About half of the sodium carbonate produced is used in making glass products because it lowers the melting point of the sand, the major component of glass. When sodium carbonate is added to water it hydrolyses according to the following reactions: CO32- (aq) + H2O (l) HCO3- (aq) + OH- (aq), with K1 HCO3- (aq) + H2O (l) H2CO3 (aq) + OH- (aq), with K2 These can be combined to yield: CO32- (aq) + 2 H2O (l) H2CO3 (aq) + 2 OH- (aq), with K3 In terms of K1 and K2, what is the value of K3?
