Question

Choose the correct statement for a solution with hydronium ion concentration of 2.9x10-4 m, the:___. question 3 options:

a. ph is 5.54 and it's acidic
b. ph is 3.54 and it's basic
c. ph is 5.54 and it's basic
d. ph is 3.54 and it's acidic
e. ph is 3.54 and it's neutral

Answer 1

The pH of the solution with a hydronium ion concentration of 2.9x10⁻⁴ M is 3.54. Since a pH less than 7 is acidic, the solution is acidic. The correct answer is (D) pH is 3.54 and it's acidic.

Step-by-step explanation:

To find the pH of a solution with a hydronium ion concentration of 2.9x10-4 M, we use the formula:

pH = -log[H3O+]

Plugging in the given concentration into this formula, we have:

pH = -log(2.9x10-4)

Calculating this, the pH is approximately 3.54.

Remembering that a pH less than 7 is considered acidic, a pH equal to 7 is neutral, and a pH greater than 7 is basic, we can determine that this solution is acidic.

Therefore, the correct statement is:

• pH is 3.54 and it's acidic
