Question
A solution in which [H+] = 1 x 10^ -8 M, the pH is ______ and is ______.*
- 1 point
8, acidic
8, acidic
8, basic
8, basic
Solution
The pH of a solution is calculated using the formula pH = -log[H+]. In this case, [H+] = 1 x 10^-8 M.
Step 1: Substitute the given [H+] into the formula pH = -log(1 x 10^-8)
Step 2: Calculate the log of the hydrogen ion concentration log(1 x 10^-8) = -8
Step 3: Multiply by -1 to find the pH pH = -(-8) = 8
The pH scale ranges from 0 to 14. A pH less than 7 is considered acidic, a pH greater than 7 is considered basic, and a pH of 7 is neutral.
Since the pH of the solution is 8, the solution is basic.
So, the answer is "8, basic".
