I looked for this answer online and I keep coming across conflicting equations:
I want to know the equation showing the dissociation of NH4Cl in water.

I would also like to know what the hydrolysis equation for the ion dissociated in water would be for this salt.

NH4Cl(aq) + H2O ===> NH4OH + H+ + Cl-

NH4OH is a slightly dissociated compound. The NH4+ and OH- ions aren't readily available. So H+ and Cl- availability mean that the salt gives acidic aqueous solutions. In simpler language, NH4Cl is the salt of a strong acid and a weak base, so its salts give acidic solutions.

NH4+(aq)  +  H2O(l)  Leftwards Arrow----->  NH3(aq)  +  OH-(aq) (I think NH3 is better than NH4OH, but ....)
No hydrolysis for chloride ion since HCl is a strong acid.

NH4Cl is an acidic salt.
