Explanation:
Litmus paper is used to test the pH balance of a liquid or substance. Most substances are either alkali or acid. Alkaline, or basic, chemicals include baking soda, ammonia and lye. Acidic substances include vinegar, lemon juice and battery acid. Alkalies and acids are at opposite extremes chemically, and will cancel each other out to form a neutral substance when mixed together at equal strengths.
