n acid with a pKa of 8.0 is present in a solution with a pH of 6.0. What is the ratio of the protonated to the deprotonated form

Nady [450]

Answer : The ratio of the protonated to the deprotonated form of the acid is, 100

Explanation : Given,

$pK_a=8.0$

pH = 6.0

To calculate the ratio of the protonated to the deprotonated form of the acid we are using Henderson Hesselbach equation :

$pH=pK_a+\log \frac{[Salt]}{[Acid]}$

$pH=pK_a+\log \frac{[Deprotonated]}{[Protonated]}$

Now put all the given values in this expression, we get:

$6.0=8.0+\log \frac{[Deprotonated]}{[Protonated]}$

$\frac{[Deprotonated]}{[Protonated]}=0.01$

As per question, the ratio of the protonated to the deprotonated form of the acid will be:

$\frac{[Protonated]}{[Deprotonated]}=100$

Therefore, the ratio of the protonated to the deprotonated form of the acid is, 100

FOR 99 POINTS WILL MARK BRAINLIEST If a person has clogged arteries and high blood pressure, his or her doctor might recommend a

Vladimir79 [104]

If the person had clogged arteries and high blood pressure, then went on a healthy diet, the person would start losing weight. They would have a more stable blood pressure (since they are eating healthy foods, with less saturated fat) and the clogged arteries would look significantly better. He/she might lose her/his risk of developing diabetes, heart disease, cancer, etc. Most of her/his health issues would start to balance out if they started eating a diet low in saturated fat.

I hope this helps!
