Question

A student carries out the titration of H-SOs with NaOH Sbe finds that it takes 19.87 ml, of 0.2091 MNaOH to reach the endpoint using 15.00 mL of HSO4. Use this information to calculate the molarity of the H:SO Show all work! The balanced equation for this reaction appears below: the H SO Hzso,(aq) + 2 NaOH (aq) → Na,so,(aq) + 2H,O(D 7. PV = nRT R-0.082 l atrnl/molk, latin-760 torr, K-°C + 273 Suppose that 5.168 g of hydrogen peroxide solution is used to perform the experiment when the temperature is 24°C and the barometric pressure is 752.3 torr. The volume of gas collected over water when the reaction is complete is 63.5 mL. What is the mass percentage of H:02 in the solution? Vapor pressure of water at 24°C, PH:O is 22.4 torr.
