A teacher gives her students four different liquids commonly found in the kitchen - vinegar, apple juice, dish detergent, and mi
lk - and pH indicator strips. She asks the students to put the liquids in order from most acidic to most basic. What type of investigation could the students conduct to determine the correct order for the liquids?
Use the pH color scale. It shows acidity level of both acids and bases. You dip one of the pH strips into whatever liquid you choose, and then compare the new color of the pH strip to the colors on the scale. This will tell you the level of acidity. pH scale can be found below. As you can see, the brighter colors are more acidic than the darker and duller colors.
Photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
