Answer 1

Answer #1

a) HCl_(aq) + H2O_(l) -------------> H3O⁺_(aq) + Cl^-_(aq) HCl is strong acid so dissociates completely

b) H2SO3_(aq) + H2O_(l) <-----------> HSO3^-_(aq) + H3O⁺_(aq) H2SO3 is weak acid so dissociates partialy

for weak acids

Ka = [H3O⁺][HSO3^-]/[H2SO3]

c) HNO3_(aq) + H2O_(l) ------------> H3O⁺_(aq) + NO3^-_(aq) HNO3 is strong acid so dissociates completely.

d) HCN_(aq) + H2O_(l)<--------------> CN^-_(aq) + H3O⁺_(aq) HCN is weak acid so dissociates partially

Ka = [H3O⁺][CN^-] / [HCN]
