Answer:
Precipitation reactions
Explanation:
Hard water contain high amount of minerals like calcium and magnesium. Water is turned hard, when it passes through limestone or chalk deposits that are majorly composed of bicarbonates of magnesium and calcium.
Precipitation reaction refer to the process that solidifies the insoluble ion particles in water. This solid product can be in the form of crystal or in powder form and it settles at the bottom of the water. The soluble products will still remain in the water.
The precipitation reactions is used to remove Calcium and magnesium ions from hard water. During this process, sodium carbonate or washing soda is added into the hard water which immobilize the Calcium and magnesium ions and results in the precipitation of these ions. This is because sodium chloride is solid, it will be removed and we will get soft water left.
Sodium Carbonate+Calcium Chloride → Sodium Chloride
+Calcium Carbonate
Na2CO3 + CaCl2 → 2NaCl +CaCO3
