1. What is the conjugate acid of HCN

answer.

H2CN+

to determine the conjugate acid one must take the formula of the base,HCN, and add a proton (H+) to this formula

base formula (HCN) + one proton(H+) = H2CN+

The conjugate acid has one more H+ than its base.

1. What is the conjugate acid of H2O

answer.

H3O+

to determine the conjugate acid one must take the formula of the base,H2O, and add a proton (H+) to this formula

base formula (H2O) + one proton(H+) = H3O+

The conjugate acid has one more H+ than its base.
