Method

heat

We put into Fehling's solution.

The deeper the red is, the more sugar there is.

Condition of experiment.1. We checked whether active carbon

speeds up decomposition.

2. We checked whether changing 　　　　　　　　　　　　　　　　　　　　　　　　　あ concentration of the sulfuric 　　 acid speeds up decomposition.

result《 No active carbon 》０ 0.1 0.5 1 2

2mol/L is the reddest ＝ Decomposition is progressing

Sulfuric acid concentration （ mol/L ）

Best reaction

3 6 9 12《 About carbonization 》

The solution of more than 6mol/L is black.　　　　　⇒ Ingredient is carbonized.

《 Active carbon 》０ 0.1 0.5 1 2 3 6 9 12

12mol/L is the reddest. ＝ Decomposition is progressing.

Best

reaction

：sugar or sulfuric acid There are small holes in activated carbon.
