The color of pH paper when dipped in well water depends on the water's pH level. If the well water is neutral, the pH paper will typically turn green, indicating a pH of around 7. If the water is acidic, the paper may turn red, while alkaline water will cause it to turn blue. To determine the exact pH, you would need to compare the color change to a pH scale provided with the paper.
Litmus paper dipped in coke will turn red, indicating that the solution is acidic. This change in color occurs because coke is a carbonated beverage containing phosphoric acid and citric acid.
When dipped in coffee, pH paper will change color based on the acidity or alkalinity of the coffee. If the coffee is acidic, the pH paper will turn a different color than if it is alkaline. This color change indicates the pH level of the coffee.
