The pH Scale
The pH scale rates from one through fourteen. If something is rated one through six it means this thing is an acid. If something is rated a seven is pure like water. If something is rated eight through fourteen it means it is a base. Another name for a base is an alkaline. An alkaline is a substance that takes hydrogen ions. An acid is something that gives hydrogen ions, because of this balance an acid ends up having more hydrogen ions and bases have more hydroxide ions. A solution that is an acid is acidic, a solution that is a base is an alkaline (Science Buddies).
Vinegar like other acids tastes sour. Strong acids can be harmful to organisms. Stomach acid would eat through the stomach if it were not lined with a layer of mucus. Acids can damage materials, even hard ones such as glass. Acids and bases are important in living things because enzymes can do their job only if there is the right amount of acidity. Every time you digest food, acids and bases work in your digestive system. There is an enzyme called pepsin. Pepsin helps break down proteins in the stomach. The stomach makes a strong acid which allows pepsin to work (CK-12 Biology).
The pH of an organism can be tested using pH strips. It is extremely easy and cheap to measure your pH. pH strips cost about twelve dollars. It is important because it instantly indicates your health level. Healthy blood has a pH level of 7.35. An acidic pH level indicates poor health. You could experience symptoms like low energy, pains and aches, mood swings, worrying and fears, poor sleep, and being over weight. If you have a pH of 4 you're probably seriously sick. You can cure it by eating more alkaline foods I have examples in the picture below. To test your pH take out one. break off a piece of about two inches. You can test your urine on the pH test strip. The color should change. Lastly compare this color with the color of the pH on the test strip box. Lastly read the pH number (How to Measure Your pH with pH test strips).
