(a) Differentiate between a saturated and an unsaturated solution .How will you test whether a given solution is saturated or not ? (b) How would you prepare a saturated solution chloride in water at 25^(@)C ? What will happen if this solution is cooled to 10^(@)C ?

In a experiment to measure the pH values of solutions, a student placed strips of universal indicator paper in foru beakes containig solutions A,B, C and D. The colour of universal indicator paper in these solutions is a shown below: The solution having lowes pH value is:

10^(-5)M HCI solution at 25^(@)C is dilluted 1000 times. The pH of the diluted solution will

30xx10^(-4) kg of urea dissolved in water to make 500 mL aqueous solution and this solution is isotonic with cane - sugar solutions .How much mass of cane sugar in its one litre solutions ? (H=1,N=14,O=16,C=12)

10 g of oxalate was dissolved in 300 mL of solution. This solution required 250 mL of (M/10)KMnO_(4) in acidic medium for complete oxidation. The percentage purity of oxalate ion in the salt is :

Four containers are taken at the same temperature , as shown in the figure : (A) 500 mL of 10% (w/w) urea solution (B) 500 mL of 10% (w/w) urea solution (C) 400 mL of 10% (w/w) urea solution (D) 500 mL of 20% (w/w) urea solution The correct order of vapour pressure of these solution is :
