Answer 1

Explanation:

BF3 + 9H2O= H3BO3 + HBF4 + HF

Answer 2

Answer:

The reaction of BF₃ and H₂O gives H₃BO₃ (orthoboric acid)and [BF₄]⁻ (fluoroborates) .

Explanation:

The complete and balanced equation is:

           4BF₃  +   12H₂O     →    4H₃BO₃ + 12HF

         12HF   +   3H₃BO₃   →    3H⁺ +  3[BF₄]⁻ + 9H₂O

  -----------------------------------------------------------------------------

          4BF₃  +    3H₂O      →   H₃BO₃  +  3H⁺ + 3[BF₄]⁻  

  ------------------------------------------------------------------------------

   HF formed in the reaction, further reacts with H₃BO₃. It leads to the formation of fluoroborates [BF₄]⁻  .
