calcium hydroxide 並不是完全soluble於水..但為何lime water 會那麼clear, 而沒有一些未dissolve的calcium hydroxide??

✔ 最佳答案
We can make limewater by adding solid calcium hydroxide(usually in powder form) into distilled water. Then, filter the solution and the limewater is obtained as filtrate, which is a clear, colorless solution. Undissolved calcium hydroxide may also be removed by performing decantation too.
