A salt consists of two parts known as radicals. The positively charged part of a salt (Cation), which has been derived from a base, is known as a basic radical.
The negatively charged part of the salt (anion), which has been derived from an acid, is known as an acidic radical.
Due to the high dielectric constant of water, the force of attraction holding the two ions in a salt decreases; thus, the two ions separate.
Ferrous salts are usually light green.
Bluish green or green.
It is the process by which a salt directly changes into a gaseous phase without melting.
