If the concentration of hydronium ions is known to be 1 × 10^−4 what is the pH of the solution?(1 point) Responses 2.00 2.00 10.00 10.00 4.00 4.00 Impossible to determine.

Answer 1

The pH of a solution can be calculated using the formula:

\[ \text{pH} = -\log[\text{H}_3\text{O}^+] \]

In this case, the concentration of hydronium ions \([\text{H}_3\text{O}^+]\) is given as \(1 \times 10^{-4}\).

Now, we can calculate the pH:

\[ \text{pH} = -\log(1 \times 10^{-4}) = -(-4) = 4.00 \]

Therefore, the pH of the solution is 4.00.
