Volume: 16 x 10 mL Ampules.


Description

Description

The use of standard solutions can provide control of the laboratory process, increase confidence, and help provide a clear demonstration of performance to various inspectors, regulatory agencies and clients. One-parameter analysis can be performed on different analyzed samples and concentrations to confirm accuracy.

Calcium Hardness Standard Solution (218710) from Hach. Concentration 10000 mg/L CaCO3 (NIST).

Platform: Solution.

Summary of method: Potassium hydroxide is added to the sample to adjust the pH to 12 to 13, which causes a magnesium hydroxide precipitate to form. CalVer 2 Calcium Indicator is then added, which reacts with calcium to give a red color. The EDTA titrant is added, which reacts with all the free calcium. After the EDTA has reacted with all of the free calcium ions, the EDTA removes the calcium from the indicator. The indicator color then changes from red to blue.
