Determine if the following salt is neutral, acidic or basic.

Question

If acidic or basic, write the appropriate equilibrium equation for the acid or base that exists when the salt is dissolved in aqueous solution. If neutral, simply write only NR. Be sure to include the proper phases for all species within the reaction. NaCN

Answer 1

If a salt is made from a strong acid and a weak base, the salt will be acidic.

If a salt is made from a strong base and a weak acid, the salt will be basid.

If a salt is made from a strong acid and a strong base, the salt will be neutral.

For NaCN, this salt is made from NaOH (a strong base) and HCN (a weak acid). It will be basic.

The equilibrium equation is: CN^-(aq) + H₂O(l) ==> HCN(aq) + OH^-(aq)
