Consider the reaction between 50.0mL of 0.200 M sodium hydroxide and 75.0mL of 0.100 M HCl. Which of the subsequent statements is correct?
a) After the reaction, the concentration of Na+ is greater than the concentration of OH-
b) The NaOH is the limiting reactant.
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
