1. For measuring the basicity , calcium stiffness and total hardness, a new successively titrating way is recommended.

2. The volume of silver nitrate titrating solution consumed to measure the chlorides in the test sample is

3. This buffer can be prepared by titrating Acetic acid with a hydroxide or by mixing equal volumes of equimolar Acetic acid and sodium acetate solutions

4. When titrating, how does the pH change as titrant is added? Is change in pH consistent for all Aliquots of added titrant or not? Explain

5. In the first procedure, a total of isothiocyanate and isocyanate is determined by reacting the mixture with excessn-butylamine and back titrating the residual amine acidimetrically.

6. The actual concentration is determined by adding an excess of iodine to an aliquot of the solution and back titrating with standardized sodium thiosulphate solution (see Annex B).

7. We can calculate the amount of Alkalinity in water by titrating the sample water with an acid, using an indicator to determine when the sample water's pH has dropped to a certain level - the endpoint.
