Answer to Question #64831 in General Chemistry for Theo Brownswood

Question

2) How will each of the following sources of error affect ( increase or decrease ) the computed concentration of the NaOH solution?

a) The acid burette is contaminated with a basic solution.
b) the is air at the tip of the base burette before titration.
c) a small amount of the acid solution was spilled while transferring it to the erlenmeyer flask.

3) What is the concentration ( in molarity ) of a 250.0 mL CH3COOH solution that requires 30.50 mL of the NaOH solution used in this activity?

Answer 1

Solution: 2) Alkalimetry is a version of titration – a common laboratory method. The concentration of base compute by equation:
