Can ferric chloride still be used after absorbing water?
Thread Content
Our factory purchased bags of ferric chloride and recently found that some of the ferric chloride agglomerated after absorbing water. I would like to ask if the agglomerated ferric chloride can still be used as a salt. Please let me know. If it cannot be used, can you tell me why? Thank you.

The agglomerated ferric chloride can be used as a salt. This is because the properties of the agglomerated ferric chloride have not changed, and the ferric ions still exist in the form of ferric ions. The reason why ferric chloride is used as a flocculant is not that ferric chloride has a flocculating effect, but that ferric ions generate iron hydroxide colloid under alkaline conditions, and the iron hydroxide colloid has a flocculating effect. The iron hydroxide increases the flocculation of magnesium hydroxide.
