Question

An acidic solution at 25°C will have a hydronium ion concentration ________ and a pH value ________. A)[H₃O⁺] > 1 × 10^-7 M,pH > 7.00 B)[H₃O⁺] > 1 × 10^-7 M,pH < 7.00 C)[H₃O⁺] < 1 × 10^-7 M,pH > 7.00 D)[H₃O⁺] < 1 × 10^-7 M,pH < 7.00

Quizplus · Accepted Answer

An acidic solution is defined as a solution with a hydronium ion concentration greater than the concentration of hydroxide ions. Therefore, [H3O+] > 1 × 10^-7 M. A pH value less than 7.00 indicates an acidic solution. This eliminates choices A and C. Choice D is incorrect because a pH less than 7.00 indicates an acidic solution, which contradicts [H3O+] < 1 × 10^-7 M. Therefore, the only correct choice is B.
