V 1 m L of NaOH of molarity X and V 2 m L of B a ( O H ) 2 of molarity Y are mixed together. The mixture is completely neutralized by 100 mL of 0.1N HCl. If V 1 / V 2 = 1 / 4 and X/Y = 4 then what fraction of acid is neutralized by B a ( O H ) 2

Question

V 1 m L of NaOH of molarity X and V 2 m L of B a ( O H ) 2 of molarity Y are mixed together. The mixture is completely neutralized by 100 mL of 0.1N HCl. If V 1 / V 2 = 1 / 4 and X/Y = 4 then what fraction of acid is neutralized by B a ( O H ) 2, 0.5, 0.25, 0.33, 0.67

MARKS App · Accepted Answer

M e q . of NaOH + Meq. of Ba ( OH ) 2 = M e q . of HCl X . V 1 + 2 Y . V 2 = 100 × 0.1 = 10 or 4 Y . V 2 4 + 2 Y . V 2 = 10 or 3 Y V 2 = 10 2 Y . V 2 = 10 × 2 3 = 6.66 Fraction used by B a ( O H ) 2 = 6.66 10 = 0.67
