For a binary ideal liquid solution, the total vapour pressure of the solution is given as:

When non-volatile solute is added to a pure solvent, the 

A mixture of $$KCl$$ and $$KClO_3$$ weighing $$1.8$$ gms was heated . After the reaction, the dry oxygen gas generated occupied $$140$$  ml at STP. What percent of original mixture was $$KClO_3$$?

The reduction potential of hydrogen electrode will be positive if 

For an ideal solution with $$P_A$$ > $$P_B$$ , which of the following is true?

18 g of glucose $${ (C }_{ 6 }{ H }_{ 12 }{ O }_{ 6 })$$ is added to 178.2 g of water. The vapour pressure of water for this aqueous solution at $${ 100 }^{ \circ  }C$$ is ?

Calculate solubility (in moles / litre) of a saturated aqueous solution of $$Ag_3PO_4$$ if the vapour pressure of the solution becomes 750 torr at 373 K
(Assume molality=molarity).

The solubility of a specific non-volatile salt is $$4g$$ in $$100g$$ of water at $$25^{\circ} C$$. If $$2.0g,4.0g$$ and $$6.0g$$ of the salt added of $$100g$$ of water at $$25^\circ C$$, in system X, Y and Z. The vapour pressure would be in the order:

Liquids $$A$$ and $$B$$ form an ideal solution. At $$30^o$$ C, the total vapour pressure of a solution containing $$1$$ mol of $$A$$ and $$2$$ mols of $$B$$ is $$250$$ mm $$Hg$$. The total vapour pressure becomes $$300$$ mm $$Hg$$ when $$1$$ more mol of A is added to the first solution. The vapour pressures of pure $$A$$ and $$B$$ at the same temperature are 

Consider a binary mixture of volatile liquids. If at $$X_A=0.4$$ the vapour pressure of solution is $$580\ torr$$ then the mixture could be $$(p_{A}^{0}=300\ torr, p_{B}^{0}=800\ torr)$$
