when baking soda is mixed with lemon juice Bubbles are formed with evolution of a gas what type of change is this explain
Answers
Ans. When baking soda is mixed with lemon juice, the bubbles which are formed with the evolution of a gas is due to the evolution of carbon dioxide gas. Since, there is formation of a new substance in this reaction, it is a chemical change.
Answer:
when baking soda is mixed with lemon juice bubbles are formed with the evolution of Carbon dioxide.
Explanation:
Baking soda and citric acid react chemically to generate sodium ions, citric acid ions, carbon dioxide ( co2), and water when they come into contact with one another. In our air, carbon dioxide gas is a common element. It is a gas that we naturally exhale and also contributes to the bubbles in carbonated beverages.
Sodium bicarbonate and citric acid in Bath Fizzies react with water to produce carbon dioxide bubbles. Baking soda, commonly known as sodium bicarbonate, is a weak base in this acid-base reaction, whereas citric acid is just a weak acid.
therefore the bubbles are formed due to the formation and evolution of carbon dioxide gas.
