Solution ABenedict’s trial:
Blue colour turned to brick ruddy precipitate. Reducing sugar is present in the solution A. Iodine trial:
The colour remained unchanged. Starch is absent in solution A. Solution B Benedict’s trial:
The bluish colour remained unchanged. Reducing sugar is absent in solution B. Iodine trial:
The colour bend into dark bluish colour. Starch is present in solution B.

( from tubes 1 – 4 into 1â€² – 4â€² )
110 ml solution B
1 milliliter saliva 37Blue colour turned into semitransparent green. Blue colour turned to green and eventually moderate sum of brick ruddy precipitate suspended in solution. The solution was opaque. 210 ml solution B
3 M HCI 37The blue coloured solution remains unchanged. The blue coloured solution remains unchanged. 310 ml solution B
3 M HCI 95White coloured semitransparent suspension formed in moderate sum. A really large sum of white suspension formed which is really opaque. Turned back into translucent and staying solution was bluish which
is semitransparent. 410 ml solution B
1 milliliter saliva 95The blue coloured solution remains unchanged. The blue coloured solution remains unchanged every bit good.
In the experiment. the enzyme amylase was involved. Amylase interrupting down the amylum suspension into maltose and maltose into glucose when HCL was added into solution B. This is because solution B was hydrolyzed and the H+ ions present break down the bond in between molecules of the solution B. Saliva enzyme works the best at the optimum…
