In an acid-base neutralization reaction 38.74 ml of 0.500 m potassium hydroxide (ki) reacts with 50.00 ml of sulfuric acid solution. what is the concentration of the h2so4 solution?

0.19M

Explanation:

Using Molarity equation:

= molarity of acid

= volume of acid

= molarity of base

= volume of base

Thus the concentration of the solution is 0.19M.

Concentration of solution is .

Further Explanation:

Neutralization reaction:

It is the reaction that occurs between an acid and a base in order to form salt and water. It is named so as it neutralizes the excess amount of hydrogen or hydroxide ions present in the solution. An example of neutralization reaction is,

The balanced chemical equation for the neutralization reaction of potassium hydroxide and sulphuric acid solution is as follows:

From the balanced chemical reaction, the reaction stoichiometry between   and is as follows:

The balanced chemical equation shows that 2 moles of reacts with 1 mole of to neutralize the reaction completely.

The volume of given solution of is 38.74 ml and the concentration of is 0.500 M

Calculate the number of moles of   as follows:

Since 2 moles of reacts with1 mole of to neutralize the reaction completely, therefore, the number of moles of  required to neutralize 0.01937 moles of is calculated as follows:

Given volume of is 50 ml.

The concentration of can be calculated as follows:
