Question

0.01 M KMnO_4 solution was added to 20.0 mL of 0.05 M Mohr's salt solution through a burette. The initial reading of 50 mL burette is zero. The volume of KMnO_4 solution left in the burette after the end point is_______mL. (nearest integer)

Accepted Answer

Correct answer: 30. (30) Sol. N_1 V_1 = N_2 V_2 0.01 x 5 x V_1 = 0.05 x 1 x 20 V_1 = 20 ml used ∴Volume left = 50 - 20 = 30 ml

$0.01 M K M n O_{4} solution was added to 20.0 mL of 0.05 M Mohr's salt solution through a burette. The initial reading of 50 mL burette is zero. The volume of K M n O_{4} solution left in the burette after the end point is_______mL. (nearest integer)$
