Ph Scale

The pH Scale is a scale made to show how acidic or alkaline a nerve is. The pH of something is measured with pH constitution which endure vary from wide range paper, which covers all phs, plainly is not as accurate at some others. There be pH papers that get very specific that can stir a range such as 2 or 3 and get much more than precise. The neutral on the scale is 7. Anything that is infra 7 is considered acidic and anything above 7 is considered alkaline. Acidic burdens contain more H+ than OH-.H+ stands for a positively charged hydrogen ion and OH- stands means a negatively charged hydroxide ion. This means something with the pH take aim of 4 is more acidic than something with the pH level of 9. When an acidic mental object is turn up into another substance the original substance turns more and more acidic. The acids result begin to break down the proteins. The opposite happens with an basic substance. The Alkaline has a negative charge so when placed into a substa nce it pushes the substance away and then quickly blends in.The proteins do not get disordered down, they all mix together and become paler. The reason why pH is important in biology is because the pH of a cells interior helps frustrate the cells chemical reactions. The cells in the human body penury to regulate the chemical reactions in order to grow and to survive. For example, urine has the pH level of 6, which is slightly acidic, and blood has the pH level of about 7. 4 which is slightly alkaline. When the pH of blood qualifys it is often caused from a failed kidney function.Humans are not the only thing with pH in them however. All living animals ease up pH inside of them, however our blood pHs and theirs can vary greatly. Animals such as crabs and clams have a acidic blood pH. Others like dogs have a blood that has a pH level that is alkaline. Conclusion After observing the effects of an Alkaline and acidic substance on a neutral substance I am able to conclude that the p H level changes. When an Alkaline substance is added to a neutral substance the pH level rises due to the amounts of OH-.Eventually the pH level did even out. When the alkaline substance is added it also causes the substance to well-to-do color. The Acidic substance has quite the opposite effect. When added to the milk the milks pH level dropped and became acidic. The milk became a grayish color and began to chunk up. Eventually the milks pH level did level off and the milk became more like a liquid again. With this being said when an acidic or alkaline substance is added to something, they not only change the pH level, but also they change the appearance.
