Conclusion About The Differences Between Acids And Bases
Acids are corrosive, while bases are not. Acids can be used to clean things like rust off metal or remove paint from wood.
How to tell the difference between acid, base and salt?
We can also see the difference between acid, base and salt by conducting the chemical experiment. We must have learned the basic experiment in the school laboratory about litmus paper. This is the tool to determine the properties of substance. This paper can also check whether the substance acid or base. If it’s acid, it will turn the blue litmus paper to the red color.
Which has a lower pH, acid or base?
Acid has the lower pH, while base has the higher pH. The value of acid pH is less than 7, while the base pH values is greater than 7. pH value of 7 is the neutral pH value. We can understand that the higher level of positive hydrogen ions in the solution, pH will become less.
What is an acid in water?
We basically define acid as a substance which releases the ion of H + when it dissolves in the water. Acid contains the hydrogen element, like hydrochloric in HCL, nitric in HNO3, Sulphuric in H2S04 and so on. However, we also take a note that not all compounds having the hydrogen are acid. The example is H2O or water and CH4 or Methane. Here’re some popular examples of acid reaction when they dissolve in the water solution
How does salt form?
There’s also another form of chemical reaction between acid and base to create salt. Salt can be produced by the reaction between the metal and acid. When metal dissolves in the acid solution, it will create the salt with hydrogen. The example of this reaction is as follow: H 2 SO 4 + Mg -> MgSO 4 + H 2.
What happens when you react salt with another metal?
Salt also has special reaction with the metal. If we react the metal with the salt of another metal, it will produce the salt of first metal and second metal. Its reaction can be described below:
What is the common form of base?
While acid gives the H + ion, base releases OH – the ion in the aqueous solution. The common form of base is metal hydroxide. The popular examples of base compound are Natrium Hydroxide (NaOH), Calcium Hydroxide (Ca (OH) 2) and many more. Here’s an examples of base reaction when it dissolves i the aqueous solution:
What are the two types of acids?
There’re two types of acids consisting of organic and inorganic acid. The examples of inorganic acids are Nitric acid, sulphuric acid, hydrochloric acid. While the example of organic acid is the vinegar. The chemical formula of vinegar is CH 3 CO 2 H.
What is the difference between Acid and Base?
Substances that transfer a hydrogen ion (H+) to another chemical are known as acids whereas a substance that produces a hydroxide ion (OH-), when dissolved in water is referred to as a base.
Conclusion
After reading this article you learned a lot about the differences between acid and base. They are no longer able to confuse you.
