called the titrant must satisfy the necessary requirements to be a primary or secondary standard.
What is titration error How can it be Minimised?
What are the two types of titration errors?
How do you calculate titration error?
- Subtract one value from the other: 2.68 - 2.70 = -0.02.
- Depending on what you need, you may discard any negative sign (take the absolute value): 0.02. This is the error.
- Divide the error by the true value:0.02/2.70 = 0.0074074.
- Multiply this value by 100% to obtain the percent error:

What is titration in chemical analysis?
Titration is a sensitive analytical method that lets you determine an unknown concentration of a chemical in solution by introducing a known concentration of another chemical. Several factors can cause errors in titration findings, including misreading volumes, mistaken concentration values or faulty technique.
What causes errors in titration?
Several factors can cause errors in titration findings, including misreading volumes, mistaken concentration values or faulty technique. Care must be taken as the solution of the known concentration is introduced into a specific volume of the unknown through laboratory glassware such as a burette or pipette.
What is the end point of a titration?
The end point of a titration is when the reaction between the two solutions has stopped. Indicators, which change color to indicate when the reaction has stopped, do not change instantly. In the case of acid-base titration, the indicator may first lighten in color before changing completely.
How to misread burette?
But markings on a burette can be easily misread. One way to misread the volume is by looking at the measurement on an angle. From above, it can seem like the volume is lower, while from below, the apparent volume looks higher. Another source of measurement error is looking at the wrong spot.
What is the function of the bottom of a concave curve?
A solution forms a concave curve and the bottom of the curve is used to measure the volume. If the reading is taken from the higher sections of the curve, the volume measurement will be in error. Concentrations. Errors in concentrations directly affect the measurement accuracy.
What are the types of errors that can make a titration result differ from the reality?
There are several types of errors that can make titration result differ from the reality. First, there is an intrinsic error of the method - end point is not identical with equivalence point and color changes of indicators are not instant. Reasons of this difference are discussed in details in the end point detection and acid-base titration end ...
Can a burette leak before titration?
Leaking burette - sometimes burettes leak slowly enough to allow titration, but will loose several tenths of milliliter if left for several minutes after titrant level has been set to zero and before titration started.
Can random errors be adjusted?
Finally, there are thousands of possible random errors, that can't be adjusted for. Some of them are typical human errors, that can be limited by sticking to lab procedures, but as long as there is a human operator involved, they will be never completely eliminated. Some of possible cases are:
Can dirty glass be wet?
Also, dirty glass is not properly wetted by the solutions and they can form droplets on the glass surface (see volumetric glassware cleaning section for a picture) making exact volume measuring impossible.
Can you forget to rinse glassware?
It is also not uncommon to forget to rinse walls of the glassware after solution was transferred - it may happen both to solution pipetted to some vessel, or to titrant that formed droplet on the flask wall and was not rinsed with distilled water.
Why do some reactions need correct temperature range?
Some reactions need correct temperature range to keep stoichiometry (avoid side reactions). Losing solution - too vigorous swirling can end in liquid splashing from the titration flask before the end point had been reached. It may also happen that some titrant lands on the table instead of inside the flask.
What is NaOH used for?
They are usually related to chemical characteristics of titrant and other substances involved - NaOH used as a titrant tends to adsorb atmospheric CO 2, KMnO 4 and thiosulfate slowly decompose and so on. These will be addressed on individual titration procedure pages.
What is the purpose of titration?
In a broad sense, titration is a technique to determine the concentration of an unknown solution.
What is a titration reaction?
A titration is a controlled chemical reaction between two different solutions. A weak polyprotic acid is an acid that is usually considered as weak acid in its monoprotic form (only one H + in the molecule), but instead has more than one H+ in the molecule, therefore making it a polyprotic acid.
What is the name of the process of adding a solution of a known concentration to a known volume of answer
No headers. Titration is the slow addition of one solution of a known concentration (called a titrant) to a known volume of another solution of unknown concentration until the reaction reaches neutralization, which is often indicated by a color change.

Titration is the slow addition of one solution of a known concentration (called a titrant) to a known volume of another solution of unknown concentration until the reaction reaches neutralization, which is often indicated by a color change.
What is titration in chemistry?
Titration is the process in which one solution is added to another solution such that it reacts under conditions in which the added volume may be accurately measured. It is used in quantitative analytical chemistry to determine an unknown concentration of an identified analyte.
What is titration in chemical reactions?
Titrations are most commonly associated with acid-base reactions, but they may involve other types of reactions as well. Titration is also known as titrimetry or volumetric analysis. The chemical of unknown concentration is called the analyte or titrand.
What is the standard solution of a reagent of known concentration called?
A standard solution of a reagent of known concentration is called the titrant or titrator. The volume of titrant that is reacted (usually to produce a color change) is called the titration volume.
What is the name of the flask that is used to titrate an analyte?
A typical titration is set up with an Erlenmeyer flask or beaker containing a precisely known volume of analyte (unknown concentration) and a color-change indicator. A pipette or burette containing a known concentration of titrant is placed above the flask or beaker of an analyte.
Where is the pipette placed?
A pipette or burette containing a known concentration of titrant is placed above the flask or beaker of an analyte. The starting volume of the pipette or burette is recorded.
What is a burette in analyte?
A pipette or burette containing a known concentration of titrant is placed above the flask or beaker of an analyte. The starting volume of the pipette or burette is recorded. Titrant is dripped into the analyte and indicator solution until the reaction between titrant and analyte is complete, causing a color change (the endpoint).
What is a titration reaction?
A titration is a technique where a solution of known concentration is used to determine the concentration of an unknown solution. Typically, the titrant (the know solution) is added from a buret to a known quantity of the analyte (the unknown solution) until the reaction is complete.

What is the purpose of knowing the volume of titrant added?
Knowing the volume of titrant added allows the determination of the concentration of the unknown. Often, an indicator is used to usually signal the end of the reaction, the endpoint.
