By raising the temperature 1°C, conductance increases by 2 to 2.5%. Which is due to reduced _ of ions?
Correct answer: A. Hydration
- A. Hydration
- B. Neutralization
- C. Hydrolysis
- D. Ionization
Explanation
Hydration is inversely propotional to conductance. In hydration, ions are surrounded by water molecules so their conductance decreases. So, in order to increase conductance, hydration must decrease to allow electron flow (to conduct electricity).

About Chemical Bonding
Chemical bonding explains molecular shape through VSEPR theory and distinguishes sigma bonds from pi bonds. Questions involve hybridization, bond angles, dipole moment and bond energy, including how electron-pair repulsion determines geometry and how bond polarity differs from the overall polarity of a molecule.
