A surface water sample of 50 ml was taken to determine the
concentration of an organic pollutant in the sample. An organic
solvent was used as extracting solvent. On analysis of both phases
by GC-MS, the pollutant concentration (mass/vol based) in the
organic phase was 5 times that found in the aqueous phase. If after
the second extraction (each using 50ml fresh organic solvent) the
concentration of pollutant in the organic phase was 18 ppm (mass
basis), determine the initial...

The pH of a liquid is a measure of its acidity or alkalinity.
Pure water was a pH of 7, which is neutral. Solutions with a pH
less than 7 are acidic while solutions with a pH greater than 7 are
alkaline. A biologist was interested in testing the purity of lake
water in Florida. A random sample of 59 lakes was taken, and the pH
of water in each lake was recorded. The sample of lakes had an
average...

Please answer all questions
pH in Water:
The acidity of alkalinity of a solution is measured using pH. A
pH less than 7 is acidic; a pH greater than 7 is alkaline. The
following data represent the pH in samples of bottled water and tap
water.

(a) Sketch the titration curve for an alkalinity test in which
the water sample had an initial pH of 6.35. In that test, 15 mL of
0.1 N acid was added to a 150-mL sample.
(b) Calculate the alkalinity in meq/L and mg/L as
CaCO3. Answer: 10 meq/L, 500 mg/L as
CaCO3
I know the answer is correct but I am having a
problem on a few of the steps, please show all work for a "thumbs
up"! Thanks!
