Statement 1: Equal volumes of 0.3 M - H₂SO₄ solution and 0.2 M - H₃PO₄ solution will require the same volume of the same NaOH solution for complete neutralization.
Statement 2: H₂SO₄ is a dibasic and H₃PO₄ is a tribasic acid.
Options:
Answer:
A
Solution:
Equal volumes of NaOH are needed when the two solutions have equal normality. H₂SO₄: 0.3 x 2 = 0.6 N; H₃PO₄: 0.2 x 3 = 0.6 N - equal, so I is correct. II is correct and gives exactly why the normalities match (the basicities 2 and 3 make 0.3 x 2 = 0.2 x 3). Hence (a).
