When KCI dissolved in water When KCI dissolved in water Solution Ans : KCl is an ionic compound. So when it is dissolved in water , it splits into its ions : K + and Cl - . The oxygen of the water molecule being electronegative in nature surround the positive potassium ion and hydrogen surrounds the negative Chlorine ion due to the electrostatic forces formed between the oppositely charged ions. This forms the sphere of hydration around the ions , which prevent them forming an ionic bond in the aqueous solution. The reaction is given as : KCl + H2O = K + + Cl - + H2O .
