A change in pH from 3.0 to 5.0 represents
a 100 fold decrease in acidity.
a 100 fold increase in acidity.
a 10 fold increase in acidity.
a decrease in acidity by a factor of 2.
a 10 fold decrease in acidity.
Homework Answers
We know [H^+] = 10^-pH
At pH = 3.0 :-
[H^+] = 10^-3 M
At pH = 5.0 then [H^+] = 10^-5 M
So concentration of H^+ decreased by 10^-3 M / 10^-5 M = 100 fold.
Correct answer is (a)

How does tower design height (Z) change for 10-fold, 100-fold, and 1000-fold removal of a contaminant?...
How does tower design height (Z) change for 10-fold, 100-fold, and 1000-fold removal of a contaminant? Assume a stripping factor of 3, and that the tower surface areas in each of the three cases are the same (same surface loading rate). Note: you are not to calculate the tower height, you are asked to compare height levels for each log-fold increase in treatment.
6. Between 1751 and 1994, the pH of the ocean changed from 8.25 to 8.14. By 2100, the pH of the ocean is expected to be between 7.64-7.84. Is this an increase or decrease in pH? Does that correspond...

4. The X-fold increase in [AMP] (resulting from a 10% decrease in [ATP]) can be shown to be responsible for about a 9 told increase in flux through glycolysis by its action on phosphofructokinase alone. But a 9-fold increase is still not an -fold increase, so there must be something more to the story. That "something more" includes substrate cycling (see Figure 15-25 in your text). The reaction catalyzed by fructose-1,6-bisphosphatase (FBPase) acts as the reverse direction reaction for the...

Let x be a random variable that represents the pH of arterial plasma (i.e., acidity of the blood). For healthy adults, the mean of the x distribution is μ = 7.4.† A new drug for arthritis has been developed. However, it is thought that this drug may change blood pH. A random sample of 31 patients with arthritis took the drug for 3 months. Blood tests showed that x = 8.4 with sample standard deviation s = 2.7. Use a...
