Answer 1

Hope it helps you

Common Name Chemical Name Formula

salt sodium chloride NaCl

salt substitute potassium chloride KCl

saltpeter potassium nitrate KNO3

slaked lime calcium hydroxide Ca(OH)2

salt any chemical compound formed from the reaction of an acid with a base, with all or part of the hydrogen of the acid replaced by a metal or other cation.

Hydrated salt: A compound with one or more chemically combined water molecule. Example: Copper sulphate pentahydrate (CuSO4.5H2O) Anhydrous salt: A compound in which all water molecules are removed is called Anhydrous salt.

One of the most common examples is CuSO4.5H2O, or copper(II) sulfate pentahydrate. It’s blue in colour.

Another example is Glauber’s salt, or sodium sulfate decahydrate. It’s formula is Na2SO4.10H2O. It occurs as white or colourless crystals.

Answer 2

The names and formulae of two salts are sodium chloride, NaCl, and ammonium chloride, NH4Cl, respectively. Sodium chloride salt (NaCl) is formed from an acid, hydrochloric acid (HCl), and a base (NaOH). Ammonium chloride (NH4Cl) is formed from an acid, hydrochloric acid (HCl), and a base, ammonium hydroxide (NH4OH) .
