Chemistry - Difference between quick lime, slaked lime, lime water and soda lime

Solution 1:

Quick lime is calcium oxide, $\ce{CaO}$, in the solid state.

Slaked lime is calcium hydroxide, $\ce{Ca(OH)2}$, in the solid state.

Lime water is a dilute solution of calcium hydroxide, $\ce{Ca(OH)2}$, in water.

Soda lime is a mixture of sodium hydroxide, $\ce{NaOH}$, (also known as caustic soda) and calcium oxide, $\ce{CaO}$, (also known as quicklime).

Solution 2:

To add to the family of materials in the 'lime' category: The sedimentary rock limestone is composed of calcium carbonate, $\ce{CaCO3}$.

Solution 3:

According to Wikipedia:

Quick lime is $\ce{CaO}$ (calcium oxide)
Slaked lime is $\ce{Ca(OH)2}$ (calcium hydroxide)
Lime water is just a dilute solution of calcium hydroxide.
Soda lime is a mixture of about 75% calcium hydroxide, a few percent each of sodium hydroxide and potassium hydroxide, and about 20% water. It is commonly used to adsorb $\ce{CO2}$ from the air.
