This SOP describes the procedure for measuring hardness by titration with standard EDTA solution to endpoint indicated by a color change. This method is based on Method 2340 C of .Estimation of Hardness of Water by EDTA Method 3 In the pH range 8-10, the blue form of the indicator HD2– gives a wine red complex with Mg2+: Mg+2 + HD 2– MgD– + H+ (Blue) (Wine red) Now if EDTA (H2Y 2–) is added to such a solution Mg2+ preferentially complexes with EDTA (since the metal EDTA complex is more stable than the metal-indicator complex) and liberates .

A DIY water hardness test works by changing color to indicate the minerals present in the water. You can compare the color of the strip to the color chart, which will help you to determine your water hardness. . Add the EDTA drops one by one to the water, waiting between each drop. Continue until your water turns blue. This may take a few .Hardness, Total (mg/L as CaCO 3 ) (Colorimetric, Automated EDTA) ANALYTE: Hardness Total (mg/L as CaCO 3 ) INSTRUMENTATION: Spectrophotometer STORET No.: 00900 1.0 Scope and Application 1.1 This automated method is applicable to drinking, surface, and saline waters.

Test preparation Before starting As an alternative to the ManVer 2 Hardness Indicator Powder Pillow, use 4 drops of Hardness 2 Indicator Solution or a 0.1-gHardness, Calcium & Total: Drop test: EDTA titration (includes inhibitors to prevent metal interference) 1 drop = 10 ppm calcium or total hardness as CaCO₃ .EDTA forms a more stable complex with calcium (log K f = 10.65) than with magnesium (log K f = 8.79). Thus, in solutions (such as natural water samples) that contain both metals, EDTA reacts first with Ca2+, and, when all the Ca2+ ions have been complexed, with Mg2+. When all the free Mg2+ has been complexed by EDTA, the remaining free

water hardness titration calculation

Hardness Calculation: Total Hardness as CaCO3 (ppm) = (TV X Normality of EDTA X 1000 X 50)/ Sample volume. Note: If heavy metals like Iron are high, add 1 ml of inhibitor solution in hardness test. If alkalinity is more than 300ppm, take 50 ml water sample add 2ml HCl and boil for half an hour and proceed for hardness analysis.

2340 A. Introduction 1. Terminology Originally, water hardness was understood to be a measure of the capacity of water to precipitate soap. Soap is precipitated chiefly by the calcium and magnesium ions present. Other polyvalent cations also may precipitate soap, but they often are in complex forms, frequently with organic constituents, and their role in water hardness may be .

The traditional test for hardness involves pH adjustment to 10.1 with an ammonium buffer, addition of Eriochrome Black T indicator [1-(1-hydroxy-2-naphthylazo)-6-nitro-2-naphthol-4-sulfonic acid] and then titration with Na 2EDTA (ethylenediaminetetraacetic acid, disodium salt) solution. Some other indicators are more stable, giving a faster .

1. n. [Drilling Fluids] A chemical analysis to measure the hardness ions in water-mud filtrates or in make-up water.Hardness is quantitatively determined by titration using standardized EDTA reagent and ammonium hydroxide (weak) buffer, typically according to procedures of API.Results are reported as calcium ion in mg/L.

The ammonia buffer which is used in the test aids in preventing precipitation of metal ions. Hardness caused by Ca² is higher than hardness of Mg². As EDTA is added to solution it combines with Ca² first and then with Mg² .Test Parameter Description; Metal ions may cause interference; to prevent, add titrant containing EDTA to sample before buffer and indicator, then test as normal making sure to count drops of titrant added initially in total required to reach endpoint.EDTA/Water Hardness.
