Question

Does Cellulose or cotton react with base?

please give correct answer i will mark brainliest!

Answer 1

Answer:

Explanation:Cotton cellulose was acid treated either in water or in ethanol, containing 1.39% HCl, at 45 and 65 °C for 1–5 h. The morphology and molecular weight distribution of celluloses before and after acid treatments were observed, and the differences in the structure of celluloses treated at different conditions were compared. The soluble sugar contents of celluloses during acid treatment were lower than 6%. Native cellulose showed smooth surface, whereas tiny pin-holes (15–20 nm in diameter) and wrinkles were found on the surface of acid-treated cellulose. Cellulose tended to have pin-holes after treated in ethanol at 65 °C.
