Question

What is the minimum temperature
needed to dissolve 35 grams of KCl in 100 grams of water?

Answer 1

`30^(\circ)\text{C}`

Step-by-step explanation:

To know the temperature at which KCl dissolves in water we need to refer to the general solubility curves.

In the case of
`KCl`,
`35\ \text{g}` of it will dissolve in
`100\ \text{g}` of water at a minimum temperature of
`30^(\circ)\text{C}`.

So, the the minimum temperature needed to dissolve 35 grams of KCl in 100 grams of water is
`30^(\circ)\text{C}`.
