Chemistry (Solubility)

Question

To what temperature must a mixture of 500g of water at 20°C and

30g of KClO3 be raised in order for the solute to dissolve completely?

Answer 1

According to the solubility chart that I found, KClO₃ is soluble at 20ºC to the extent of approximately 10 g per 100 g of H₂O. So, at 20ºC 500 g of H₂O would be able to "hold" 50 g of KClO₃. That is, you wouldn't have to raise the temperature at all because 30 g KClO₃ would be soluble in 500 g of H₂O at 20ºC
