To test for non-reducing sugars, a second Benedict’s test must be done. Which sequence of steps gives the correct procedure for testing for non-reducing sugar before performing the second Benedict’s test?
- APerform the Benedict’s test, which gives a negative result. Warm gently with dilute hydrochloric acid. Neutralise with sodium hydrogencarbonate.
- BPerform the Benedict’s test, with the colour of the solution remaining red. Boil with dilute hydrochloric acid. Neutralise with sodium hydrogencarbonate.
- CPerform the Benedict’s test, with the colour of the solution remaining blue. Boil with dilute hydrochloric acid. Neutralise with sodium hydrogencarbonate.
- DPerform the Benedict’s test, which gives a negative result. Neutralise with sodium hydrogencarbonate. Warm gently with dilute hydrochloric acid.
