you have provided a spoonful of baking soda and a beaker containing lemon juice what happens when you add baking soda to lemon juice it is physical or chemical changes ?
Answers
Explanation:
When baking soda is mixed with lemon juice, the bubbles which are formed with the evolution of a gas are due to evolution of CO2 gas. Since there is formation of a new substance in this reaction, it is a chemical change. Acid react with carbonates to give salt and releasing carbon dioxide and water.
Answer:
When baking soda (Sodium hydrogen carbonate) is mixed with lemon juice (citric acid), bubbles are formed. The bubbles are formed due to the evolution of carbon dioxide gas. This is a chemical change.
In this change, citric acid contained in lemon juice reacts with sodium hydrogen carbonate which results in the evolution of carbon dioxide gas.
Lemon juice + Baking soda → Carbon dioxide + Other substances
Citric acid Sodium
Hydrogen carbonate
