Abstract

DC60 (24/01/54) This invention water hardness test kit consists of an amber indicator bottle with a stopper with a dropper, and an amber EDTA solution with a stopper with a dropper. 3 bottles of different concentrations: 1 drop of aqueous etha solution, the sample gave the difference or the concentration of calcium carbonate equal to 10 ppm (parts per million), 20 ppm (in Million) and 50 ppm (parts per million) respectively. Catur tea contains 0.15 g grade eryochrombacteria reagent, 15 ml triethanolamine and 15 ml ethanol solution, 1 drop bottle of brown Edta solution "= 50 ppm ( The buffer solution contains 5.5 ml of concentrated hydrochloric acid mixed with 40 ml of distilled water, diluted with 100 ml of distilled water. 30 ml of nolamine, 2 g of EDTA magnesium salt is dissolved in 100 ml of distilled water and 1 drop of an ethanol solution flask "= 10 ppm (parts per million). ) "And a bottle of brown EDTA solution" 1 drop = 20 ppm (parts per million) "contains one drop of EDTA solution = 50 ppm (parts per million)" Diluted 5 times and 2.5 times respectively. This invention water hardness test kit consists of a colored indicator bottle with a stopper with a dropper, and an amber EDTA solution with a stopper with a stopper. There were 3 different concentrations: 1 drop of aqueous etha solution. The sample gave the difference or the calcium carbonate concentration equal to A. There are 10 ppm (parts per million), 20 ppm (parts per million) and 50 ppm (parts per million) respectively. The amorphous caters contain 0.15 g of grade erythroid bacteria, 15 ml of triethanolamine, and 15 ml of ethanol solution. PPM (parts per million) ”contains 3.7225 g of EDTA mixed with 50 ml of buffer and dissolved with 100 ml of distilled water. The buffer solution used contains 5.5 ml of concentrated hydrochloric acid mixed with distilled water. 40 ml, 30 ml ethanolamine, 2 g EDTA magnesium salt, dissolved with 100 ml of distilled water, and 1 drop of an amulet of ethanol amine solution = 10 ppm. 1 drop of EDTA solution "1 drop = 20 ppm (ppm)" contains EDTA solution "1 drop = 50 ppm. M (parts per million) "diluted 5 times and 2.5 times, respectively.
