amount of acid in our stomachs. This excessive acid production results in the unpleasant symptoms of heartburn and may contribute to the formation of ulcers by irritating the stomach lining. To relieve such symptoms we often use antacids. Antacids are bases (most commonly bicarbonates‚ carbonates and hydroxides) that are used to neutralize the excess stomach acid. Fluid magnesia was invented in 1817 by the Irish pharmacist Sir James Murray (1788–1871). Murray built a plant to produce a mixture of magnesium

buffer solutions are commonly made from a weak acid and one of its salts often sodium salt. An alkaline buffer solution has a pH greater than 7. Alkaline buffer solutions are commonly made from a weak base and one of its salts. When hydrogen ions are added to a buffer‚ they will be neutralized by the base in the buffer. Hydroxide ions will be neutralized by the acid. These neutralization reactions will not have much effect on the overall pH of the buffer solution. A. Molarity Molarity is another

that work by increasing the stomach’s pH balance and quickly relieving the symptoms associated with heartburn and indigestion. The pH system is a scale for measuring how acid or base is a given environment or substance. The scale goes from 0 to 14 with a pH of 7 being neutral‚ below 7 is acidic and above 7 is alkaline or base. Normally‚ the acid level in the stomach is about 2 or 3. Trouble may start when the pH drops below those numbers. An effective antacid neutralizes just enough excess acid to alleviate
