Khan Academy: Hypotonic, Isotonic, and Hypertonic Solutions (Tonicity)

After removing the shell from a raw egg, cell biologists soak the egg in either a hypotonic, hypertonic, or isotonic corn syrup solution. They calculate the percent change in mass and compare it to the strength of the solution in a...

Hypotonic, isotonic and hypertonic solutions (tonicity). Seeing the effect of various types of solution on the direction of osmosis. [6:29]

A video lecture discussing the properties of homogeneous mixtures and how to distinguish between the different types. Understand that homogeneous mixtures that have large particles that eventually settle to the bottom are known as a...

See some examples of calculating pH of 0.25 M solution of sodium acetate, and calculating the pH of 0.050 M solution of ammonium chloride. [14:15]

Find out how tonicity is determined by ions that don't move across membranes and how it affects the movement of water. Rishi is a pediatric infectious disease physician and works at Khan Academy. [11:02]

See an example of calculating the pH of solution that is 1.00 M acetic acid and 1.00 M sodium acetate using ICE table. Also shown is another example of calculating pH of a solution that is 0.15 M ammonia and 0.35 M ammonium nitrate. [13:19]

See how each of these terms tells us something different about a solution. [4:04]

A quick overview of Ka and pKa. See an example of calculating the pH of a weak acid solution. [9:31]

See how each of these terms tells us something different about a solution.

Learn the definitions of a solution, solute, and solvent. Understand how molarity is used to quantify the concentration of solute, and comcalculations related to molarity.
