An analytical chemist is titrating of a solution of cyanic acid with a solution of . the of cyanic acid is . calculate the ph of the acid solution after the chemist has added of the solution to it. note for advanced students: you may assume the final volume equals the initial volume of the solution plus the volume of solution added.

The pH of the solution is 12.73

Explanation:

To calculate the number of moles for given molarity, we use the equation:

    .....(1)

Molarity of cyanic acid = 0.8600 M  (Assuming)

Volume of solution = 179.5 mL    (Assuming)

Putting values in equation 1, we get:

Molarity of NaOH = 0.6500 M  (Assuming)

Volume of solution = 274.6 mL    (Assuming)

Putting values in equation 1, we get:

Calculating the remaining moles of NaOH, we get:

Calculating the concentration of NaOH by using equation 1, we get:

Moles of NaOH = 0.02412 moles

Volume of solution = 179.5 + 274.6 = 454.1 mL

Putting values in above equation, we get:

1 mole of NaOH produces 1 mole of sodium ions and 1 mole of hydroxide ions.

We are given:

Putting values in above equation, we get:

To calculate pH of the solution, we use the equation:

Hence, the pH of the solution is 12.73

c) should be the answer.

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.
