If HCl is a 0.05 M solution and 50 mL is used to titrate the NaOH, what is the molarity of NaOH if the flask contains 100 mL?

Molarity of NaOH = 0.025 M

Explanation:

Given dа ta:

Molarity of HCl = C₁ = 0.05 M

Volume of HCl = V₁ = 50 mL

Molarity of NaOH = C₂=?

Volume of NaOH = V₂ = 100 mL

Solution:

Formula:

C₁V₁ = C₂V₂

C₁ = Molarity of HCl

V₁ = Volume of HCl

C₂ = Molarity of NaOH

V₂ = Volume of NaOH

Now we will put the values:

C₁V₁ = C₂V₂

0.05 M * 50 mL = C₂ * 100 mL

2.5 M. mL = C₂ * 100 mL

C₂ = 2.5 M. mL / 100 mL

C₂ = 0.025 M
