Alkaline is a substance that is over the pH of 7. an acid is a substance that is lower than the pH of 7

The same will happen if litmus paper is used instaed. If the paper turns blue/purple/black it means that the substance is an alkaline. If the paper turns red/orange/yellow it means that the substance is an acid
If the substance or the litmus paper turns green it means that it is neutral (It has the pH of 7)
