Question

Complete this brønsted-lowry reaction placing each product by its appropriate label. hso4- + hcn

Answer 1

Answer : The balanced reaction is, $HSO_4^-+HCN\rightleftharpoons H_2SO_4+CN^-$

Explanation :

According to the Brønsted-lowry concept, a substance is known as acid if it can donate a proton and as a base if it can accept a proton.

The given substance may be a molecule of an ion. The reaction of an acid with the base constitutes the transfer of a proton from acid to the base.

The balanced reaction will be,

$HSO_4^-+HCN\rightleftharpoons H_2SO_4+CN^-$

In this reaction, $HCN$ is an acid and is donating a proton to the base $HSO_4^-$ and both are the reactants. $H_2SO_4$ is the conjugate acid of $HSO_4^-$ and $CN^-$ is the conjugate base of $HCN$ and $H_2SO_4\text{ and }CN^-$ are the products.

Hence, the balanced reaction is, $HSO_4^-+HCN\rightleftharpoons H_2SO_4+CN^-$
