A chemist needs to determine the concentration of a sulfuric acid solution by titration with a standard sodium hydroxide solution. He has a 0.1157 M standard sodium hydroxide solution. He takes a 25.00 mL sample of the original acid solution and dilutes it to 250.0 mL. Then, he takes a 10.00 mL sample of the dilute acid solution and titrates it with the standard solution. The endpoint was reached after the addition of 14.02 mL of the standard solution. What is the concentration of the original sulfuric acid solution?

A chemist needs to determine the concentration of a sulfuric
acid solution by titration with a standard sodium hydroxide
solution. He has a 0.1799 M standard sodium hydroxide solution. He
takes a 25.00 mL sample of the original acid solution and dilutes
it to 250.0 mL. Then, he takes a 10.00 mL sample of the dilute acid
solution and titrates it with the standard solution. The endpoint
was reached after the addition of 14.33 mL of the standard
solution. What...

A chemist needs 10 liters of a 25%
acid solution. The solution is to be mixed from three solutions
whose concentrations are 10%, 20% and 50%. How many liters of each
solution will satisfy each condition?
a) Use 2 liters of the 50%
solution.
b) Use as little as possible of the
50% solution.
c) Use as much as possible of the 50%
solution.

Imagine that you are attempting to determine the
concentration of an acid by titration with a solution of sodium
hydroxide with a known concentration, using phenolphthalein as an
indicator. For each of the following sources of error, indicate
whether the calculated concentration of acid would be too
high or too low.
i. An air bubble was present in the tip of the buret before
beginning the titration but was absent at the end of the
titration.
ii. You added too...

As an Analytical chemist, you are
designing a titration experiment to determine formic acid in food
samples (formic acid is used as a preservative and antibacterial
agent). You test your protocol by performing a titration of 100.0
mL of 0.050 M formic acid (FW = 46.03 g/mol) with a 0.10 M sodium
hydroxide standard solution. For formic acid
Ka = 1.80 x 10−4 You can ignore
activity coefficients! (60 points total)
Vb = Volume of base added NOTE: Just providing...

A titration experiment is done with 1.37E-2 M
NaOH to determine the acid concentration in 0.631
L of an unknown acidic solution. It was found that to reach the
equivalence point 12.3 mL of strong base was
needed. What was the pH of the original acidic solution?
