Discussion of water as a solvent. Includes material on hydrogen bonds, hydration, hydrophobic effect, acids, basses, and pH.

Students will use citric acid and sodium carbonate solutions to see that adding a base to an acidic solution makes the solution less acidic. Students will then use a base to help them identify which of two acidic solutions is more...

Students see a demonstration of a color change using universal pH indicator and then change the concentrations of an acid and a base using a universal indicator to test the pH of the resulting solutions. Through an animation, they see...
