Non-electrolyte- a compound that will certainly dissettle in water to develop a solution that does NOT conduct electrical power due to ions not being produced. Examples- Sugar C12H22O11 and alcohol CH3OH.

You are watching: Which substance when dissolved in water forms a solution that conducts an electric current

Electrolyte- a compound that will disresolve in water to develop a solution that will certainly conduct electrical energy as a result of the presence of free ions.

Solubility Guidelines (ions that dissolve)


Ionization-an atom or molecules that acquires a charge by either getting or losing one or more electrons

Dissociation-When an ionic compound breaks up into its ions

Strong Electrolytes-Completely ionizes (or dissociates) when liquified in water. Classes of solid electrolytes include strong acids, solid bases and soluble salts. Some other ionic solids are CaCl2, NH4Cl, KBr, CuSO4, NaCH3COO (sodium acetate), CaCO3, NaHCO3 (baking soda).

Strong Acids HA(aq) → H+(aq) + A−(aq)

Back to Acid Base Links

Weak Electrolytes-an electrolyte that gives a low portion yield of ions as soon as liquified in water. For example, ammonia, NH4OH, carbonic acid, H2CO3, acetic acid, CH3COOH, and also many organic acids and bases are weak electrolytes.

Strength of Electrolytes and also Equilibrium Constants- Normally Speaking- Strong Electrolytes have actually incredibly big K worths. Weak electrolytes will have extremely small K values.
