The bulge is often part of your intestine, but it may also be tissue or fat. There are three common types of ventral hernias. An incisional hernia occurs where you have had a surgical cut. An epigastric hernia occurs above your belly button. A spigelian hernia occurs on the side of your abdomen.
Acids are compounds that dissociate (break) into hydrogen (H+) ions and another compound when placed in an aqueous solution. Remember that acetic acid example? Bases are compounds that break up into hydroxide (OH-) ions and another compound when placed in an aqueous solution.
There is a scale for acids and bases just like everything else. Here are a couple of definitions you should know: Acid: A solution that has an excess of H + ions. It comes from the Latin word acidus, which means sharp or sour. Base: A solution that has an excess of OH-ions. Another word for base is alkali. Aqueous: A solution that is mainly water. Think about the word aquarium. AQUA means water. Strong Acid: An acid that has a very low pH (0-4). Strong Base: A base that has a very high pH (10-14). Weak Acid: An acid that only partially ionizes in an aqueous solution. This means that not every molecule breaks apart. Weak acids usually have a pH close to 7 (3-6). Weak Base: A base that only partially ionizes in an aqueous solution. This means that not every molecule breaks apart.
