Which will not be hydrolysed?

• A. Potassium Nitrate
• B. Potassium Cyanide
• C. Potassium Succinate
• D. Potassium Carbonate

To determine which compound will not undergo hydrolysis, we need to consider the nature of each substance. Hydrolysis typically occurs with salts that contain anions from weak acids or cations from weak bases.

Analysis of Each Option

• Potassium Nitrate (A): This salt is formed from a strong acid (nitric acid) and a strong base (potassium hydroxide). It does not hydrolyze.
• Potassium Cyanide (B): This salt comes from a weak acid (hydrocyanic acid) and a strong base. It will hydrolyze, producing hydroxide ions.
• Potassium Succinate (C): This salt is derived from a weak acid (succinic acid) and a strong base. It will also undergo hydrolysis.
• Potassium Carbonate (D): This salt is formed from a strong base (potassium hydroxide) and a weak acid (carbonic acid). It will hydrolyze, leading to the formation of hydroxide ions.

Final Answer

The compound that will not be hydrolyzed is Potassium Nitrate (A).
