A solution has a pH of 8.4. what is the H + concentration of the solution?

A solution has a pH of 11. What is the H + concentration of the solution? Is the solution an acid or base?

Your father goes to the store to buy cleaner to remove such deposits from your bathtub. He has a choice between a product containing lemon juice (H + = 10^-2.5M) and one containing vinegar (H + = 10^ - 3.3M) which product would you recommend he purchase and why?

[H+]=3.98x10^-9

[H+]=10^-pH=10^-8.4

[H+]=10^-11, base

[H+]=10^-pH=10^-11

A solution with a pH of more than 7 is basic.

Lemon juice because it is more acidic

pH of lemon juice: 2.5

pH of vinegar: 3.3

Since the pH of lemon juice is lower, it is more acidic and will be more effective at removing the basic deposits.
