2 Fe(OH);(s) + 3 H,SO,(aq) → Fe,(SO,)3(aq) + 6 H,O(1) a) In the first trial, she attempted to completely neutralize 20.0 mL of a 3.00 M acid solution. What is the minimum mass of the solid that must be added to the acid? b) In the second trial, she wanted to completely react 15.9 grams of the solid with 50.0 mL of an acid solution. Determine the minimum concentration of the acid that would be required.

Question
A student conducts five trials of the reaction between solid iron(III) hydroxide and a sulfuric acid solution of varying concentrations. 2 Fe(OH)3(s) + 3 H,SO4(aq) →Fe,(SO4)3(aq) + 6 H,O(1) a) In the first trial, she attempted to completely neutralize 20.0 mL of a 3.00 M acid solution. What is the minimum mass of the solid that must be added to the acid? b) In the second trial, she wanted to completely react 15.9 grams of the solid with 50.0 mL of an acid solution. Determine the minimum concentration of the acid that would be required. c) In the third trial, 2.50 grams of the solid is reacted to completion with 100.0 mL of an acid solution. During the reaction, the temperature of the solution dropped from 21.0 °C to 18.89 °C. Calculate AH. d) In the fourth trial, 49.6 mL of a 0.500 M acid solution reacted completely with excess solid. Determine the amount of heat transferred during the reaction. e) For the final trial, she combined 1.74 g of the solid with 15.0 mL of a 0.100 M acid solution. Calculate the molarity of the iron(III) sulfate produced. Assume that the addition of the solid to the acid does not significantly alter the volume of the solution.
