Question: are amines soluble in hcl?
Answer: Are all amines soluble in HCl? Dear Student, Yes because, When HCl ( acid) is added to amines ( base) it forms ammonium ion (ammonium salt). It's a acid base reaction. RNH2 + HCl → RNH3+ + Cl- As salts dissolve in water readily Therefore the solubility of amine in water increases with addition of HCl.
