water test kit hardness

sensitivity : 1 drop=1 Fr hardness , 1 drop=1 Hardness Hd

general information : water hardness dissolved calcium or magnesium salts of the soap and the water from precipitation come forward in a major capacity. Soap, especially by calcium and magnesium ions in water is always cokeltili. But at the same time that this precipitation of Fe, Al, MN and Zn and precious metals such as may be caused by hydrogen ions. Hardness, calcium and magnesium ions are expressed as total concentrations in terms of calcium carbonate. However, the transmitter can include other amounts of hardness ions that can be displayed. Total hardness test kit determines quantitatively the presence of all ions of water hardness.

application method : Titrimetric
1) in a test tube, rinsed several times with water to be tested.
2) 5 ml of the test tube. to be tested is filled with water to the marked line.
3) Apply two drops of the indicator MB. Close the lid and shake vigorously.
4) If color is blue, the water hardness in the ion transmitter. (water is soft)
5) if Color Is Pink, add total hardness titration solution and the drops of the purple color first, then gently shake the container until he turns blue, and the amount of drop is counted. 6) each DRIP titration solution =1 Fr0 (1 French is equal to the hardness).
Information: 1 Fr0 = 10 ppm CaCO3 = 0,2 epm = 0,2 mval/l 1 epm = 50 ppm CaCO3 = 1 mval/l
