Which indicator is yellow in a solution with a pH of 9.8? A solution with an unknown pH is tested with phenolphthalein and turns bright pink. Is this solution acid, basic, or neutral? Another solution of unknown pH is added to the bright pink solution. As the solution is added, the original solution turns from bright pink to clear. How would you classify the pH of the solution being added?
