Answer:
11) Solubility is the maximum amount of a substance that will dissolve in a given amount of solvent at a specific temperature. There are 2 factors that affect solubility temperature and pressure
12) The laws state that (1) the amount of chemical change produced by current at an electrode-electrolyte boundary is proportional to the quantity of electricity used and (2) the amounts of chemical changes produced by the same quantity of electricity in different substances are proportional to their equivalent weights.
13) Salt is an ionic compound that has a cation other than H+ and an anion other than OH– and is obtained along with water in the neutralization reaction between acids and bases. Eg:- NaCl, CuCl2 etc. Sodium chloride is one of the best-known salt.
14)A chemical bond always has a pair of electrons that have opposite spins. ... A covalent bond is formed when both atoms share their electrons. But a coordination bond is formed when one atom donates one of its extra electron pairs to another atom.
