Differences between alkalis, bases and acids? (answer for many points :) )

Chemistry
1 answer:
Rudik [331]3 years ago

Explanation:

protons.

An acid can also be thought of as a chemical that can neutralize a base. Similarly, a base can neutralize an acid.

Acids turn litmus paper red, while bases make litmus paper turn blue.

Some examples of acids are sulfuric acid, hydrochloric acid, nitric acid, and so on. Some examples of bases are sodium hydroxide, potassium hydroxide, and so on.

Acids generally taste sour, while bases have a bitter taste.

Alkalis are the bases that are water-soluble, which means that they dissolve in water. In other words, not all bases are water-soluble, and only the water-soluble bases are known as alkalis. An example of an alkali is sodium hydroxide. It is a base because it can neutralize an acid, and because it is water-soluble, it is an alkali. An example of a base that is not alkali is copper oxide. This chemical can neutralize an acid, but it is insoluble in water.

In other words, all alkali are bases but not all bases are alkalis.

Also, an alkali has a hydroxide group, while a base has an oxide group in it.

The volume of a gas at STP is 7.30 L. What is the quantity of gas in this sample?
sladkih [1.3K]

0.326 moles of gas

Explanation:

Knowing the volume of a gas at standard temperature and pressure (STP) we may calculate the number of moles of the gas using the following formula:

number of moles = volume / 22.4 (L /mole)

number of moles of gas = 7.3 (L) / 22.4 (L /mole)

number of moles of gas = 0.326 moles
