Question

If 15 g of kclo3 are stirred into 200 g of water at 25 c, how much of the kclo3 will dissolve? is the solution saturated, unsaturated, or supersaturated?

Answer 1

• All 15.0 g of KClO₃ will dissolve completely in water.

• This is unsaturated solution

Step-by-step explanation:

∵ The solubility of KClO₃ in water is 8.15 g / 100.0 g of water at 25°C.

∴ The solubility of KClO₃ in water is 16.3 g / 200.0 g of water.

when 15 g of KClO₃ are stirred into 200 g of water at 25°C: the added amount is less than that is soluble in water, so all 15.0 g of KClO₃ will dissolve completely in water.

And this is unsaturated solution, since the added amount is less than the solubility in water.
