Answer

Explanation:

Step1: Analyze pH = 8.5

A pH of 8.5 indicates a basic solution.

Step2: Analyze pH > pOH

In water - based solutions at 25°C, pH + pOH=14. If pH > pOH, then pH>7, indicating a basic solution.

Step3: Analyze meter reading of 9.26

A pH meter reading of 9.26 indicates a basic solution.

Step4: Analyze litmus - paper test

Litmus paper turning blue indicates a basic solution.

Step5: Analyze phenolphthalein test

Phenolphthalein is color - less in acidic and neutral solutions and turns pink in basic solutions. The statement only mentions adding phenolphthalein but does not give the color change result, so it is different from the others which clearly indicate a basic solution.

Answer:

After adding phenolphthalein.
