Correct answer and explanation

Correct answer: > 7

Explanation: āœ… Correct Answer: C) > 7 šŸ“š Explanation: The pH scale measures the relative acidity or alkalinity of a chemical solution. A pH value of exactly 7 indicates a neutral state, while any value greater than 7 ($> 7$) identifies an alkaline or basic solution. Strong bases like sodium hydroxide exhibit pH values closer to 14. This scale is logarithmic, meaning each whole number change represents a ten-fold change in hydrogen ion concentration.
