Question

(A) The reaction of borax $(Na_2B_4O_7)$ with $HCl$ and water is given by:$Na_2B_4O_7 + 2HCl + 5H_2O 	o 2NaCl + 4H_3BO_3$Thus,$A = Na_2B_4O_7$ and $X

Vedclass · Accepted Answer

$A = Na_2B_4O_7, X = H_3BO_3, Z = B_2O_3$

(A) The reaction of borax $(Na_2B_4O_7)$ with $HCl$ and water is given by:$Na_2B_4O_7 + 2HCl + 5H_2O 	o 2NaCl + 4H_3BO_3$Thus,$A = Na_2B_4O_7$ and $X = H_3BO_3$.On heating orthoboric acid $(H_3BO_3)$ at $370 \ K$,it forms metaboric acid $(HBO_2)$:$H_3BO_3 \xrightarrow[370 \ K]{\Delta} HBO_2 + H_2O$On further heating above $370 \ K$,metaboric acid $(HBO_2)$ dehydrates to form boron trioxide $(B_2O_3)$:$2HBO_2 \xrightarrow[> 370 \ K]{\Delta} B_2O_3 + H_2O$Therefore,$Z = B_2O_3$.

Identify the compounds $A$,$X$ and $Z$ in the following reactions :
$A + 2HCl + 5H_2O \to 2NaCl + X$
$X$ $\xrightarrow[370 \ K]{\Delta} HBO_2$ $\xrightarrow[> 370 \ K]{\Delta} Z$
