Answer to Question #107442 in General Chemistry for Kyonnie Bell

Question

Chemical equation, full ionic equation, and net ionic equation for: NH4Cl and H2O, CH3COONa and H2O, NaHSO4 and H2O

Answer 1

$NH_4Cl + H_2O → HCl + NH_4OH$

$The \ dissociation\ chemical\ reaction \ is:\\ NH_4Cl(solid) = NH_4^+(aqueous) + Cl^-(aqueous).\\ NH_4^+(aqueous) +H_2O(liquid) = NH_3(aqueous) +H_3O^+(aqueous) \\H_3O^+ +OH^- = 2H_2O$

$CH_3COONa + H_2O = CH_3COOH + NaOH$

Sodium acetate, when dissolved in water, undergoes hydrolysis. Salt hydrolysis occurs when a salt of a weak acid or weak base (or both) is dissolved in water. Water spontaneously ionizes into hydroxide anions and hydrogen cations. Sodium acetate dissociates in water into sodium and acetate ions.

$CH_3COONa +H_2O->(Na^+)+(CH_3COO^-) +H^+ + OH^-$

$NaHSO_4 + H_2O → NaOH + H_2SO_4$

$NaHSO4 → Na^+ + HSO4^- \\ HSO_4^- + H_2O → H_3O^+ + SO_4^{2-}$
