Calcium hydroxide is not very soluble in water at room temperature (less than 0.2 grams/100 mL).
When mixed with water and filtered, much of the Calcium hydroxide will be held in the filter paper.
The filtrate is called lime water and it is used to test for the presence of Carbon dioxide. It will react with CO2 to form Calcium Carbonate (CaCO3) which is a white

Ca + 2H2O -> Ca(OH)2 + H2: exothermic
The soubility of Ca(OH)2 in water is very low, so you will get a white suspension
