Clearly indicate if each of the following is True or False: 1.1 Nitrates and phosphates are major contributors to electrical conductivity in water. 1.2 You do need to wash electrode between different sample measurements of pH. 1.3 Measurement of pH using color change method is preferable for more accuracy. 1.4 Volatile suspended solids represent the organic fraction of suspended solids in a sample. 1.5 Fixed solids in a sample are the residue remaining after burning for 30 min at 550°C. 1.6 The pH value of a solution can be negative or less than zero. 1.7 We use turbidemeter to measure the concentration of total suspended solids. 1.8 We do electrical conductivity test to see if we can use water as an electric conductor. 1.9 Turbidity may come from silt, mud, organic and inorganic matters, bacteria, and chemicals. 1.10 PPE stand for personal protection equipment.

1. Calculate a predominance diagram showing the solubility of Ferric hydroxide [Fe(OH)3(s)] as a function of solution pH by plotting the logarithm of the concentration of each iron species against pH assuming the solution is in contact with ferric hydroxide mineral. (10 pts) Before beginning, answer these questions: i) Is this solution open or closed with respect to iron? (2 pts) ii) If open, what is the reservoir for iron? (2 pts) 2. Now plot the same diagram showing the logarithm of iron species concentration as a function of pH for a solution in equilibrium with Ferric hydroxide but that also contains 0.001 moles/kg of dissolved fluoride. Fluoride can form iron complexes via this reaction: FeF+2(aq) + 3 H₂O(1) = Fe(OH)3(s) + 3 H*(aq) + F¯(aq) Include this latter species FeF+2(aq) in the diagram. Ignore all other Fe-F complexes.
