Anyways, today we'll be learning about acids and bases!
Hey, where did Richie and Jack go? That was kind of weird (and lame).
This is a very basic unit, I expect everyone to do well. . . Yes, even you, Anne.
Acids, any molecules starting with H, ionizing into H+ ions in an aqueous solution will react with bases, any molecules ending with OH, ionizing into OH- in a solution. How they react is defined by how far apart they are on the pH scale, 0 being the strongest acids while 14 being the strongest bases, however there are exceptions that can reach negative or numbers past 14. We can tell how acidic or basic a substance is by using indicators, which can be either naturally or artificially derived, and they will give us a visual queue about the contents of what we're testing. Be careful since substances like phenolphthalein are slightly acidic, so only add a few drops at a time! To show how they react, we will be doing a titration lab later in the week and we'll see how acids and bases neutralize each other when they react. Extra credit will be given to whomever can pronounce phenolphthalein!
Wait, isn't second semester almost over?
What!? Hydrogen can react with hydrogen!? Sorry Mr. O'Sullivan, but I can't do this!
