Solubility of phthalimide in water
Web(iii) Methylamine in water reacts with ferric chloride to precipitate hydrated ferric oxide. Due to the + I effect of − C H 3 group, methylamine is more basic than water. Therefore, in water, methylamine produces O H − ions by accepting H + ions from water. O H − ions react with ferric chloride to precipitate hydrated ferric oxide.
