1st question answer

In chemistry, pH is a scale used to specify the acidity or basicity of an aqueous solution. Lower pH values correspond to more acidic solutions, while higher values correspond to solutions that are more basic or alkaline. At room temperature, pure water is neutral and has a pH of 7.

Explanation:

2nd question answer

In a chemical reaction, chemical equilibrium is the state in which both reactants and products are present in concentrations which have no further tendency to change with time, so that there is no observable change in the properties of the system.

3rd question ans Characteristics of chemical equilibrium - definition

At a given temperature, the measurable properties like pressure, concentration, density or colour remain constant in chemical equilibrium.

Chemical equilibrium can be attained from either side (forward and backward reactions).
