The notion of the solubility product constant, {eq}K_{sp} {/eq} provides a quantitative understanding of how much a salt (even a supposedly insoluble one) actually dissolves in water. By writing out the dissolution equation and applying the stoichiometric relations between...
Potassium chlorate is an ionic compound having the chemical formula KClO3. This compound appears as a white crystalline substance when it is in pure form. In industrial applications, this is the second most common chlorate compound, according to its importance, aftersodium chlorate. Potassium chlorate...
