Question

Hydrolysis of borax by diagrams
 


Solution

Borax is a colorless, crystalline solid sparingly soluble in cold water but dissolves readily in hot water. It forms two important hydrates: octahedral borax Na2B4O7.5H2O and monoclinic borax Na2B4O7.10H2O.
 

Borax is slightly hydrolyzed in solution. As boric acid is a weak acid, the solution is alkaline in nature.

basic nature of borax a buffer is a mixture of weak acid and its conjugate base
for example CH3COOH + CH3COONa is a buffer in which Ch3COOH is a weak acid and CH3COONa is a conjugate base(formed by the action of weakacidCH3COOH +strong base naOH)

same way B2O7^2- is the ion from the  base  Na2B4O7 accepts H+(proton) from H2O to form weak  acid H3BO3(Boric acid)

a weak acid  is produced by a strong base. 
thus a mixture of B2O7^2- and H3BO3  acts as a buffer by thepresenceof a weak acid H3BO3 and its  base B2O7^2-
