it becomes soft
yes
Water is a universal solvent and there are two types of water i.e hard water and soft water. Soft water is the water that easily lather with soap while hard water does not lather with soap and is also of two type i.e temporary and permanent.
Hard water contain calcium bicarbonate, magnesium bicarbonate in temporary hard water and calcium/magnesium sulfate in permanent hard water. Soft water contain doesn't contain these substances or only in very limited concentations.
Hard water contains bicarbonates of calcium and magnesium or sulphates and chlorides od calcium and magnesium . It can be converted to soft water by boiling or by adding calculated quantity of calcium hydroxide .
Boiling can help remove temporary hardness by precipitating the minerals causing it, making the water softer. Passing the boiled water through a filter can further remove any precipitated particles. Adding soap to the now softened water should result in better lathering as the soap can more effectively interact with the water molecules.
Yes
Hard water has more calcium than soft water does
hard water can be converted to soft water by boiling, filteration etc.
it is soft water
Hard water can be converted into soft water through a process called ion exchange. This involves passing the hard water through a water softener that contains resin beads with sodium ions attached to them. As the hard water flows through the resin bed, the calcium and magnesium ions in the water are exchanged for sodium ions, resulting in soft water.
Because hard water is better than soft water for drinking
