Determining the Molarity of Nitric Acid Solution
What is the molarity of the nitric acid?
A 45.0 ml sample of nitric acid is neutralized by 119.4 ml of 0.2 M NaOH.
Answer
The molarity of the nitric acid is 0.53 M.
The process of determining the molarity of a nitric acid solution involves utilizing the dilution formula. The dilution formula is given as:
C1V1 = C2V2
Where:
C1 = initial concentration of the acid
V1 = initial volume of the acid
C2 = final concentration of the acid
V2 = final volume of the acid
Given the parameters:
V1 = 45 mL
C2 = 0.2 M
V2 = 119.4 mL
Substitute the given parameters into the dilution formula:
C1 = (C2V2) / V1
C1 = (0.2 x 119.4) / 45
C1 = 23.88 / 45
C1 = 0.53 M
Hence, the molarity of the nitric acid solution is 0.53 M.
