The solubility of kclo3(s) in water increases as the (1) temperature of the solution increases (2) temperature of the solution decreases (3) pressure on the solution increases (4) pressure on the solution decreases


the solubility of option (1) increases the solution.


The solubility of substances in a particular solvent depends on temperature.

The most common behavior of salt solubility in water is that the solubility increases as the temperature increases.

To definitely predict the solubility at different temperatures you need the product solubility constant (Kps), which is the equlibrium constant of a slightly soluble ionic compound solution, or a chart (usually an experimental chart) showing the solubility at different temperatures.

KClO₃ is highly soluble in water, so you do not work with Kps.

You need the solubility chart or just assume it has the normal behavior of the most common salts. You may know from ordinary experience that you can dissolve more sodium chloride (table salt) in water when the water is hot. This is the same as KClO₃.

The solubility chart of KlO₃ is almost like a straight line (slightly curved upwards), with a positive slope (going up from left to right) which means that the higher the temperature the greater the amount of salt that can dissolve.
