Question

At what temperature is more KCl able to dissolve: 40°C or 90°C?

(You don't have to give out a paragraph, but also explain why, so that I may understand)

Answer 1

I believe it would be 90° c, This is because solubility increases with increase in temperature, and therefore more solute would dissolve at a higher temperature. Hence, more KCl will dissolve at a temperature of 90°C as compared to a temperature of 40° C.
