You have separate solutions of HCl and H2SO4 with the same concentrations in terms of molarity. You wish to neutralize a solutio
sergejj [24]

Answer: Option (A) is the correct answer.

Explanation:

A neutralization reaction is defined as the reaction in which an acid reacts with a base to yield salt and water.

The given reaction will be as follows.

         HCl + NaOH \rightarrow NaCl + H_{2}O

       H_{2}SO_{4} + 2NaOH \rightarrow Na_{2}SO_{4} + 2H_{2}O

Now, if molarity of NaOH = M_{1} and volume of NaOH = V_{1}

Therefore, Molarity of HCl = molarity of H_{2}SO_{4} = M_{2}

     Volume of HCl required = \text{molarity of NaOH} \times \frac{\text{volume of NaOH}}{\text{molarity of HCl}}

                 = \frac{M_{1}V_{1}}{M_{2}}

So, vVolume of H_{2}SO_{4} required = 0.5 x molarity of NaOH x \frac{\text{volume of NaOH}}{\text{molarity of H_{2}SO_{4}}}[/tex]

                       = 0.5 \times \frac{M_{1}V_{1}}{M_{2}}

Hence, volume of HCl = 2 x volume of H_{2}SO_{4}.

Thus, we can conclude that HCl solution would be required more volume (in mL) to neutralize the base.
