Five different solutions were prepared in the laboratory. One was prepared by dissolving 7.1 g of sodium hydroxide in enough water to make 200 milliliters of solution. Another was prepared was diluting 100 mL of 5.8 molar solution os sodium hydroxide solution to 500 mL. The third solution was prepared by aliquoting 5 mL each of the from the first two solutions and diluting it with 50 mL. The fourth was prepared by adding eight and nine-tenths grams of sodium hydroxide with 50 mL sample of the first solution and diluting it to 100 mL. 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. Determine the concentration of each solution. 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? The acid solution is standardized against one gram of sodium hydroxide…
