Question

Complete and balance these equation (if necessary):

(i) NaOH(aq) + NH4Cl(s) =

(ii) OH-(aq) + NH4+(aq) =

Answer 1

NH₄Cl(s) → NH₄⁺(aq) + Cl⁻(aq)

(1) NaOH + NH₄Cl → NaCl + NH₃ + H₂O

Na⁺ + OH⁻ + NH₄⁺ + Cl⁻ → Na⁺ + Cl⁻ + NH₃ + H₂O

(2) OH⁻(aq) + NH₄⁺(aq) → NH₃(g) + H₂O(l)

Answer 2

In this case, the NH4Cl is specified as a solid.

Its important to note that, as Im not convinced it can be written other than

Na+ (aq) + OH-(aq) NH4Cl(s) ----> NaCl(s) + NH3(g) + H2O(l)

which would serve as your ionic/net equation.

your molecular would be

NaOH(aq) + NH4Cl(s) ---> NaCl(s) + NH3(g) + H2O(l)

am curious what the higher ups have to say regarding this one! ;-)
