TOTAL HARDNESS 1. Rinse test tube with the water to be analysed. 2. Fill test tube with the water to be analysed up to the 5 ml mark. 3. Add Titrant drop by drop mixing after each addition. Count the drops to the colour change from red to green. According to the Titrant used, in a 5 ml sample each drop corresponds to half the value indicated on the bottle, in a 10 ml sample each drop corresponds te half the value indicated on the bottle.

TOTAL HARDNESS Direction for use 1. Rinse the measuring vessel with the water to be tested and fill up the 5ml. mark. 2. Add 1-2 drops of indicator and swirl. In presence of hardness higher than 3 ppm CaCO3 a wine red colour will appear (A blue color indicates absence of hardness. With hardness lower than 3 ppm the colour of the sample shifts from violet. to grey to pink). 3.Add titrant drop by drop, mixing after each addition. Count the drops until the colour changes from red to blue. Each drop corresp
