Answer:

NaNO₃.

Step-by-step explanation:

  • From the attached figure, the solubility of the different salts is:
  • KNO₃:

It is 90 g per 100 g water.

  • NaNO₃:

It is 110 g per 100 g water.

  • KClO₃:

It is about 20 g per 100 g water.

  • NaCl:

It is about 40 g per 100 g water.

So, the most soluble salt at 50°C is NaNO₃.
