The pH of the solution on the right compared to the solution on the left depends on the acidity or alkalinity of each solution. Generally:

• If the solution on the right turns an indicator a color associated with a higher pH (e.g., blue for litmus), it is more alkaline (higher pH) than the solution on the left.
• If it turns the indicator a color associated with a lower pH (e.g., red for litmus), it is more acidic (lower pH) than the solution on the left.
• If both solutions produce the same indicator color, their pH values are similar or equal (neutral pH is 7).

Since pH is a logarithmic scale measuring hydrogen ion concentration, even small differences in pH indicate significant differences in acidity or alkalinity

. Without specific color or pH values for the solutions on the right and left, the exact comparison cannot be determined. However, if the right solution's indicator color corresponds to a pH higher than the left, it is less acidic (more basic), and vice versa

. In summary, the pH of the solution on the right is either higher, lower, or equal to that of the solution on the left depending on the indicator color change or measured pH values. The pH scale is used to compare such differences quantitatively
