Question

Two beakers labelled as A and B each containing 50ml of distilled water were taken a pinch of NaCl and pallets of NaOH were added to beakers A & B respectively. What will be your observation? *​

Answer 1

Our observation will be:

(C) In beaker A Endothermic and in B Exothermic process occurs.

- The dissolution of Sodium Chloride (NaCl) in distilled water is an endothermic reaction.

- Hence, the reaction taking place in beaker A is an endothermic reaction.

- The dissolution of Sodium Hydroxide (NaOH) in distilled water is an exothermic reaction.

- Hence, the reaction taking place in beaker B is an exothermic reaction.
