Question
Give the pH of a strong base and an example
Answers
GPT-4o mini
A strong base typically has a pH of 13 to 14. The exact pH can vary depending on the concentration of the base in solution.
An example of a strong base is sodium hydroxide (NaOH). When dissolved in water, it completely dissociates into sodium ions (Na⁺) and hydroxide ions (OH⁻), resulting in a high concentration of hydroxide ions and therefore a high pH. For instance, a 0.1 M solution of NaOH would have a pH of approximately 13.
In summary:
- **Strong Base:** Sodium Hydroxide (NaOH)
- **Approximate pH:** 13-14 (depending on concentration)
