Include as part of your online activity report. All information needed to complete this worksheet can be found in the pre-lab information. Read this introductory material first! Record all values with the correct number of significant figures and units. Place all answers on the line when provided. Show calculations for any numerical answers; work must be shown to receive credit. See any 102 TA via webex if you have any questions. Answer all questions for the following acid-base titration: 25.00 mL of H2SO4 was titrated with 0.1 M NaOH. 22.85 mL of NaOH was needed to reach the endpoint of the titration.
Write and balance the chemical equation that results when sulfuric acid is titrated with sodium hydroxide.
H2SO4 + 2NaOH -> Na2SO4 + 2H2O
Calculate the number of moles of base used in the titration.
Calculate the molarity of the acid. Show all work, including how the units cancel.
