Web24 May 2024 · Temporary hardness is characterized by dissolved bicarbonate minerals (calcium bicarbonate and magnesium bicarbonate) that yield calcium and magnesium cations (Ca 2+, Mg 2+) and carbonate and bicarbonate anions (CO 32−, HCO 3− ). This type of water hardness may be reduced by adding calcium hydroxide to the water or by boiling it. WebExperiments based on hard and soft water There are two types of hardness i.e. temporary hardness and Permanent hardness. Temporary hardness is due to calcium and magnesium bicarbonates. It can be removed by boiling followed by filtration. Permanent hardness is due to the presence of chlorides and sulfates of calcium and magnesium.
WebTemporary water hardness is caused by the presence of bicarbonate minerals (calcium bicarbonate and magnesium bicarbonate). Boiling causes the formation of carbonate from the bicarbonate and precipitates it out, leaving soft water upon cooling. Permanent water hardness is usually caused by chlorides or calcium and magnesium sulfates. WebHard water: Water that contain high amout of dissolved minerls or ions such as calcium, magnesium etc. Soft water: Soft water is surface water that contains very low concentration of ions or minerals, e.g., Rainwater and distilled water. definition Methods of removing temporary hardness
