The value of Henry's constant KH is :
Assertion (A) : Henry's law constant (K_H) decreases with increase in temperature. Reason (R) : As the temperature increases, solubility of gases in liquids decreases.
At the same temperature, CO₂ gas is more soluble in water than O₂ gas. Which one of them will have higher value of KH and why?
How does the size of blood cells change when placed in an aqueous solution containing more than 0·9% (mass/volume) sodium chloride?
1 molal aqueous solution of an electrolyte A₂B₃ is 60% ionized. Calculate the boiling point of the solution. (Given : Kb for H₂O = 0·52 K kg mol⁻¹)
The vapour pressures of A and B at 25ºC are 75 mm Hg and 25 mm Hg, respectively. If A and B are mixed such that the mole fraction of A in the mixture is 0·4, then calculate the mole fraction of B in vapour phase.
