Calcium hydroxide is slightly soluble in water (0.18 g/100mL). It dissolves to give a saturated solution called "lime water".

Calcium hydroxide solution "should" be strongly alkaline, but the low solubility of calcium hydroxide stops the solution having a very high pH. Warning, there is possible confusion over the use of word "strong" in this situation. Hydroxide ion is a strong Brønsted base, but as the calcium salt it can only form a low concentration.
