EXPERIMENT 13： Extraction: Extraction with acid and alkali Objective 1. To recover the benzoic acid and p-dichlorobenzene from its mixture from its mixture by using acid-alkali extraction. 2. To determine the percentage recovery and melting point of the recovered benzoic acid and p-dichlorobenzene. Introduction Acid-base extraction is a process which purifying the acids and bases from mixtures based on their chemical properties. Acid-base extraction is performed to isolate the compounds and natural

In this experiment spinach‚ DPIP‚ phosphate solutions were placed under various filters and the percent orange light transmittance through the solution was measured to determine the rate of photosynthesis. This experiment was set up to discover how different wavelengths of light affect the rate of photosynthesis in a spinach‚ DPIP‚ phosphate solution. I proposed that the spinach‚ DPIP‚ phosphate solution under no filter‚ and therefore exposed to all light will have a highest percent orange light

experiment‚ trials were conducted to test hypothesis of whether all 40 circular spinach leaves would arise or stay at ground level in differential water temperature’s. Using a fluorescent light source gave us another perspective to keep in mind for it could be an advantage or loss to new current predications.

I) Introduction In this lab‚ a test was conducted to determine how the relative redox activity of chloroplasts from spinach leaves‚ which were performing photosynthesis‚ would change when in the presence or absence of light. To observe these changes in redox activity‚ the chloroplasts were exposed to DCPIP‚ a chemical that changes color according to such activity. By determining the redox activity of the chloroplasts‚ it could then be inferred which chloroplasts were photosynthesizing more actively

In this lab‚ we extracted spinach pigments‚ and analyzed what colors of light these pigments absorb. By using TLC plate‚ hexane and acetone‚ I separated the pigments of spinach‚ and discovered that the main pigments were green and yellow. This works because with different polarities‚ pigments move at different rates. Hexane and acetone were also used to separate chlorophyll and carotene from spinach. Since they are polar‚ they can separate organic and inorganic things. From the experiment‚ I know
