For all solutions of electrolytes, write the equation that describes the dissolution process.
I have these two so far. are they correct? what else is left?
NaCl -------> Na+ + Cl-
NaHCO3 + H2O ----> H2CO3 + NaOH

What would be the purpose of this lab based on the following information? Colligative Properties II Colligative Property is a property of a solution that depends only on the number of solute molecule present. Osmotic pressure, freezing point depression, boiling point elevation, and vapor pressure lowering are all colligative properties. In today’s lab we will look at three of these properties. Electrolytes are substances that forms ions in solution that conduct electricity. Electrolytes can either be an acid, base or...
