1. ELECTROLYTES
Substances that when dissolved in water will conduct electricity
Ions must be in the solution for a current to be able to flow.
The more ions present, the stronger the electrolyte

2. ELECTROLYTIC SOLUTIONS
- substance that conducts an electric current when dissolved in water
Electrolytic
Electrolyte
Only acids, bases and salts
are electrolytes
acids
bases
salts

3. NON - ELECTROLYTIC SOLUTIONS
- substance that does not conduct an electric current when dissolved in water
Alcohols
100% pure water
2 non-metal
Compounds (covalently bonded)

4. Important Facts Facts All acids, bases and salts are electrolytes
The fewer the ions present in a compound the weaker the electrolyte
The stronger the acid or base the better the electrolyte

5. EXAMPLE #1 Which of the following are electrolytes? 1. NO2 2. CH3OH
3. KOH
4. H2CO3
5. C2H6
6. CF4
7. CO2
8. HF

6. EXAMPLE #2 Which of the following are not electrolytes? 1. CO2 2. SF6
3. NaOH
4. NH4OH
5. C3H8
6. C2H5(OH)
7. H20 (distilled)

7. KEY POINTS
Electrolytic solutions- conduct electricity (acids, bases and salts)
Non-electrolytic solutions – do not conduct electricity (100% pure distilled water, pure alcohols, 2 non-metal compounds)
