preciously add 25.00 mL of diluted bleach (from step 2) to the reaction flask. Using a 100-mL graduated cylinder‚ add about 15 mL of distilled or deionized water to the reaction flask. Used a 100-mL graduated cylinder‚ add about 20 mL of 10% potassium iodide solution to the reaction flask. This 10% KI solution should be clear‚ and not yellow. Pour about 2 mL of starch solution in a 10-mL graduated cylinder and place the cylinder next to the reaction flask. This starch solution will be added to the flask

movement from higher to lower concentration or lower to higher concentration is called hypotonic solution and hypertonic solution. Hypothesis: My Hypothesis for diffusion that the starch solution will be hypotonic and diffuse into potassium iodide (IkI). Hypothesis for osmosis is that each of the individual dialysis bags will increase because of the different concentration of the solutions. Which makes this and hypotonic experiment. Hypothesis for this experiment is that each of the four

potassium permanganate. 5. Add drops of potassium permanganate to the solution that changed color in the previous step. Record how many drops were added until the purple color of the ion no longer changed. 6. Observe color changes when sodium iodide solution is reacted with chlorine water and bromine water (separately). 7. Observe color changes when sodium bromide solution is reacted with chlorine water and iodine solution (separately). 8. Observe what happens when 3M sulfuric acid

Explain your answer. Yes‚ because it restricted certain molecules or particles to diffuse through its microscopic holes. Based on the tiny size of the holes‚ water and glucose were small enough to fit through them‚ whereas starch and potassium iodide weren’t able to diffuse through. 4. In part B‚ what caused the mass of the dialysis bags to change? Was there more or less water in the dialysis bags at the conclusion of the experiment?

Chronic Disease‚ Asthma Good morning to our beloved lecturer and my fellow classmate. In our advanced world nowadays‚ we have discovered about lots kinds of diseases. Among those diseases that have been discovered is asthma. Generally‚ we knew that asthma is a lung-related disease and it does make breathing become difficult. But did you know that asthma is being thought to be caused by combination of genetic and environmental factors? Did you know that across this entire world the number of people

iodine (I2). As the iodine is added during the titration‚ the ascorbic acid is oxidized to dehydroascorbic acid‚ while the iodine is reduced to iodide ions as shown in the following equation: (studymode.js‚ 2010). Ascorbic acid + I2 (aq) -----------> 2I- (aq) + dehydroascorbic acid Due to this reaction‚ the iodine formed is immediately reduced to iodide as long as there is any ascorbic acid present. The amount of ascorbic acid is determined by the stoichiometry of the equations and the difference

ANAEROBIC DIGESTION ON BIODEGRADABLE WASTE FOR METHANE GAS CAPTURE BIODEGRADABLE WASTE: Biodegradable waste is a type of waste‚ typically originating from plant or animal sources‚ which can be decomposed by other living organisms. Biomass‚ manure‚ sewage‚ municipal waste‚ green waste and plant materials are some of these common biodegradable waste. ANAEROBIC DIGESTION: This is a series of biological processes in which microorganisms breakdown biodegradable materials in the absence of oxygen
