Syringe Test Experiment

Syringe test Experimental expression words: - Calcium carbonate + Hydrochloric acid = Calcium chloride + Water + Carbon dioxide symbol: - CaCO ^. 2 HC = CaCl + H 0 + CO equipment: - Flask, glass gas injector, plug, marble chip CaCO? ·)) And the pipeline. Eyes should be visible when measuring chemicals and experiments due to harmful chemicals to be handled while wearing goggles during safety testing.

Apparatus: The equipment I use for experiments is test tube, gelatin coated film, splint, syringe, stopwatch, thermometer, electric water bath. This device is suitable for this experiment. Easy to use, easy to set up and use, and easy to collect results. I first measure the amount of protease solution using a syringe, the syringe is 10 cm 3, and then put it in a test tube. Then I attached each of the two developed films and hooks to each so that they can be easily removed from the tube. Tags are attached to the wires to make it easier to see which movies are which movies. Next, the test tube is placed in an electric water bath at a specific temperature, for example 30 ° C. I kept it in the bathtub for 3 minutes and then put two films in a test tube. Every 30 seconds, check if the film is transparent. When the two films became transparent, I took them out of the test tube.

First we weighed 12 ml of starch in a syringe and put it in a test tube. Next we weighed 1 ml of amylase and put it in a second tube. Place these tubes in tubular black. The two liquids were then heated under a Bunsen burner in a water bath. When the two substances reach a certain temperature, we add them together in separate tubes. After that, I used 1 drop of amylase / starch every 30 seconds and pipetted into a white tile. After that, I put a drop of iodine in the white tile to show the color change of amylase / starch. Continue this until amylase / starch turns to pure yellow.

Method / Material I used 50 grams of the same kind of apple for my test. Pectinase and cellulase were used according to tests using laboratory materials such as beakers, syringes, cylinders. For example, in one of my tests, I weighed an apple. Then I added pectinase and / or cellulase with a syringe. Then I incubated the mixture and recorded the amount of juice produced after a certain period of time. My test found that addition of pectinase and cellulase under certain conditions increased apples juice.
