Respuesta :
a. carbonate + water ⇄ hydroxide + carbonic acid
b. c6h5nh2 + water ⇄ hydroxide + c6h5nh3+
c. c2h5nh2 + water ⇄ hydroxide + c2h5nh2+
Bases produce OH- when they react with water.
A weak base is a substance that ionizes only to a small extent in water. A weak base remains largely undissociated in water. Recall that bases produce OH- in solution.
The equation of the reaction by which the following species produce OH- in water are shown below;
CO3^2-(aq) + H2O(l) -------> HCO2^-(aq) + OH^-(aq)
C6H5NH2(aq) + H2O(l) -------> C6H5NH3^+(aq) + OH^-(aq)
C2H5NH2(aq) + H2O(l) -------> C2H5NH3^+(aq) + OH^-(aq)
