Kalk Stirrers, Deltec

Kalk Stirrers

Kalkwasser - Translates from the German for limewater and is a solution made by dissolving Calcium Hydroxide in water. The resultant solution is alkaline with a pH of 12.4 and contains a ready supply of both Calcium ions and Carbonate ions.

The solution reacts readily with CO2 in the atmosphere to form calcium carbonate and so it must be made in a relatively air tight environment which is where the Deltec kalkwasser stirrer comes in to play.
