INTRODUCTION
As a general rule, hydroxides and all the salts of the alkali metals are soluble in water, and many of the hydroxides and salts of the alkaline earth metals have very small solubilities. Weak electrolytes are salts with relatively low solubility in water.
When we use the solubility rules to predict whether or not a precipitate will form when two solutions are mixed it is more accurate to say that the precipitate may form rather than the precipitate will form because if the solutions were very dilute, a precipitate might not form. …
