The concentration ratio of hydrocyanic acid to cyanide ion, [ HCN ] / [ CN − ] , that will produce a buffer solution with a pH of 9.71 is to be calculated. Concept introduction: The acids that do not undergo complete dissociation when dissolved in water are known as weak acids. The equilibrium constant in the case of dissociation of a weak acid is known as the acid constant and is denoted by K a . A solution that resists any change in the value of pH when a very small amount of base or an acid is added to it is known as a buffer solution.
