. 12.75 grams of KOH are diluted to 125.0 ml with water. 10.0 ml of the resulting solution are removed and diluted to a final volume of 250.0 ml. What is the concentration of KOH in the final solution?
2. A 25.0 ml sample of 0.0750 M solution of Ba(OH)2 is titrated with 0.200 M HCl. How many milliliters of the HCl solution are required to reach the equivalence point of the titration?
3. For each of the weak acids listed below, a) write a balanced equilibrium equation showing the dissociation and b) write the equilibrium constant expression and c) give the Ka value (from your lecture note manual). HClO2 (aq) HC7H5O2 (aq) (also written as, C6H5COOH) HIO4 (aq)
4. A 150.0 ml sample of 0.250 M HCN is titrated with 50.0 ml of 0.200 M NaOH. What are the concentrations of HCN and CNï in solution after the neutralization reaction occurs?
