The correct order of increasing pH values of the aqueous solutions of

1.	The correct order of increasing pH values of the aqueous solutions of baking soda, rock salt, washing soda and slaked lime is1. Baking Soda < Rock Salt < Washing Soda < Slaked lime2. Rock Salt < Baking Soda < Washing Soda <Slaked lime3. Slaked lime < Washing Soda < Rock Salt < Baking Soda4. Washing Soda < Baking Soda < Rock Salt < Slaked lime
Answer» Correct option: 2. Rock Salt < Baking Soda < Washing Soda <Slaked lime Explanation: Rock salts (NaCl) - Neutral salt Baking soda (NaHCO₃) - Basic salt Washing soda (Na₂CO₃. 10H₂O) - basic salt Slaked lime (Ca(OH)2) - Base Increasing order of pH : Acid < Salt < Base ∴ correct order of increasing pH values of aqueous solution of : Rock Salt < Baking soda < Washing soda < Slaked lime

Answer»

Correct option: 2. Rock Salt < Baking Soda < Washing Soda <Slaked lime

Explanation:

Rock salts (NaCl) - Neutral salt

Baking soda (NaHCO₃) - Basic salt

Washing soda (Na₂CO₃. 10H₂O) - basic salt

Slaked lime (Ca(OH)2) - Base

Increasing order of pH : Acid < Salt < Base

∴ correct order of increasing pH values of aqueous solution of :

Rock Salt < Baking soda < Washing soda < Slaked lime
