- Walter White requires a sulfuric acid (Strong acid) solution to use in a very important synthetic reaction. He finds a bottle labeled H2SO4, but by some strange turn of events, he cannot remember the concentration. He decides to perform a titration to determine the concentration of the H2SO4. He pours 22.20 mL of his unknown sulfuric acid solution into a flask and finds that it requires 29.50 mL of 0.57 M KOH (strong base) to reach the endpoint. What is the concentration of Walter White's sulfuric acid solution? (Enter your numeric answer only, do not use scientific notation, enter 2 decimal places with your answer) For reference: KOH = 56.106g/mol H2SO4= 98.079g/mol Avagadro's number 6.022x1023arrow_forwardPrior to dissolving KHP, you are instructed to boil the distilled water. By boiling the water, you are removing CO2, and thus carbonic acid, from the solution.
