State four desirable properties of a gravimetric precipitate.

Short Answer

Expert verified

The Four desirable properties of gravimetric precipitate

  1. Easy filterability
  2. Insolubility
  3. High purity
  4. Stable and constant composition

Step by step solution

01

Definition

It is an analytical technique that uses a precipitation reaction to separate ions from a solution. The chemical that is added to cause the precipitation is called the precipitant or precipitating agent

02

 Step 2: Desirable properties of gravimetric precipitate

  1. Easy filterability - Particles should be smaller considering the size
  2. Insolubility 鈥� needed in order to get high yield of precipitate
  3. High purity 鈥� less impurities need to be present in sample
  4. Stable and constant composition - necessary in order to obtain accurate weight.
