Answer 1

Answer: She put salt in flask 1 and washing soda in flask 2 . She observed lots of bubbles in flask 2 but nothing in flask 1 . ... Lemon juice is acidic in nature and washing soda is slightly basic. Therefore, in the flask 2, reaction between the acid and the base takes place to release the carbon dioxide.
