fermentation 3 ml of 1.5M NaOH

Which of the following results would you expect?

Question 2A A brick red precipitate indicating the

presence of a reducing sugar.B A white precipitate indicating the

presence of CO2 gas.C A dark red colour indicating starch.D No precipitate because the reducing

sugar will have totally fermented.E A yellow precipitate indicating ethanol.
