If a 25.00 ml aliquot of a solution containing sulfide ions was added to 25.00 ml of 0.0108 M Cu2+ solution. The CuS precipitate was washed and collected. The pH of the combined filtrate and washings was then adjusted by the addition of ammonia and the solution was titrated with 0.01453 M EDTA, using a suitable indicator. The endpoint volume was found to be 12.12ml. Find the molarity of the sulfide in the sample solution.
A 10.0 g sample of KC3H504 (A)(MW = 204.23 g A) was titrated with 50.00 mL of KOH (B) to endpoint. What is the molarity of the KOH solution? Use A and B to show compounds in the working.

One published value for Keq for FeSCN2+ formation is approximately 113 at 20oC. Based on this value, does equilibrium favor the formation of FeSCN2+, or does it favor the reverse reaction? Briefly justify your answer.
A 20 mL volume of 0.015 M KIO3 containing an excess of KI, is added to a 0.312 g sample of a Real Lemon solution containing vitamin C. The Yellow-brown solution, caused by excess I2 is titrated to a colorless starch endpoint with 11.3 mL pf 0.106M Na2S2O3. Question: How many moles of I2 reacted with vitamin C in the Real Lemon sample?
(a) Why is a small amount of MgY2- often added to a water specimen that is to be titrated for hardness? (b) The TI in a 9.76g sample of redenticide was oxidised to the trivalent state and treated with an unmeasured excess of Mg/EDTA solution. the reaction is TI3 + MgY2- ---> TIY + Mg2+. Titration of the liberated Mg2+ required 13.34mL of 0.03560 M EDTA. Calculate the percentage of TISO4 (504.8 g/mol) in the sample.
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.
