Dissolved magnesium and calcium ions in water cause permanent hardness of water.
It can be removed by adding SODIUM CARBONATE DECA HYDRATE which is nothing but WASHING SODA with chemical formula Na2CO3.10H2O.
Hope it helps......
Any doubts, comment down or message me.
Mark my answer as brainliest if it helped.
