I need help with this question on redox titrations. It says that a 10.00mL sample of an aqueous solution of hyrdrogen peroxide, H_2O_2(aq) is treated with an excess of KI(aq). The liberated I_2 requires 28.92 mL of 0.1522 M Na_2S_2O_3 for its titration. Is the H_2O_2(aq) up to its full strength (3% H_2O_2 by mass) as an antiseptic solution? Assume that the density of the aqueous solution of H_2O_2 is 1.00g/mL. Thank you!
