Hydrogen cyanide, sometimes called prussic acid, is a chemical compound with the chemical formula HCN. C. The equilibrium constant for the dissociation of HCN (aq) is much smaller than that for the dissociation of HCl (aq). The equilibrium constant for the equilibrium, CN-+ CH 3 COOH ⇋ HCN + CH 3 COO- would be (a) 3.0 x 10-5 (b) 3.0 x 10-4 (c) 3.0 x 10 4 (d) 3.0 x 10 5 In this case, the water molecule acts as an acid and adds a proton to the base. When an uncharged weak acid is added to water, a homogeneous equilibrium forms in which aqueous acid molecules, HA(aq), react with liquid water to form aqueous hydronium ions and aqueous anions, A-(aq). Balancing chemical equations. Write the acid dissociation equation: HCl H + (aq) + Cl-(aq) Because hydrochloric acid, HCl(aq), is a strong monoprotic acid, the value for its acid dissociation constant, K a, would be extremely large. 36,921 results Chemistry.
