Determining van't hoff factor
WebThe van't Hoff factor is the number of particles that a single solute will dissociate into when added to a solution. MgCl 2 will dissociate into three particles: 1 Mg 2+ cation and 2 Cl - anions. Since 2m of MgCl 2 has the highest molality as well as the largest van't Hoff factor out of the options, it will result in the highest boiling point. WebDissociation factor which is also known as Van''t Hoff factor plays an important role where electrolytes are involved. For instance, it can be used in adjust...
