| Abstract: | By using EDTA titration of calcium and magnesium,the experiments measured the hardness of water samples in Zhaoqing city and compared it with the provisions of the World Health Organization for water hardness.The data show that the water samples from running water.West River and North Ridge are of medium hardness,the total hardness is between 60~120 mg/L,meeting the health standards for drinking water;water samples from the Star Lake and the direct drinking water are soft water,with total hardness between 0~60 mg/L. |
