Preparing Salts of Potassium, Sodium and Ammonium

Preparing Salts of Potassium, Sodium and Ammonium

  1. Potassium, sodium and ammonium salts are usually prepared through the reactions of acids with alkalis.
  2. Reaction acid with alkali will produce salt and water.
    Acid + Alkali → Salt + Water
  3. The salt is prepared by titration method of acid and alkali using an indicator.

Steps to Prepare the Salts of Potassium, Sodium and Ammonium through Titration

Step 1 – Titration to Find the End Point

  1. The end point is the point in a titration at which the 2 reactants have completely reacted.
  2. An endpoint is often marked by a color change.

Step 2 – Titrate Without Indicator

  1. The product obtain in step 1 is contaminate by the indicator.
  2. The reaction is repeated by using the same amount of reactants as in step 1, without using any indicator.
Step 3 – Crystalisation

Step 4 – Filtration and Drying
