For a solution labeled "0.10 M H₃PO₄(aq)," A) [H₂PO₄^?] is greater than 0.10 M. B) [H⁺] = 0.30 M. C) [PO₄³^-] = 0.10 M. D) [H⁺] = 0.10 M. E) [H⁺] is less than 0.10 M.

Question

Quizplus · Accepted Answer

The solution is labeled as a 0.10 M concentration of H₃PO₄(aq), which means that this is the concentration of that specific species in solution. None of the other species' concentrations are given, so we cannot make any conclusions about them. Therefore, the only safe choice is that [H⁺] is less than 0.10 M.
