1) Zinc reacts with hydrochloric acid according to the reactionequation.How many milliliters of 4.00 M HCl(aq) are required toreact with 5.85 g of an ore containing 44.0% Zn(s) by mass?
2) The amount of I3â€“(aq) in a solution can be determined bytitration with a solution containing a known concentration ofS2O32â€“(aq) (thiosulfate ion). The determination is based on the netionic equation.
2SO2O3(2-)(aq) +I3(-)(aq) --->>> S4O6(2-)(aq) +3I(-)(aq)
Given that it requires 25.6 mL of 0.460 M Na2S2O3(aq) to titratea 10.0-mL sample of I3â€“(aq), calculate the molarity of I3â€“(aq) inthe solution.
