* pH paper reacts to acidity and alkalinity, not specific substances. Tea contains various compounds that influence its overall pH, but pH paper doesn't tell you what those compounds are.
* Tea's pH varies. The pH of tea can range from slightly acidic to slightly alkaline depending on the type of tea, brewing method, and other factors.
* Color change is subjective. Even if you get a color on the pH paper, the specific color might not match perfectly with the pH scale due to variations in the paper and lighting.
Instead of relying on pH paper, you could:
* Use a digital pH meter. These are more accurate and reliable for determining the exact pH of your tea.
* Consult a tea guide. Many resources provide information about the typical pH ranges for different types of tea.
Ultimately, it's more about understanding the factors that affect tea's pH rather than trying to get a specific color on pH paper.
