Answer:

Solution A is 1,000 times more acidic than Sol. B

Explanation:

for pH values we use scientific notation:

-log10 c (where c is the hydrogen ion concentration) is used to notate pH value (think of it as a unit)

ie:

10^-2 is sol A 10^-5 is sol B

5-2 is 3

10^-3 = 1000

there's a diff of 1,000 between the solutions.

Answer: solution A is more acidic as it closer to 0 on the pH scale.It’s also three times more acidic that solution B as when the [H+] concentration for both solutions is calculated it’s found that solution A is three times more concentrated than solution B.
