Question

A 0.500M solution of Hcl is titrated with a 0.250M aqueous solution of sodium hydroxide. The neutralization of hydrochloride acid with sodium hydroxide produces an aqueous solution of sodium chloride at the equivalence point. What is the concentration of sodium chloride at the equivalence point? Options a 0.500M b 0.250 M c. 0.375M d. 0.750M e 1.000M

Answer 1

A:- Balanced chemical equation for this reaction is as follows,

     HCl +   NaOH     -------->     NaCl     +    H2O

   1 mole     1 mole                    1 mole

That means at equalence point 1 mole of HCl completely consumed with 1 mole NaOH, as a result 1 mole of NaCl is formed. From the standard data, when 0.500 M HCl titrated with 0.250 M NaOH which produces 0.250 M NaCl.

A:- b. 0.250 M
