Instruction: Give the derived formula,
substitute the given in the formula and write the final
answer with proper unit & correct no.
Use the following formula:
1. C1V1 = C2V2 2. Nacid x Vacid = Nbase x Vbase 3. %analyte =
Ntitrant x Vtitrant x EqWt Analyte x 100%
wt. of sample
Problem:
1. What is the N of an HCl solution if 45.23 mL of it is
required to titrate a 0.2505 sample of Na2CO3?
2. A sample of soda ash (impure Na2CO3) is titrated with 0.5000 N
H2SO4. If the sample weighs 1.1000 g and
requires 35.00 mL of the acid for complete neutralization, what is
the %Na2CO3 in the ash assuming no other
active component is present?
