When borax is dissolved in water, it gives an alkaline solution. The alkaline solution consists the following products

Step-by-step solution

When borax is dissolved in water it gives an alkaline solution. The alkaline solution consist OH - ions. When borax is dissolved in aqueous solution the formation of sodium borate and boric acid takes place which forms a strong base hence it is alkaline in nature. Borax has a tendency to dissociate to form B 4 O 7 2 - , so from this we know that after dissociation B 4 O 7 2 -   →   2 OH -   +   4 H 3 BO 3 So from above theory we conclude that NaOH   &   H 3 BO 3 are formed.
