Using Raoult's law explain how the total vapour pressure over the solution is related to mole fraction of components in the following solutions. (ii) NaCl(s) and H_(2)O(l) |
| Answer» Solution :(ii) As solute NaCl is non-volatile, vapour pressure of SOLVENT in solution is equal to vapour pressure of solution, i.e., `P_("total") or P_("SOLN")=p_(H_(2)O)=x_(H_(2)O)xxp_(H_(2)O)^(@)` | |
