A solution for which [H⁺] = 1.0 *10^-³ will have a pH of _____ . A) 5.00 B) 3.00 C) (-5.00) D) (-9.00)

Question

Quizplus · Accepted Answer

The given equation represents a weak acid-base reaction. H^{represents the weak acid (HA) and} represents its conjugate base (A-). F1F1F1S1 represents a common ion that will shift the equilibrium towards the side of the weak acid (Le Chatelier's principle). Therefore, the pH of the solution will be less than 7. Looking at the answer choices, only option B (pH = 3.00) satisfies this condition.
