The Compounds that may Form During the Reaction are: These appear as a precipitate on the surface of the water, which is scum. It is found that 23 cm 3 of soap solution is needed to form a long-lasting lather. In this way, water becomes free from Ca2+ or Mg2+ ions, and no longer remains hard. This hardness can be removed through a water softener. If rainwater lands in an area with porous rock such as limestone, the water penetrates the ground and as it passes through collects and dissolves particles and minerals such as calcium and magnesium, gaining its hardness. What is the water hardness for my area? This complex anion further releases Na+ ions and captures all the Ca2+ or Mg2+ ions. Hard water is water that contains high amounts of Ca 2+ and/or Mg 2+.Sometimes Mn 2+ and other multivalent cations are included in the measure of hardness. Water is the most important compound that is needed for the survival of life on earth. When we boil the water, the reaction takes place in the following manner: Ca(HCO3)2                     →    CaCO3            +             H2O +     CO2, Calcium Bicarbonate  Calcium Carbonate   Water    Carbon Dioxide, Mg(HCO3)2                         →     Mg(OH)2                      +                 CO2, Calcium Bicarbonate  →   Magnesium Hydroxide      Carbon Dioxide. Water hardness is commonly measured in milligrams per liter (mg/L) or grains of mineral per gallon (GPG). For example, water from an underground aquifer will be harder than water from a river or lake. So, what makes the water hard? As the mineral content in the water increases, the water is considered “harder”. The hardness of finished water at the Henrico County Water Treatment Plant averages 64 milligrams per liter, or about 4 grains per gallon. Contingent upon where a water test is performed this data will be accounted for in mg/L (milligrams per Liter) or GPG (grains per gallon). This type of hard water may be softened by using an ion exchange column or water softener. Find out what 'hard' water means and how it affects water quality.
