Preparation and Standardization of 0.1 M Potassium Hydroxide

Preparation of Solution

• Dissolve about 6 g of potassium hydroxide in the sufficient carbon dioxide free water to produce 1000 ml.
• Standardize the solution in the following manner.

Standardization of Solution

• Titrate 20.0 ml of the solution with 0.1 M hydrochloric acid using 0.5 ml of phenolphthalein solution as indicator.
• 1 ml of 0.1 M hydrochloric acid is equivalent to 0.005611 g of KOH.
