Add 10 mL of the 30% sucrose solution to 10 mL of 15 mg/mL invertase into a beaker and quickly add the mixed solution into an empty Polarimeter sample cell. Accurately measure and record the height of the liquid in the cell to the nearest 0.1 cm. Caution: Treat all laboratory chemicals with caution. Prudent laboratory practices should be observed.

Clearly, all of the sucrose that there will be in the new solution must come from the 10 mL of the 50% (w/v) sucrose solution that you add to the 40 mL of water. (The 40 mL of water, itself, contains no sucrose.) Therefore, the total mass of sucrose in the new solution must be 10 mL X 0.5 g/mL = 5 g. Note that in the original sucrose solution ...

An aqueous solution of sucrose, common table sugar, is converted to ethanol and carbon dioxide by the action of enzymes in ordinary baker’s yeast. Most of the reactions of fermentation can be found on pp. 1106-7 in your McMurry lecture text (glycolysis pathway.) The missing reactions are those that convert sucrose to glucose and pyruvate to ...

Measure 5 ml of starch solution using the 10 ml graduated cylinder and pour it into the tube. Thoroughly rinse the graduated cylinder, shake dry, and measure 5 ml of glucose solution. Pour this into the tubing as well. Tie the second end of the tubing in an overhand knot and rinse it under the faucet. Set your “cell” on a clean surface.

Sucrose solution: Add 5 grams of sugar to 100ml of water. Stir until the sugar has dissolved. Denatured enzyme solution. Place twenty milliliters of enzyme solution into a Pyrex test tube. Add two hundred ml of water to 400ml Pyrex beaker. Place the test tube in the beaker. Gently lay the test tube so it rests on the side of the beaker.
