A student is asked to determine the molarity of a strong base by titrating it with 0.250 M solution of H2SO4. The students is in

Hoochie [10]

<u>Answer:</u> The concentration of hydroxide ions in the strong base solution is 0.625 M

<u>Explanation:</u>

To calculate the molarity of solution, we use the equation:

$\text{Molarity of the solution}=\frac{\text{Moles of solute}\times 1000}{\text{Volume of solution (in mL)}}$ .......(1)

<u>For sulfuric acid:</u>

Molarity of solution = 0.250 M

Volume of solution = (30.00 - 5.00) mL = 25.00 mL

Putting values in equation 1, we get:

$0.250M=\frac{\text{Moles of sulfuric acid}\times 1000}{25.00}\\\\\text{Moles of sulfuric acid}=\frac{0.250\times 25.00}{1000}=0.00625moles$

1 mole of sulfuric acid produces 2 moles of hydrogen ions and 1 mole of sulfate ions

Moles of hydrogen ions = $(2\times 0.00625)=0.0125moles$

Moles of hydrogen ions = Moles of hydroxide ions = 0.0125 moles

Now, calculating the hydroxide ions in the base solution by using equation 1, we get:

Moles of hydroxide ions = 0.0125 moles

Volume of base solution = 20.0 mL

Putting values in equation 1, we get:

$\text{Molarity of }OH^-\text{ ions}=\frac{0.0125mol\times 1000}{20.0}\\\\\text{Molarity of }OH^-\text{ ions}=0.625M$

Hence, the concentration of hydroxide ions in the strong base solution is 0.625 M
