question 8\nuse the figure above to answer the following question(s).\nstomach acid ______.\n has a higher concentration of hydrogen ions than car battery acid\n has a lower concentration of hydrogen ions than seawater\n is roughly 10,000 times more acidic than normal rainwater\n is technically not acidic\n is less acidic than lemon juice

Answer

Brief Explanations:

The pH scale is logarithmic, where each unit - change represents a ten - fold change in hydrogen ion concentration. Stomach acid has a pH of about 1 - 2, car battery acid has a pH of about 0, seawater has a pH of about 8, normal rainwater has a pH of about 5 - 6, and lemon juice has a pH of about 2 - 3. A lower pH means a higher concentration of hydrogen ions and greater acidity. Since the pH difference between stomach acid (pH ~ 1 - 2) and normal rainwater (pH ~ 5 - 6) is about 4 units, stomach acid is $10^4=10000$ times more acidic.

Answer:

is roughly 10,000 times more acidic than normal rainwater
