Why sealed soda water bottle on opening shows the evofution of gas with efferescence ?

(i) Gas A is more soluble in water than Gas (B) at the same temperature. Which one of the two gases will have the higher value of K_(H) (Henry's constant) and why? (ii) In non-ideal solution, what type of deviation shows the formation of maximum boiling azeotropes ?

Why are aerated water bottles kept under water during summer ?

A chemist opened a cupboard to find four bottles containing water solutions, each of which has lost its label. Bottles 1,2,3 contained colourless solutions, Whilst bottle 4 contained a blue solution. The labels from the bottles were lying scattered ont he floor of the cupboard. They were copper (II) sulphate sodium carbonate lead nitrate hydrochloric acid By mixing sammples of teh contents of the bottles, in pairs, the chemist made the following observations: (i) Bottle 1 + Bottle 2 white precipitate (ii) Bottle 1 + bottle 3 white precipitate (iii) Bottle 1 + Bottle 4 white precipitate (iv) Bottle 2 +Bottle 3 colourless gas evolved (v) Bottle 2+ Bottle 4 no visible reaction (vi) bottle 3 +bottle 4 blue precipitate Q. Nature of gas evolved in observation (iv) is:

A cylindrical vessel of height 500mm has an orifice (small hole) at its bottom. The orifice is initially closed and water is filled in it up to height H. Now the top is completely sealed with a cap and the orifice at the bottom is opened. Some water comes out from the orifice and the water level in the vessel becomes steady with height of water column being 200mm. Find the fall in height(in mm) of water level due to opening of the orifice. [Take atmospheric pressure =1.0xx10^5N//m^2 , density of water=1000kg//m^3 and g=10m//s^2 . Neglect any effect of surface tension.]

Explain why : Effervescence is seen on opening a bottle of soda water.

If water in a closed bottle is taken up to the moon and open, the water gets

What do you observe when : Opening the soda water bottle.
