Web2. Predict whether the following errors would raise, lower or not affect the calculated value for water hardness. Explain. a. The molarity of the EDTA was incorrectly reported as a value that was larger than the true molarity of the EDTA.(Refer to equations 5-7 in your answer.) (3 pts.)By making EDTA's molarity greater, this would affect the result of equation # 5, since … Webfollowing formula: Degree of Hardness = The weight of hardness causing salts × 100 (Molecular weight of CaCO 3) Molecular weight of hardness causing salts Units of Hardness: 1. Parts per Million (ppm): The number of parts of calcium carbonate equivalent hardness presents in 106 parts of water. 1ppm = 1 6 part of CaCO 3
