Procedure For Test
Measure a clear 50-ml sample of water in the graduated cylinder and transfer to the casserole. Add 4 drops of methyl orange indicator. Titrate from the buret with standard 0.02N sodium carbonate until, the color changes from pink to yellow. Record the volume (ml) of sodium carbonate required. Calculation of Results
FORMULA : ppm FMA CaCO3 = Ml 0.02N sodium carbonate x 1000 / ml sample
Using a 50 ml sample, the free mineral acidity in ppm CaCO3 is equal to ml of 0.02N sodium carbonate multiplied by 20.
FMA : Free mineral acidity
Limitations of Test
Colored or turbid samples may obscure color change at the end point. A pH meter may be used as an indicator in these situations with titration to pH 4.3. The pH meter should be calibrated prior to use by an appropriate standard buffer. Free available chlorine in the sample may bleach the indicator. This source of interference may be eliminated by treating the sample with one drop of 0.1N sodium thiosulfate.
