Calculate `[OH^(-)]` in a 1M solution of NaOCN . `K_a(HOCN) = 3.3 xx 10^(-4) `.

Explanation

To calculate the concentration of \([OH^-]\) in a 1M solution of NaOCN, we can follow these steps:

### Step 1: Understand the Dissociation of NaOCN
When NaOCN is dissolved in water, it dissociates completely into its ions:
\[ \text{NaOCN} \rightarrow \text{Na}^+ + \text{OCN}^- \]
Since NaOCN is a salt of a strong base (NaOH) and a weak acid (HOCN), the \(\text{OCN}^-\) ion will undergo hydrolysis.
