A solution turns methyl orange into yellow. The approximate pH of solution is : \

Options

A. 1.2 - 2.8
B. 3.1 - 4.4
C. 6.0 - 7.6
D. 8.3 - 10.00

Explanation

To determine the approximate pH of a solution that turns methyl orange into yellow, we can follow these steps:

### Step 1: Understand the Indicator
Methyl orange is a synthetic pH indicator that changes color depending on the acidity or basicity of a solution. It is red in acidic solutions (pH < 3.1) and yellow in basic solutions (pH > 4.4).

### Step 2: Identify the Color Change
Since the solution turns methyl orange yellow, this indicates that the solution is basic. Therefore, the pH of the solution must be greater than 4.4.

### Step 3: Determine the pH Range for Yellow Color
Methyl orange transitions from red to yellow between pH 3.1 and 4.4. However, it remains yellow in more basic solutions. Therefore, we need to consider the range of pH values where methyl orange is yellow.

### Step 4: Establish the Basic pH Range
From the pH scale:
- A pH of 7 is neutral.
- A pH greater than 7 indicates a basic solution.

Since methyl orange is yellow in basic solutions, we can conclude that the pH of the solution must be above 4.4, and since it is basic, it is also above 7.

### Step 5: Conclusion
Given that the solution is basic and the color is yellow, the approximate pH of the solution is likely to be in the range of 8.3 to 10.

### Final Answer
The approximate pH of the solution is between 8.3 and 10.
