Answer:- Mass of a gas dissolved per unit volume of a solvent is directly proportional to the pressure of the gas in equilibrium with the solution at a given temperature  I.e C=KP. Where,   P=partial pressure of the gaseous solute above the solution, C=concentration of dissolved solute & K=Henry's law constant.

Answer:- It states that if a system in equilibrium is subjected to a stress (i.e change of temperature, pressure or concentration), the equilibrium shifts in such a way so as to undo the effect of the stress imposed.

Answer:- A solution which maintains its hydrogen (or hydroxyl) ion concentration at an approximately constant level,which does not change by adding water or small amounts of any acid or base to it is called a buffer solution.
