Question

a) what would happen if KOH solution is not hung in conical flask during experiment

b) seeds are not kept moist during experiment y?

Answer 1

(a) If KOH solution is not hung in conical flask during experiment, the CO₂ released during germination of seeds will not be absorbed due to which the level of water will not rise in the tube. In such a case, no conclusion could be drawn from the experiment.
(b) Seeds cannot germinate if not kept moist. Thus, no CO₂ will be formed.
