A major factor considered in selecting a suitable method for preparing a simple salt is its

  1. A.crystalline form
  2. B.melting point
  3. C.reactivity with dilute acids
  4. D.solubility in water.

Answer: D (solubility in water.)

Explanation

Soluble salts are made by neutralisation or acid reactions and crystallisation; insoluble salts by precipitation. So solubility decides the method.
