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 substance dissolved in 100 grams of water to form a saturated solution).

Find the solubility of each salt at 293 K. Which salt has the highest solubility at this temperature?

Explanation

The maximum amount of the salt which is dissolved in 100 g of water to form a saturated solution at the given temperature, is known as solubility.
Solubility of potassium nitrate at 293 K =`(32 )/(100 )`
Solubility of sodium chloride at 293 K =`(36)/(100)`
Solubility of potassium chloride at 293 K =`(35 )/(100)`
Solubility of ammonium chloride at 293 K =`(35)/(100)` From the above data, it is clear that ammonium chloride has the highest solubility at 293 K.
