Faces: 13. Explain why a solution containing both NH3 and NH4Cl is less basic than a solution
containing only NH3 of the same concentration.​

In a solution containing ammonia solution and ammonium chloride, ammonia hydrolyses in water to produce hydroxyl ions.

NH3 +H2O → NH4+ + OH-

Ammonium chloride ionises in the solution to produce ammonium ions and chloride ions where the ammonium ions undergo hydrolysis to produce more ammonia solution.

with this one i know the answer in craters one reason i looked it up and i learned about it there is my evidence
