Lime Stone and The Lime Cycle

Lime stone is Calcuim carbonate and the chemical symbol for this is CaCO3.

The Lime Cycle:

1) Calcium carbonategoes through THERMAL DECOMPOSITION and a by product of this is CARBON DIOXIDE this then producesCALCIUM OXIDE (CaO)

2) Then you add A FEW DROPS OF WATERto the CALCIUM OXIDE to produce CALCIUM HYDROXIDE Ca(OH)2

3) ADD MORE WATER TO THE CALCUIM HYDROXIDE AND THEN FILTER! This produces CALCUIM HYDROXIDE SOLUTION

4) ADD CARBON DIOXIDE to the CALCUIM HYDROXIDE SOLUTION. This should then take you back to CALCUIM CARBONATE. However a by product of this is WATER (H2O)
