Answer: option (1) the solubility of the solution increases.Rationale:the solubility of The substances in a given solvent is dependent on temperature.The most common behavior of the solubility of the salts in the water is that the solubiilty increases as the temperature increases.To predict with certainty the solubility at different temperatures you need the product constant of solubility (Kps), which is a constant of equlibrium of the dissolution of an ionic compound slightly soluble in water, or a graphic (usually experimental graph) that shows the solubility at different temperatures.KClO₃ is highly soluble in water, so that I don't work with Cap.You need the solubility chart, or just assume that is the normal behavior of the most common of the salts. You may know of the ordinary experience that you can dissolve more sodium chloride (table salt) in the water, when the water is hot. That is the same with KClO₃.The solubility chart KlO₃ is almost a straight line (slightly curved upwards), with a positive slope (rising from left to right) which means that the higher the temperature, the more the amount of salt that can be dissolved.
