APFIVE Ocean Acidification and pH Calculation
Ocean acidification leads to increases in hydrogen ion concentration. If the concentration doubles, by approximately how many pH units does the pH decrease? (Recall that $$\log_{10}(2) \approx 0.3$$.)
| Factor | Change Factor |
|---|---|
| Doubling of [H+] | 2 |
A
No change in pH
B
Decrease of 0.3 pH units
C
Decrease of 0.7 pH units
D
