How does a base work in chemistry?
base, in chemistry, any substance that in water solution is slippery to the touch, tastes bitter, changes the colour of indicators (e.g., turns red litmus paper blue), reacts with acids to form salts, and promotes certain chemical reactions (base catalysis).
Do bases feel painful?
They are highly corrosive to the skin and eyes. Strong bases are insidious in that even a concentrated solution often causes no pain until the corrosive damage is severe.
How do acids and bases work?
The chemical difference between acids and bases is that acids produce hydrogen ions and bases accept hydrogen ions. A base is a substance that neutralises acids. When bases are added to water, they split to form hydroxide ions, written as OH-. We call a base that has been added to water an alkaline solution.
What makes a base a base?
A base is also defined as a molecule that has the ability to accept an electron pair bond by entering another atom's valence shell through its possession of one electron pair. There are a limited number of elements that have atoms with the ability to provide a molecule with basic properties.
Do bases smell?
Usually no smell (except NH3!)

How do you explain acid and base to a child?
Ask the kids to name some common substances and guess if they are acidic or basic. You can mention that acidic substances, like orange juice or tomatoes, taste sour. Bases, like baking soda or soap, are bitter. This is also a good time to explain that some acids and bases are very strong and can be harmful.
What is a base in science?
(bays) In chemistry, a substance that can accept hydrogen ions in water and can neutralize an acid. Bases feel soapy or slippery on the skin and they can turn certain dyes blue. An example of a base is sodium hydroxide. Basicity is measured on a scale called the pH scale.
What do bases release?
Bases are substances that react with and neutralise acids, producing water. When dissolved, bases release hydroxide ions, OH-(aq) into solution. Water is the product of an acid and base reacting.
What are the 3 main properties of a base?

Bases are another group of compounds that can be identified by their common properties. A base tastes bitter, feels slippery, and turns red litmus paper blue. The properties of bases are often described as the “opposite” of acids.
What hurts more acid or base?
Burns from alkalis tend to be much worse than burns from acids. The one exception to this rule is hydrofluoric acid. This strong acid also creates liquefaction necrosis and is considered one of the most dangerous acids.
What do bases typically feel like?
A "base" is defined as a molecule in an aqueous solution that can accept protons or donate electrons. Bases are usually bitter to taste, slippery to touch, and have a pH greater than 7 on the pH scale.
What feeling do bases have?
Bases usually feel slippery, like soap. Salts are neutral compounds, which means they have no charge, and they are the result of an acid-base neutralization reaction where acids and bases react to yield water and a salt. NaCl is the type of salt that you use to season your food.

How to do an overload resolution on check?
Start with the sizeof (check (Host<B,D> (), int ())) part. The compiler can quickly see that this check (...) is a function call expression, so it needs to do overload resolution on check. There are two candidate overloads available, template <typename T> yes check (D*, T); and no check (B*, int);. If the first is chosen, you get sizeof (yes), else sizeof (no)
Why is the private bit ignored?
The private bit is completely ignored by is_base_of because overload resolution occurs before accessibility checks.
What is the meaning of "back up"?
Making statements based on opinion; back them up with references or personal experience.
What would happen if the host was not const?
Following on your second question, note that if it weren't for const, Host would be ill-formed if instantiated with B == D. But is_base_of is designed such that each class is a base of itself, hence one of conversion operators must be const.
Does B prevent a check from taking place?
The same applies here, the fact that B is a private base does not prevent the check from taking place , it would only prevent the conversion, but we never ask for the actual conversion ;)
Is D* more specialized than B*?
It possibly has something to do with partial ordering w.r.t. overload resolution. D * is more specialized than B* in case D derives from B.

How many characters are in base64?
Base64 encoding works with a 65-character subset of the US-ASCII charset. The first 64 characters out of the 65-character subset are mapped to an equivalent 6-bit binary sequence ( 2 6 = 64 ). The extra 65th character ( =) is used for padding.
How many bits are in the last chunk of input?
The last chunk of input contains exactly 16 bits: Two zero bits are added to form three 6-bit groups. Each of the three 6-bit groups is converted to the corresponding Base64 alphabet. Finally a single pad ( =) character is appended to the output.
What happens to the organic compound when the mineral base is removed?
The mineral base will remove the proton, leaving the original organic compound. The organic compound is uncharged and not as soluble in water anymore. It will go back into the ether layer.
How do you add a proton to a mixture?
There is also a basic one, which reacts with acids by picking up a proton. In this case, a proton might be added via reaction with a strong mineral acid (represented by HX in the drawing). Suppose an aqueous solution of mineral acid, such as HCl, were shaken vigorously with an ethereal solution of an organic base and an organic neutral. The proton would be transferred to a basic compound, but not to a neutral one. The basic compound would become ionic, and more water-soluble.
How to separate organic compounds from each other?
Acid-base extraction is typically used to separate organic compounds from each other based on their acid-base properties. The method rests on the assumption that most organic compounds are more soluble in organic solvents than they are in water. However, if the organic compound is rendered ionic, it becomes more soluble in water than in the organic solvent. These compounds can easily be made into ions either by adding a proton (an H + ion), making the compound into a positive ion, or by removing a proton, making the compound into a negative ion.
What is the group of carboxylic acids?
The carboxylic acid group contains a C=O (a carbonyl) with an additional OH group attached to the carbon. Examples are shown below.
Why is nitrogen a lone pair?
The lone pair is needed in order to make a bond with the proton. Once the lone pair has donated to the proton to form a bond with it, the nitrogen compound becomes positively charged. It then becomes more water-soluble. If the nitrogen does not have a lone pair, it is unable to bond to a proton.
Why is water on the bottom of the ether?
The water is on the bottom in this case because water has a higher density than ether, so it will sink to the bottom (along with anything dissolved in it).
What is a strong acid?
Sometimes, the term, "strong acid", designates a compound that completely ionizes in solution, so that it automatically gives up a H+ ion and forms an ionic compound. Hydrochloric acid, HCl, in water is a good example.
