Reactions in Solution: The Idea
of an Electrolyte
Electrolytes
- An electrolyte is something which, when dissolved in
water, causes the resulting solution to conduct
electricity. Since the carriers of electricity in
solution are ions, then an electrolyte must produce some
ions in water.
- Water itself is so weakly ionized that almost no
current can flow through it. It is generally considered a
nonelectrolyte. Sugar (sucrose) being a molecular
compound does not ionize in water and is also a
nonelectrolyte.
- NaCl, BaCl2, NaOH,
AlCl3...almost any combination of metal and
non metal forming an ionic compound will ionize
completely on entering solution in water and is a
strong electrolyte.
- Strong acids and strong bases are always strong
electrolytes.
