A solution of sodium borate has a pH of approximately:

Question

A solution of sodium borate has a pH of approximately: (A) < 7 (B) > 7 (C) 7 (D) between 4 and 5

Tardigrade Admin · Accepted Answer

Sodium borate in solution undergoes hydrolysis and gives a strong base (sodium hydroxide) and a weak acid (H3BO3). Hence, its solution will be basic and consequently the pH will be > 7. Na3BO3+3H2O xrightarrow undersetweak mathopH3BO3 + undersetstrong mathop3NaOH
