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...

When forms. the following molecular compounds dissolve in water, they disperse in different In HNOs solution, only H' and NO; are found, no HNOs molecules. In CHsCOOH solution, much greater amount of CH,COOH molecules and some H and CH3COO ions are found. In C3H/OH solution, only C3H OH are found. Classify and explain which compounds are electrolytes, nonelectrolytes, strong electrolytes, weak electrolytes? (8 pts) Electrolyte: Nonelectrolyte: Weak electrolyte: Strong electrolyte:

Question 8 (1 point) For this reaction, consider the auto-ionization reaction of water (shown below) - this reaction is endothermic (AHRXN>0). Based on this information, identify how would the pH of pure H20 change due to a decrease in temperature (T)? H2O(1) + H20(1) OH"(aq) + H30(ag) the pH of pure H20 would not change just by decreasing temperature the pH of pure H20 would increase with a decrease in T the pH of pure H20 would decrease with a...
