Answer

Answer:

Na₂HAsO₄ and NaCl

Explanation:

Step1: Locate 40°C on x - axis

Find the 40°C mark on the temperature axis.

Step2: Check solubilities of salts

Read the solubility values of each salt at 40°C from the graph. For Na₂HAsO₄ and NaCl, their solubility values are close to each other at 40°C compared to other pairs.
