Which risk increases when solid sodium chloride experiences elevated humidity?

A)Increased ionic conductivity
B)Decreased lattice energy
C)Reduced electrostatic attraction
D)Enhanced covalent character

💡 Explanation

Increased humidity introduces surface water, promoting hydration of ions and facilitating ion mobility via Grotthuss mechanism; because ion migration leads to higher conductivity it does not represent the solid state. Therefore, ionic conductivity increases, rather than the opposite because water solvates ions preventing lattice association.
