black coffee has a pH of 5, therefore its H+ concentration is ______ times greater than a solution with a pH of 10.
Tju [1.3M]

Answer:

100,000

Explanation:

pH of coffee = 5

pH of solution = 10

Concentration of H+ ions between successive pH values are in multiples of 10

Hence, the pH difference :

pH of solution - pH of coffee

(10 - 5) = 5

Hence, difference in H+ ions will be :

10^5 = 10*10*10*10*10 = 100,000 times
