Which effect occurs when NaCl dissolves into polar solvent?

A)Increased electrical conductivity of solution
B)Decreased solution surface tension results
C)Reduced solvent's boiling point occurs
D)Solution's pH value becomes elevated

💡 Explanation

Increased conductivity occurs because sodium chloride dissociates via ionization, forming mobile Na+ and Cl- ions; therefore, they enable charge transport and raise the solution's conductivity, rather than affecting properties like surface tension directly.
