what is the pH of a solution prepared from solid, neutral 2-nitrophenol providing a fromal concentration of 0.0353M, given that

REY [17]

Answer:

pH = 4.34

Explanation:

pH= -1/2(logKa) -1/2(log C)

= -1/2( log 5.98*10^-8) -1/2(log 0.0353)

=-1/2(-7.22)-1/2(-1.45)

=3.61+0.725= 4.34

Suppose that 0.25 mole of gas C was added to the mixture without changing the total pressure of the mixture. How does the additi

Yanka [14]

Here we have to get the effect of addition of 0.25 moles of gas C on the mole fraction of gas A in a mixture of gas having constant pressure.

On addition of 0.25 moles of C gas, the mole fraction of gas A will be $\frac{moles of gas A}{moles of gas A + 0.25}$ .

The partial pressure of gas A can be written as $P_{A}$ = $x_{A}$ ×P (where $x_{A}$ is the mole fraction of gas A present in the mixture and P is the total pressure of the mixture.

The mole fraction of gas A in a mixture of gas A and C is = $\frac{moles of gas A}{moles of gas A + moles of gas C}$ and $\frac{moles of gas C}{moles of gas A + moles of gas C}$ respectively.

Thus on addition of 0.25 moles of C gas, the mole fraction of gas A will be $\frac{moles of gas A}{moles of gas A + 0.25}$ .

Which is different from the initial state.
