Presentation transcript:

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

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

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

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 Important Facts

Which of the following are electrolytes? 1.NO 2 2.CH 3 OH 3.KOH 4.H 2 CO 3 5.C 2 H 6 6.CF 4 7.CO 2 8.HF

Which of the following are not electrolytes? 1.CO 2 2.SF 6 3.NaOH 4.NH 4 OH 5.C 3 H 8 6.C 2 H 5 (OH) 7.H 2 0 (distilled)

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