Actually most of the salts are insoluble in water. Not all the salts include chloride!!! And of those witch contain chloride, silver, led and mercury salts are insoluble!!! chemically speaking, not all salts are soluble in a particular solvent under normal conditions..
All Alkali cations like Na, K NH4 are soluble in water. All anions like Bicarbonates, halides, sulphates, Nitrates are soluble. So for a salt to be soluble in water, it should have at least either one radicle from the above cation or anion. In case of KCl, both of the radicles belong to the soluble category.
