When the bottle of soft drink is opened, what would take place from the following? (A) Solubility of dissolved gas decreases. (B) bottle released internal pressure. (C) effervences evolved from the bottle. (D) increase in external pressure. Identify the correct choice.

Options

  1. A(A), (B) and (C) only.
  2. B(A), (B) and (D) only.
  3. C(A), (B), (C) and (D).
  4. D(B), (C) and (D) only.

Correct answer

A. (A), (B) and (C) only.

Step-by-step solution

Soft drinks are bottled under high pressure to increase the solubility of CO₂ gas in the liquid, according to Henry's law. When the bottle is opened, the high internal pressure is released to match the atmospheric pressure. Thus, statement (B) is correct. As the pressure decreases, the solubility of the dissolved gas decreases. Thus, statement (A) is correct. The excess dissolved gas escapes rapidly in the form of bubbles, causing effervescence. Thus, statement (C) is correct. The external atmospheric pressure rema
