Purpose: To learn how to titrate‚ and calulate the concentration of an acetiuc acid solution. In this case the concentration of vinegar‚ which is diluted acetic acid. Hypothesis: The sodium hydroxide used in this titration would balance out the acetic acid in vinegar. The phenolpthalein‚ a acid –base color indicator will let us know the vinegar have

the casein protein found in milk. One method of creating this plastic is by adding an acid such as vinegar to the milk‚ and separating the filtrate (the plastic created) from the liquid. This experiment will test if the pH level of an acid effects the amount of plastic produced. This research is important because the world is always needing a more efficient way of producing things. This experiment will help to determine if there is a more efficient way of plastic from milk‚ to suppress the ever-growing
