tough water in Chemistry - Assignment ExampleC02 and water reacts with each other carbonic acid. carboniferous acid usually exists as a bicarbonate ion at a normal environmental pH. (figure 1) . huge limestone deposits have been built up over the years by microorganism by taking up of this carbonic acid. Groundwater acquires calcium and bicarbonate ions and hence becomes hard. If the bicarbonate ions are a lot therefore they may form a precipitate like that in pipes. (Figure 2)Temporary hardnessTemporary hardness is referred to such water that fuck lose its hardness by simply boiling it. Boiling water gives rise to the following reaction2 HCO3 CO32+ CO2CO32reacts with atomic number 20or Magnesiumions. This leads to the formation of a precipitate. This precipitate is actually calcium and magnesium carbonates which are insoluble in nature.Water that doesnt lose it hardness by boiling is known to be permanently hard. This is generally due to the presence of chloride or sulphate, that is, it contains anions. Traditional water softening is usually carried out through a process that is known as ion exchange. Ion exchange refers to the process in which chloride and sodium ions exchange places. These ions are fixed comparatively loosely to something called a zeolite. Zeolite may be understood referring to figure 3 in the appendix,Although they is sort of some proof that electromagnetic devices may be useful in preventing the formation of scale.
