97. because atoms, molecules, and ions are very small, they are counted in units of moles, where 1 mole = 6.022 × 1023 molecules. concentration of ions in a liquid is measured in units of moles per liter. the measure of the acidity of a liquid is called the ph of the liquid and is given by the formula
ph = −log(h),
where h is the concentration of hydrogen ions in units of moles per liter.
c. suppose that liquid a is more acidic than liquid b, and their ph values differ by 1.2. what is the ratio of the concentration of hydrogen ions in liquid a to the concentration of hydrogen ions in liquid b?

15.85

Step-by-step explanation:

If A is more acidic than B, so (pH)B > (pH)A, because -log[H⁺] decreases when [H⁺] increases, as demostrated in the graph below. So:

(pH)B - (pH)A = 1.2

-log[H⁺]B -(-log[H⁺]A) = 1.2

-log[H⁺]B + log[H⁺]A = 1.2

log([H⁺]A/[H⁺]B) = 1.2 (propertie of logaritim)

[H⁺]A/[H⁺]B =

[H⁺]A/[H⁺]B = 15.85

it is a function because for every x value there is only one y value

for every x value there is only one y value
