why nh4cl is acidic in nature?
As mentioned in the other answer, NH4Cl is an “acidic” salt, formed by the neutralization of a strong acid (HCl) with a weak base (NH3). Therefore, when the salt is completely dissociated in an aqueous solution, it forms NH4+ and Cl- ions. Explanation: ... The solution of Ammonium Chloride is therefore acidic.
