Why is NH4OH ...

Question

Why is NH4OH a weak base when it has more concentration of H ions than OH ions?

Open in App

Solution

NH₄OH is a weak base because it is partially ionised in water and produce a small amount of hydroxide ions (OH^- ions)
NH₄OH (aq) $\overset{w a t e r}{\to}$ NH₄⁺ + OH^-

It does not act as acids because NH₄⁺is stable in water. It does not dissociate in water to give H⁺ ions.
