Five different solutions were prepared in the laboratory. One was prepared by dissolving 7.1g of sodium hydroxide in enough water to make 200 milliliters of solution. Another was prepared by diluting 100mL of 5.8 molar of sodium hydroxide solution to 500mL. The third solution was prepared by aliquoting 5 mL each from the first two solutions and diluting it with 50mL. The fourth solution was prepared by adding eight and nine-tenths grams of sodium hydroxide with 50 mL sample of the first solution and diluting it to 100mL. For the final solution, 38 mL aliquot from the first solution, 12 ml aliquot from the second solution 19 ml aliquot from the third solution and 41 ml of the fourth solution were mixed. a) Determine the concentration of each solution. b) If the five solutions are titrated to hydrochloric acid, what is the expected amount of one molar acid will five milliliter of each of the solution consume? c) The acid solution is standardized against one gram of sodium hydroxide which consumes 23.8 mL of the acid. Whasis the standardized concentration of the hydrochloric acid? d) Determine the actual amount of acid solution that each of the five-milliliter aliquot consume.
