Why are acids and bases good conductors of electricity in solution?

To conduct electricity, compounds need to have charged particles and be able to move. Acids and bases can do both of those things:

Charged Particles
Acids and bases can dissolve to form ions which are charged particles. NaCl forms Na+ and Cl- ion, hence it can conduct. However, say you take sugar in water, it doesn't conduct because it doesn't form ions.

Movement
As the acid/base is in a liquid medium (the solution), they can move.

Hope that helped and feel free to ask more questions!

Adozen is 12, and your needing to calculate the weight of one medium egg, so i would do 21/12=1.75 per egg, and check your answer by doing 1.75 * 12= 21 : ) : ): ): ): ) i hoped i
