← ScienceWhich outcome occurs when a firefighter sprays water on sodium chloride?
A)Decreased oxygen dissociation from hemoglobin
B)Ionic conductivity in the solution increases✓
C)Flash point of flammable liquids decreases
D)Oxidation rate of nearby metals lowers
💡 Explanation
Ionic compounds dissociate in water to form ions. Because sodium chloride dissociates releasing mobile Na+ and Cl- ions in solution, electrical conductivity increases; therefore ionic conductivity is directly enhanced rather than decreasing oxygen levels or changing flash points.
