Q 3. Pragya tested the solubility of three different substances at different temperatures and collected the data as given below (results are given in the following table, as grams of a substance dissolved in 100 grams of water to form a saturated solution).
(d) What is the effect of change of temperature on the solubility of a salt?
Solubility is directly proportional to the temperature.
Therefore, on increasing temperature, solubility of salt increases.
