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^-`
