← ScienceWhich outcome occurs in a solution when doping with magnesium chloride?
A)Increased electrical conductivity✓
B)Decreased solution viscosity
C)Reduced hydrogen bonding
D)Lowered surface tension
💡 Explanation
Increased conductivity appears because magnesium chloride introduces freely moving ions via ionic dissociation. This mechanism facilitates charge transport, therefore, electrical conductivity increases is most apparent, rather than viscosity changes or surface tension effects which are determined by molecular structure.
