Yes, the conductivity of NaOH is different from NH3. NaOH is a strong base, while NH3 is a weak base. This means that NaOH dissociates completely in water, while NH3 only partially dissociates. As a result, NaOH has a higher concentration of ions in solution than NH3, which makes it a better conductor of electricity.

The conductivity of a solution is determined by the concentration of ions in the solution. The more ions there are in solution, the higher the conductivity. NaOH dissociates into Na+ and OH- ions, while NH3 dissociates into NH4+ and OH- ions. The Na+ and OH- ions are both more mobile than the NH4+ ion, so NaOH has a higher conductivity than NH3.

In addition, the temperature of the solution also affects the conductivity. The higher the temperature, the more ions are in solution, which increases the conductivity.
