An acid spill occurred at a metal processing plant in which a vat of hydrochloric acid ruptured spilling 30 000 L into the surrounding soils. The acid from a soil sample was extracted and analyzed by titration. A 20.0 mL sample required 16.0 mL of 2.00 mol/L calcium hydroxide solution to undergo neutralization. Calculate the concentration of the acid. Include a balanced equation in your answer.
calculations of the sulfuric acid molarity if your average result from the titration of three 0.350 g samples is 15.72 mL. Please explain your answer in detail (words and calculations).
The first equivalence point for the titration of 0.2567 grams of a weak acid is reached when a volume of 26.80mL of 0.0510 M NaOH(aq) has been added. What is the molar mass of the acid?
