Why is lead hydroxide not preferred as an alkali for the preparation of ammonia?
Lead hydroxide is not preferred as an alkali for the preparation of ammonia because it is a toxic substance and poses serious health hazards. Additionally, lead hydroxide can react with ammonia to form toxic lead compounds, further complicating the process. It is safer and more efficient to use other alkalis such as sodium or potassium hydroxide for this purpose.

Compare and contrast the preparation of a salt from an alkali and a base?
Bases are substances that react with acids and neutralize them. They are usually metal oxides, metal hydroxides, metal carbonates or metal hydrogen carbonates. Many bases are insoluble - they do not dissolve in water.If a base does dissolve in water, we call it an alkali.
