Q. Define-
i) Molal elevation constant.
ii) Molal Depression constant.
what are the applications of Henry's law?
which is more concentrated 1 molar or 1 molal?
What is a decimolar solution?
A decimolar solution of potassium ferricyanide (K4[Fe(CN)6]) is 50% dissociated at 300k. calculate the osmotic pressure of solution.
Resistance of a conductivity cell filled with 0.1 M is 100 ohm. If the resistance of the same cell when filled with 0.02 M KCl solution is 520 ohms, calculate the conductivity and molar conductivity of the 0.02 M KCl solution. Conductivity of 0.1 M KCl solution is 1.29*10-2 S cm-1.
what are the differences btw ideal and non ideal solns?
the concentration of NO3 ions when equal volumes of 0.1 M AgNO3 and 0.1 M Nacl are mixed together is ?
what is the mole fraction of the solute in 2.5 m aqueous solution ??
vapour pressure of chloroform and dichloromethane at 298 k are 200mm of hg and 415mm of hg respectively.
1)calculate the vapour pressure of solution prepared by mixing 25.5 g of chloroform and 40g of dichloromethane at 298K.
2)mole fraction of each component in vapour phase.
why aquatic species are more comfortable in cold water than warm water?
If N2 gas is bubbled through water at 293 K, how many millimoles of N2 gas would dissolve in 1 litre of water. Assume that N2 exerts a partial pressure of 0.987 bar. Given that Henrys law constant for N2 at 293 K is 76.48 kbar.
1. NaCl or CaCl2 is used to clear snow from roads. why
2. what is an antifreeze?
3. what is de icing agent?
4. what is vant hoff factor for a factor which undergoes tetramerisation in an organic compound.
