The ph of a cup of black coffee is 5 while the ph of glass of tomato juice is 4. comparing the ph of the two liquids, the tomato juice has [h+] than the coffee. a) half as many b) 10 times more c) 10 times less d) 100 times more

The pH scale is a logarithmic scale of acidity based on the concentration of hydronium ions [H3O+]. Each 1 step smaller indicates a ten times increase in [H3O+] concentration; for example, take a solution with a pH of 6, a solution with a pH of 7, and another solution with a pH of 8. The pH 6 solution has a ten times greater concentration of [H3O+] than the pH 7, and a 100 times greater concentration than the pH 8.

This means that the tomato juice with a pH of 4 will have B, ten times the concentration of the coffee with a pH 5.

The molecules contain like 54 of water
