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
