The total hardness of water, expressed as CaCO3 content of water is determined by complexometric titration of calcium and magnesium at pH 10 using EDTA. The color change of the Erio T indicator (violet to blue) at the equivalence point is sensed by a photometric sensor DP5 Phototrode™. ...
total heat- (thermodynamics) a thermodynamic quantity equal to the internal energy of a system plus the product of its volume and pressure; "enthalpy is the amount of energy in a system capable of doing mechanical work" enthalpy,heat content,H ...
The proposed method overcame the deficiencies of the standard method. By measuring the total hardness in surface water, groundwater and standard samples using the standard method and the improved method, the results had no significant differences. Key words: EDTA titration total hardness water buffer...
aIn order to make hard water with a total hardness equivalent to 1000 ppm, 0.01 M CaCl2 and 0.02 M NaHCO3 were mixed and dissolved in tap water. 为了做硬水以总坚硬相当于1000 ppm, 0.01 M氯化钙和0.02 M NaHCO3是混杂和溶化在自来水。 [translate] ...
