Methyl red is typically used in pH tests to determine if a solution is acidic (pH<4.4), while phenol red is typically used to approximate the pH of a solution (between pH 6.8-8.4). Use methyl red when you need to indicate a more acidic pH level, and phenol red for a broader pH range closer to neutral.
Grapes can contain a high concentration of tartaric acid, which give them among the highest acid content in fruits. The pH of concord grapes is in the range 2.8 to 3.0, compared to higher than 3.0 for orange juice. Tokyo grapes are among the least acid at a pH above 3.3. See Related Links
