What would you observe in a solution of 30 g of kc1o3 in 100 g of water at 10 c?
a. about 5 g of the kc1o3 is dissolved
b. about 20 g of the kc1o3 is dissolved
c. all of the kc1o3 is dissolved
d. none of the kc1o3 is dissolved

Option A is correct. About 5 g of the KClO3 is dissolved

Explanation:

KClO3 is not very good soluble in water.

So, Option C is impossible, because KClO3 is poorly soluble in water.

The low solubility of KClO3 in water causes KClO3 to isolate itself from the reaction mixture by precipitating out of solution.

So, option D will either happen.There will be a part of KClO3 dissolve.

At 10 °C, KClO3 has a solubility of 4.46 g/100 gram (10 °C).

Option A is correct. About 5 g of the KClO3 is dissolved
