An electrolyte XY_(2) is 40% ionized calculate van't Hoff factor.

What are the conditions under which a rocket, fired from the earth, launches an artificial satellite of the earth?

Why do we get abnormal molecular masses of the substances using colligative properties of solutions only sometimes ? What are the natures of these abnormalities?

Why is the mass determined by measuring a colligative property in case of some solutes abnormal? Discuss it with the help of van't Hoff factor.

What is the Van't Hoff factor for sodium phosphate ?

Compreshension -I The experimental values of colligative properties of many solutes in solution resembles calculated value of colligative properties. However in same cases, the experimental value of colligative property differ widely than those obtained by calculation. Such experimental values of colligative properties are known as Abnormal values of colligative properties are : (i) Dissociation of solute : It increases the colligative properties. (ii) Association of solute : It decreases the colligative properties e.g. : Dimerisation of acetic acid in benzene If degree of dissociation of an electrolyte A_(2)B_(3) is 25% in a solvent, then

What is responsible for the flow of current through (i) a metallic conductor, (ii) an electrolyte?
