Question

A mass of 80 g of KNO3 is dissolved in 100 g of water at 50 ºC. The solution is heated to 70ºC. How many more grams of potassium nitrate must be added to make the solution saturated? Explain your reasoning

Answer 1

Hi um i think its At 30 ° C your welcome

Answer 2

50 g more potassium nitrate must be added to make the solution saturated at 70 °C.

Solubility:

It is the degree of dissolved substance at room temperature or 25 °C per  $\bold {g/100\ cm^3}$.

Saturation:

If no more solute or solid substance is dissolved in the solution, then the solution is called saturated.

Saturation increase with the increase in temperature because the kinetic energy of the particles is increased.

Therefore, 50 g more potassium nitrate must be added to make the solution saturated at 70 °C.
