Types of compounds bases

02 Acid, bases and salt

A base is a chemical substance which can neutralise an acid.
They are capable of accepting protons and/or contain completely or partially displaceable OH⁻
So, it dissolves in water to produce hydroxide ions (OH- ions in solution).
For example, for example, baking soda, milk of magnesia, calcium hydroxide, Ammonium hydroxide (NH₄OH) or ammonia water, Magnesium hydroxide (Mg(OH)₂ ) or milk of magnesia. Etc.
Bases turn red litmus to blue.

Some bases are soluble in water while others are not. A base which is soluble in water is called an alkali.

The general properties of bases are:
Bases have bitter taste
Bases feel soapy to touch
They are good conductors of electricity in the aqueous state.
They have pH greater than 7.
For example, if we rub a drop of sodium hydroxide solution between the tips of our fingers, they will soon begin to feel soapy (or slippery) as if we have applied to them.
When hydroxide solution is heated with zinc, then sodium zincate and hydrogen gas are formed:

REACTION OF BASES WITH ACIDS TO FORM SALT AND WATER

Reaction of base with acid results in the formation of salt and water.
For example, when sodium hydroxide reacts with the sulphuric acid, then sodium sulphate and water are formed:

Non - metal oxide + Base \to Salt + Water

In the following reaction calcium hydroxide is a base and carbon dioxide is a non-metal oxide. And they react to produce calcium carbonate and water:

A base is a substance which dissolves in water to produce hydroxide ions ( ions) in solution.
A common property of all the bases or alkalis is that they produce hydroxide ion (ions) when dissolved in water.

Sodium hydroxide is used in the manufacture of soap, paper and a synthetic fibre called ‘rayon’.
Calcium hydroxide also known by the name slaked lime is used in the manufacture of bleaching powder.
Magnesium hydroxide is used as an ‘antacid’ to neutralise excess acid in the stomach and cure indigestion.
Sodium carbonate is used as washing soda and for softening hard water.
Sodium hydrogen carbonate is used as baking soda in cooking food, for making baking powders, as an antacid to cure indigestion and in soda-acid fire extinguishers.
