The correct Answer is:
To determine the approximate pH of a solution that turns methyl orange into yellow, we can follow these steps: ### Step-by-Step Solution: 1. **Understand the Color Change of Methyl Orange**: - Methyl orange is a pH indicator that changes color based on the acidity or alkalinity of a solution. - It exhibits a red color in acidic conditions (pH < 3.1) and transitions to yellow in alkaline conditions (pH > 4.4). 2. **Identify the pH Range for Yellow Color**: - The yellow color of methyl orange is observed when the pH is above 4.4. - Specifically, methyl orange turns yellow at a pH of approximately 4.4 and remains yellow until the pH reaches about 3.1. 3. **Determine the Approximate pH**: - Since the solution turns methyl orange yellow, we can conclude that the pH of the solution must be greater than 4.4. - However, since it is not specified to be strongly alkaline, we can estimate that the pH is likely around 4.4 or slightly higher. 4. **Conclusion**: - Therefore, the approximate pH of the solution that turns methyl orange yellow is **greater than 4.4**. ### Final Answer: The approximate pH of the solution is greater than 4.4.
