Concept explainers
(a)
Interpretation:
The chemical equation is to be determined showing
Concept introduction:
An acid can be defined as chemical species which release protons or hydrogen ion or accept electron/s. The acidity of chemical species depends on the concentration of hydrogen ion that is higher the concentration of hydrogen ion, higher the acidity of chemical species.
(b)
Interpretation:
The chemical equation showing basisity of
Concept introduction:
The base can be defined as the chemical species which releases hydroxide ion in aqueous solution and accept protons. In this case also, the higher hydroxide concentration results in higher alkalinity.
