Question

The pH value of NH4Cl will be

Answer 1

It is nearly 4.6 to 6.0 Since, NH4Cl is a salt and it is formed from weak base NH4OH and strong acid HCl (via neutralization reaction)

NH4OH +HCl —-> NH4Cl

Now, since HCl is a strong acid it will dissociate completely as well as rapidly and gives H+ n Cl-

And NH4OH is a weak base, it will dissociate slowly.

So, at a particular time, H+ in the solution will be more as compared to NH4+ n OH-. Thus, solution will be acidic at that particular time.


If it is helpful so plz follow me
And plzzz mark it as brainliest
Becoz i need that

Answer 2

4.6. to 6....A salt formed from reaction of a weak base and a strong acid should give an acidic solution. For example, NH4Cl is formed from the reaction of NH3, a weak base, and HCl, a strong acid. The chloride ion will not hydrolyze.
