Choose the correct statement. A)30 mL of 2 molar H₃PO₄(aq)will exactly react with 15 mL of a 2 molar NaOH(aq)solution. B)One liter of 1 molar HCl(aq)will exactly neutralize 2 liters of 0.5 molar NaOH(aq). C)A 1 molal solution always contains exactly 1 mole in a liter of solution. D)One liter of a 1 molar solution of an acid always exactly neutralizes one liter of a one molar solution of a base. E)A 1 molar solution requires 2 moles of H₂SO₄(aq)per liter of solution.

Question

Quizplus · Accepted Answer

This statement follows the concept of equivalent equivalents in acid-base neutralization reactions. One liter of 1 molar HCl contains 1 equivalent of acid, which will exactly neutralize 2 equivalents of base in 2 liters of 0.5 molar NaOH solution. The other statements contain errors, such as incorrect molarity or mole ratios, or use of an undefined compound.
