Question

What happens when borax solution is acidified? Write a balanced equations to support your answer.

Answer 1

"When borax solution is acidified the following reaction takes place

${ Na }_{ 2 }{ B }_{ 2 }{ O }_{ 7 }\quad +\quad 2HCl\quad +\quad 5H_{ 2 }O\quad \longrightarrow \quad 2NaCl\quad +\quad 4{ H }_{ 3 }{ BO }_{ 3 }$

Being a weak acid Borax hydrolyzed in solution and is alkaline in nature

${ B }_{ 2 }{ O }_{ 7 }^{ 2- }\quad +\quad 7H_{ 2 }O\quad \longrightarrow \quad 2OH^{ - }\quad +\quad 4{ H }_{ 3 }{ BO }_{ 3 }$ "
