CHEM 1212 Final QUESTIONS AND ANSWERS | UPDATE | 100% CORRECT | A GRADE Indie, Cate, & Ora tested a new indicator to determine its pH range and color changes. The solution used in the experiment was colorless and acidic at pH 1. They added 2 drops of erythrosine indicator to the solution, which turned orange. This is the initial observation for the pH and color. Next they added NaOH to increase the pH, and recorded the pH and color data below. pH 1 - orange (initial observation) pH 2 - orange pH 4 - red pH 6 - red pH 8 - red What is the pH range of the indicator? - Correct Answer-pH 2-4 Indie, Cate, & Ora tested a new indicator to determine its pH range and color changes.
