Chapter 10: Q7TY (page 223)

The both $^{[H_{2} A] = [H A^{‐}]}$ are equal as found to be $^{pH = 10.54}$

Short Answer

Expert verified

The both $^{[H_{2} A] = [H A^{‐}]}$ are found to be equal $^{pH = 10.54}$

Step by step solution

Definition of Henderson-Hassel Balch equation

The Henderson Hasselbalch equation approximates the link between a solution's pH or pOH, its pKa or pKb, and the ratio of dissociated chemical species concentrations.

Determine the both are equal as found to be

The both $^{[H_{2} A] = [H A^{‐}]}$ are equal, and the pH must be determined.

Henderson-Hassel Balch equation

$pH = {pK}_{1} + \log \frac{[H A^{-}]}{[H_{2} A]} pH = {pK}_{2} + \log \frac{[A^{2}]}{[H A^{-}]}$

The negative logarithm of Hydrogen ion activity can be calculated using the equation above.

It are aware of this.

The purity of the intermediate species' pH, $^{H_{2} {Arg}^{+}}$

Arginine is a kind of amino acid $^{[{Arg}^{-}]}$ at $^{{pK}_{3} = 12.1}$ is 4.00

$H_{2} {Arg}^{+} \approx \frac{1}{2} ({pK}_{1} + {pK}_{2}) = 5.40$

$^{pH = 10.54}$ (and a pH exceeding $^{= {pK}_{2}}$ )

Therefore $^{[H_{2} {Arg}^{+}] = [{Arg}^{-}]}$ at $^{pH = 10.54}$

Both of them $^{[H_{2} A] = [H A^{‐}]}$ are found to be equal $^{pH = 10.54}$ .
