Repeat the procedure in Exercise 55, but for the titration of 25.0 mL of 0.100 M propanoic acid (HC3H5O2, Ka 1.3 105 ) with 0.100 M NaOH.

Colligative properties only on the number of solute particles in the solution and not the identity of those particles. 2. a. freezing point- the point at which a liquid becomes a solid 1 2 b. molality- moles of solute per kilogram of solvent 3 c. hydrophilic-materials with a special affinity for water — those it spreads across, maximizing contact d. hydrophobic- that naturally repel water, causing droplets to form 3 3. Most of these substances cause skin and eye irritants, as well as dangers from ingestion. 4.
