The pH scale ranges from 0 to 14, with lower values being more acidic and higher values being more alkaline. A pH of 4 is considered acidic.
Typically, pH test strips will show various colors for different pH ranges. At a pH of 4, you would expect the test strip to change to a color that represents acidity, often in the yellow to red range.
Therefore, after dipping the paper test strip in orange juice (pH 4), you would likely expect the paper test strip to turn **red**.
