Consider the reaction between 50.0 mL of 0.200 M sodium hydroxide and 75.0 mL of 0.100 M HCl. Which of the following statements is correct? A) The NaOH is the limiting reactant. B) After the reaction, the concentration of Na⁺ is greater than the concentration of OH^-. C) After the reaction, the concentration of Na⁺ is equal to the concentration of Cl^-. D) After the reaction, the concentration of Na⁺ is still 0.200 M because Na⁺ is a spectator ion. E) None of these are correct.
