3. What is the concentration of all ionic species present when 100. mL of 0.200 M NH4OH and 100. mL of 0.200 M H2SO4 are mixed.
4. Determine the mass of CuS formed when 100. mL of 0.100 M H2S and 50.0 mL of 0.150 M Cu(C2H3O2)2 are reacted. What is the concentration of C2H3O2- in the resulting solution?
5. 18.0 g of zinc is added to 100. mL of 0.200M HBr.
a) Will all of the zinc dissolve?
b) What will be the concentration of Br- in the resulting solution(after any reaction takes place)?
6. A 1.25 g sample of impure sodium carbonate requires 18.20 mL of 0.480 M HCl to become completely neutralized. What is the percentage of the sodium carbonate in the original sample?
7. 35.0 mL of 0.325 M AgNO3 is added to 50.0 mL of 0.125 M MgCl2. Assuming all volumes are additive, what will be the molarity of all ions in the solution after mixing and after any reaction takes place?(AgCl is not present as ions since it is insoluble.)
