![**Question**: Calculate the concentration of H₃O⁺ in a solution that contains 5.5 × 10⁻⁵ M OH⁻ at 25°C. Identify the solution as acidic, basic, or neutral.
**Answer Options**:
- 9.2 × 10⁻¹ M, basic
- 9.2 × 10⁻¹ M, acidic
- 1.8 × 10⁻¹⁰ M, basic
- 1.8 × 10⁻¹⁰ M, acidic
- 5.5 × 10⁻¹⁰ M, neutral
**Explanation**: To solve this problem, use the relation between hydronium ions (H₃O⁺) and hydroxide ions (OH⁻) concentrations in water at 25°C, given by the ion product of water (Kw):
\[ \text{Kw} = [\text{H₃O⁺}][\text{OH⁻}] = 1.0 \times 10^{-14} \]
From this, you can calculate \([\text{H₃O⁺}]\) as:
\[ [\text{H₃O⁺}] = \frac{1.0 \times 10^{-14}}{[\text{OH⁻}]} = \frac{1.0 \times 10^{-14}}{5.5 \times 10^{-5}} \]
Calculate the concentration to find the correct option and determine if the solution is acidic, basic, or neutral based on the concentration of H₃O⁺.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F1c6de790-3967-4822-b83d-f877aa472903%2F2252bf2b-fc8e-4213-996c-ea53225c154d%2Fbbxs5fd_processed.png&w=3840&q=75)
