Give reasons for Elevation of boiling point of 1 M KCl solution is nearly double than that of 1 M sugar solution. |
| Answer» Solution : KCl is ionised into `K^+` and `Cl^-`ions. Thus a 1 M KCl solution will contain 1 MOLE of `K^+` ions and 1 mole of `Cl^-` ions. The solution will contain 2 moles of particles (ions). On the other hand, 1 M sucrose solution will contain 1 mole of particles as it does not ionise. Therefore elevation of boiling POINT of 1 M KCl solution is nearly DOUBLE than that of 1 M SUGAR solution. | |
