A solution contains 43 mEq/L of of Cl^- and 11 mEq/L of HPO₄^-2 .If the only cation in the solution is Na⁺ ,what is the Na⁺ concentration in mEq/L? A)43 mEq/L B)11 mEq/L C)54 mEq/L D)32 mEq/L E)2.0 mEq/L

Question

Quizplus · Accepted Answer

Since the charges of the anions Cl^- and HPO₄^-2 are not given, we cannot directly add their concentrations. However, we know that the only cation in the solution is Na⁺. Therefore, the total positive charge in the solution must be equal to the total negative charge. Let x be the concentration of Na⁺ in mEq/L. Then we can set up the equation: 43 - x = -11 Solving for x, we get: x = 54 Therefore, the concentration of Na⁺ in the solution is 54 mEq/L, which is choice (C).
