Lime water, what is it?

You can easily guess, lime water is nothing but a solution of water and lime. So far we're not teaching you anything! But do you know exactly what lime is?

Lime comes from a sedimentary rock found in large quantities on Earth, limestone (CaCO3). To obtain it, it is sufficient to bring blocks of limestone to a very high temperature, around 900°C. This produces a white powder called quicklime, also known as calcium oxide (CaO). There are several kinds of lime. The high quicklime is the powder obtained directly after calcination. If hydrated, quicklime turns into slaked lime also called air lime and known as calcium hydroxide (Ca(OH)2). This transformation is also accompanied by a strong release of heat. And the last lime you are likely to know is hydraulic lime. In this case, the limestone used is quite often impure and composed of other rocks such as clays. Hydraulic lime is, like air lime, obtained after hydration.

To obtain limewater, air lime is used. In the form of a fine white powder, air lime dissolves in water. Once the lime is completely dissolved, the mixture is filtered. The resulting solution is a saturated solution of calcium hydroxide also called lime water! Tadam!
