Examples of acids and bases
- Examples of acids: citric acid found in some fruits and vegetables, especially citrus, ascorbic acid, a vitamin C, and vinegar that contains% ratio 5 of acetic acid, carbonic acid used in the carbonation soft drinks, lactic acid in milk,  tartaric acid Protein content in the tamarind, and stomach produces hydrochloric acid, which helps to digest food. 
- Examples of rules: detergents, soaps, sodium hydroxide, ammonia and household water,  and baking soda, toothpaste that works to neutralize existing acid in the mouth and prevent tooth decay. 
Can pH is defined as a measure of the amount of acidity or alkalinity in the solution, and if the pH of the solution is equal to the number 7, it is considered loosed neutral, and if the pH is less than the number 7 of the solution it is loosed acidic, and if the pH is greater than the number 7 shall be deemed The solution loosed based cattle.
