WebThe ions of calcium and magnesium are responsible for the hardness of water and the formation of scum in hard water. The ions of Sodium (Na) will remain present in the water in the dissolved form. The chemical reaction for the formation of scum will be as below: 2 (C17H35COONa) = (C17H35COO)2Ca + (C17H35COO)2Mg Webmagnesium and calcium ions that are responsible for water hardness. A colour change is observed when EDTA replaces the indicator molecule as the ligand in the divalent ion complex. Solubility products will be used to our advantage when determining the calcium hardness. You are encouraged to bring your own water sample to study. Required Reading

Both calcium hydrogencarbonate and magnesium... WebThe bicarbonates of calcium and magnesium ions cause the temporary hardness of water, which is the difference between temporary and permanent hardness. The sulphates and chlorides of calcium and magnesium cause permanent hardness in the water. Is the hardness of sea water temporary or permanent?
WebThus by passing hard water through a cylinder packed with permutit, all the ions of soluble salts of calcium and magnesium responsible for the hardness of water are retained and replaced by sodium ions. In due course, however, the permutit is exhausted or losses its capacity of reacting with these salts by having given up all its sodium ions. Web29 jun. 2024 · There are two major types of water hardness. The first is temporary hardness, caused by increased magnesium and/or calcium hydrogencarbonate. The other is permanent hardness, brought about by the presence of magnesium and/or calcium sulfate. Temporary hardness is less detrimental because it can be eliminated through …
