What volume (in mL) of 0.750 M sodium hydroxide is needed to neutralize (react with) 275 ml of 0.500 M sulfuric acid (H2SO4)?
NaOH + H2SO4 -> H2O + Na2SO4

Respuesta :

We know the formula

  • C1V1=C2V2

C is concentration and V is volume

  • 0.750V1=275(0.5)
  • 0.75V1=137.5
  • V1=183.34mL

The new volume will be by using the relation between molarity and volume formula.

What is molarity?

Molarity, also termed as molar concentration in a solution, is a method of determining how much material is present in a chemical solution.

Calculation of volume with the aid of molarity formula is shown below:

Volume is calculated by using the molarity formula.

[tex]M_{1} V_{1} = M_{2} V_{2}[/tex]

Where, M is molarity and V is volume.

It is given that, [tex]M_{1}[/tex] = 0.750 M , [tex]M_{2}[/tex] = 0.500 M, [tex]V_{1}[/tex] = 275 ml .

Now, put the value of given data in molarity formula.

[tex]M_{1} V_{1} = M_{2} V_{2}\\V_{2} = M_{1} V_{1} / M_{2}\\V_{2} = (0.750 M) (275 ml) / 0.500 M\\V_{2} = 183.34 ml[/tex]

Therefore, the volume will be 183.34 ml.
