View the step-by-step solution to: 1. HF(aq) + H2O(l) H3O+(aq) + F- (aq) Hydrofluoric acid

1. HF(aq) + H2O(l) H3O+(aq) + F- (aq) Hydrofluoric acid dissociates in water as represented by the above equation With Ka = 7.2 * 10^-4 A) write the equilibrium- constant expression for the dissociation of HF(aq) in water B) calculate the molar concentration of H3O+ in a 0.4M HF solution HF reacts with NaOHaq according to the reaction represented below HF (aq) + OH-(aq) --> H2O(l) + F-(aq) A volume of 15ml of 0.4 M NaOH is added to 25ml of 0.4M HF aq solution. Assume that the volumes are additive C) calculate the number of moles of HF(aq) remaining in the solution D) calculate the molar concentration of F-(aq) in the solution E) calculate the pH of the solution
