Question

10 ml of Acetic Acid was taken in each of 2 test tube blue and red litmus paper when dipped in test tube one by one and A Pinch of a solid sodium bicarbonate was added to test tube second write observation with Prince conclusion in both the test tube

Answer 1

(i) When a blue litmus paper comes in contact with the acetic acid solution, it will turn to red. This is because the acetic acid is acidic in nature, and the litmus paper turns red to indicate its acidic nature.

(ii) When Sodium bicarbonate (NaHCO₃) is added to the test tube containing acetic acid, a reaction will occur which results in the evolution of gas in the form of bubbles. This released gas in Carbon dioxide which can be confirmed by passing it through limewater, which turns milky after CO₂ is passed through it.
The presence of CO₂ is known to bring down the pH levels. So, the acidic nature will probably increase and the blue litmus paper will turn red.

Answer 2

Answer:

1) when blue litmus paper is added in test tube one the colour of litmus paper turns into red as acetic solution is acidic in nature so it turns the colour of litmus paper into red

2)when sodium bicarbonate or hydrogencarbonate is added in test tube two CO2 will release as we know when an acid like acetic acid in this case reacts with nahco3 a salt nacl,CO2 and h2o will release.the gas CO2 that is released turns lime water milky
