From the graph I can clearly see that Distilled water has a much larger concentration of water then the cell sap in the potato tissue. I can make this conclusion because the results show a big increase in weight of the potato piece. Meaning that water has moved from outside the potato into the potato due to Osmosis‚ proving that the distilled water had a higher concentration of water‚ as water moves from a high concentration to a low concentration. I can also see that the glucose

Chemical Separation Introduction: The objective of this experiment was to extract the pigments from spinach leaves‚ perform Thin Layer Chromatography (TLC) on the spinach leaf extract‚ and then determine the best solvent mixture to use to separate the pigments in the extract. The pigments are located inside the chloroplast walls in the cells of the spinach leaves. In order to obtain the pigments the cell walls must be broken down thus exposing the pigment containing chloroplasts. Upon

Purpose: To Inform Topic: Chemical Warfare Intro 1) Chemical weapons are extremely toxic chemicals which differ from explosive weaponry. Middle ages and renaissance are documented to have used poisonous chemicals on individuals. Chemical warfare is use of chemical agents to kill or incapacitate the enemy. 2) Today I will inform you of different chemical agents. Since World War I‚ several types of agents have been developed into weapons. These chemical weapons include (I) Choking

the unknown sample. Since the hardness of water arises from the presence of metal ions‚ we can use disodium salt of EDTA and the indicator Eriochrome Black T to determine the concentration of M 2+ ( Mg 2+ or Ca 2+) metal ion impurities. Chemical principle or theory involved in this lab: To determine waters hardness we will use a technique called a chelometric titration. “When a neutral molecule or anion (lewis base) donates electron pairs and attaches itself to a metal ion center (a
