Aq. solution of sodium cyanide is — Ionic Equilibrium Chemistry Question

💡 Solution & Explanation

I need to see the options to provide a complete solution. However, based on chemistry principles, here's the reasoning for aqueous sodium cyanide ($NaCN$): **Step 1: Identify the salt type** $NaCN$ is a salt of a strong base ($NaOH$) and a weak acid ($HCN$). **Step 2: Determine hydrolysis** The cyanide ion ($CN^-$) undergoes hydrolysis: $$CN^- + H_2O \rightleftharpoons HCN + OH^-$$ **Step 3: Assess pH character** Since $CN^-$ produces $OH^-$ ions, the solution is **basic** (alkaline). **Step 4: Conductivity consideration** The solution conducts electricity due to $Na^+$ and $CN^-$ ions, plus ions from hydrolysis ($OH^-$ and $HCN$). --- **Most likely correct answer C would be:** "Basic" or "Alkaline in nature" If the options include other characteristics (like "acidic," "neutral," "conducts electricity," etc.), the basic nature due to hydrolysis of the weak acid's conjugate base is the defining property. *Could you provide the options so I can confirm which specific statement (C) is correct?*
