Question

Write a reaction equation showing how a buffer solution made from combining aqueous solutions of HCN and NaCN will neutralize an added base.

Accepted Answer

HCN(aq) + $$OH^{–}(aq$$) → $$CN^{–}(aq$$) + $$H_{2}O(l)$$

Answer

HCN(aq) + $$H_{2}O(aq$$) → $$CN^{–}(aq$$) + $$OH^{–}(aq)$$

Answer

$$CN^{–}(aq$$) + $$OH^{–}(aq$$) → $$CN^{–}(aq$$) + $$H_{2}O(l)$$

Answer

$$CN^{–}(aq$$) + $$H_{2}O(aq$$) → HCN(aq) + $$H_{3}$O^{+}(aq)$$
