‘ a student carried out the Benedictus test. Suggest a method, other than using a calorimeter, that this student could use to measure the quantity of reducing sugar in solution’ [2 marks ]
-
‘ an investigation, student wanted to underdog the solutions in 2 beakers , A and B. She knew one beaker contained maltose solution and other contained glucose- both same conc.
test 1- used Bénédicte solution test for reducing sugar
Test 2- added enzyme maltase heated and then used ebendicts soltuon for testng reducing sugars.
Results:
A: test 1- red, test2- red
B: test 1-red , test2- dark red
Explain the results for beakers A and B’
My answer for the first would be using different concentrations of the reducing sugar but only waffling coz I’m guessing that’ll be one mark 😂
I’m clueless for the second question
Very confused ahaha
