Question

Determine the Molar Concentration of an Acid Solution

1. Unknown Acid Sample code: F F

2. Balanced equation for neutralization of acid with NaOH: NAOH

3. Data Table:                                                                               Trial 1      Trial 2     Trial 3

Volume of acid solution (mL)                                                          25.0             25.0         25.0

Buret Reading: Initial Volume of NaOH (mL)                                2.90              13.00         23.00

Instructor’s signature

Buret Reading: Final Volume of NaOH (mL)                                   13.00              23.00            32.80

Volume of NaOH dispensed (mL)?

Average molar concentration of NaOH (mol/L), Part A                             0.1978

Mols of NaOH dispensed (mol)?

Molarity of acid solution (mol/L) (For accurate work, the three molarities should be within 1 %.) ?
