Fill in the table

Reagents: Saliva, 6 ml 1% starch solution, 6 drops I, in KI, 6 ml benedict's reagent.
Materials: 12 Test tube (20 ml), 10 ml graduated cylinder, test tube rack, brush, 250
ml beaker, tripod, wire gauze, thermometer, alcohol lamp
Procedure:
1. Prepare 6 test tubes and place 1 ml saliva in each.
2. Add 1ml water to tube 1,2 ml to tube 2, 4 ml to tube 3,6 ml to tube 4, 8 ml to
tube 5 and 10 ml to tube 6. Mix thoroughly.
3. Transfer 1 ml of each into 6 separate test tubes (discard excess solution) and
add 1 ml of 1% starch paste. Mix well and heat in a water bath with
temperature maintained at 40°C for 30 minutes.
4. Divide each of the contents of each tube into 2 and test with:
Iodine Test – to half of the content of each tube, add 1 drop of iodine in KI
and note the color produced. Compare the intensity of color in each of the
6 tubes.
b. Benedict's – to 1 ml benedict's reagent, add 5 drops of the other half of
each tube and heat in a boiling water bath for 3 minutes. Note color of
precipitate.
-
5. Rank each tube according to decreasing reaction rate one (1) being the fastest
to hydrolyze and 6 being the slowest.
