In Universal Indicator, borax typically changes to a greenish-blue color. This indicates a pH level around 9-10, which is alkaline.
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.
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.
Depending on the type of soil, the value of pH and the type of pH paper. For an acid soil the pH paper from Merck (art. 9565) this color will be probable green.
Bases turn pH paper blue or purple in color.
An aqueous solution of borax is basic in nature. When litmus paper is dipped into the solution, it will turn blue or remain blue, indicating that it is a base. Litmus paper changes color in response to the pH level of the solution it is placed in.

pH paper will turn red when put in vinegar, indicating that vinegar is acidic.
In Universal Indicator, borax typically changes to a greenish-blue color. This indicates a pH level around 9-10, which is alkaline.
Mauve on the pH paper Merck art. 9565.
This color depends on the pH of the solution.
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.
When acid comes into contact with pH paper, the paper changes color depending on the level of acidity. The paper may turn a different color to indicate the acidity level of the substance being tested.
No change occur.
Coffee has an acidic pH - red with litmus paper.
Depending on the type of soil, the value of pH and the type of pH paper. For an acid soil the pH paper from Merck (art. 9565) this color will be probable green.
