What is th pH value of slake lime?

The pH value of slaked lime, also known as calcium hydroxide, is around 12-13. It is considered basic or alkaline due to its ability to release hydroxide ions in water.


Is slaking of lime reversible?

Yes but it is not a single step reversal. You start off with Limestone (CaCO3) you heat this and drive off Carbon dioxide (CO2) making Quicklime (CaO). You then slake the Quicklime by adding water (H2O) to make Slaked Lime (Ca(OH)2). The Slaked lime will slowly turn back into limestone by reacting with the Carbon Dioxide (CO2) in the air - it is Carbonated - to make Limestone (CaCO3).


Where to buy slake lime?

Farm supply stores are probably your best bet. There's a confusing number of similar names for three related compounds: Calcium carbonate, calcium hydroxide, and calcium oxide. "Slaked lime" or "hydrated lime" is calcium hydroxide; this is the one you're asking about. "Lime," "crushed lime," or "agricultural lime" is calcium carbonate. You don't want that one. "Quicklime" or "burnt lime" is calcium oxide. You don't really want that one either, though if that's all you can find it does react with water to form slaked lime.


What is the difference between slaked lime and lime water?

When you slake a lime an leave it for a few months, there will be a layer of water (providing you used a sufficient amount) ontop of the slaked lime putty. this water is limewater and is clear but contains tiny particles in suspension. The putty is what we refer to as slaked lime.


What is the difference between soda lime and lime soda?

Soda lime is a mixture of sodium hydroxide and calcium hydroxide used to absorb carbon dioxide. Lime soda is a solution of lime (calcium hydroxide) and soda (sodium carbonate), often used in water treatment to soften water by precipitating calcium and magnesium ions.
