In an attempt to prepare ferric hydroxide sol by adding small amount of ferric chloride to water, one person got a precipitate of ferric hydroxide. How can you help him to convert `Fe(OH)_3` precipitate to `Fe(OH)_3` sol?

Text Solution

Verified by Experts

The correct Answer is:
By adding ferric chloride solution to the ferric hydroxide precipitate, sol of `Fe(OH)_3` will be obtained.
