Electrolytes

Electrolytes are substances that, when dissolved in water, conduct electricity. Non-electrolytes are substances that don't conduct electricity when dissolved in water.

Strong and Weak Electrolytes

There are 2 kinds of electrolytes, strong and weak. Strong electrolytes exist in solutions and tend to completely dissociate and break down into ions. The following are strong electrolytes -

• All strong soluble salts (shown above)
• All strong acids (HCl, HBr, HI, HNO₃, H2SO₄,HClO₄)
• All strong bases (NaOH, LiOH, KOH, ~Ba(OH)₂)

Weak electrolytes on the other hand are solutes that exist in solutions mostly in the form of molecules (they don't completely dissociate into ions).

• All weak acids (HF, HC2H3O2, see table)
• All weak bases (NH3, see table)
