Tues-Day 2
We described what occurs when an egg is fertilized by a sperm cell in the oviduct as well as what occurs when an egg is not fertilized (menstruation).
We briefly talked about embryonic development with respect to the placenta and umbilical cord as well as the gestation period.
AP Chem - we discussed the real reason that a given salt yields a neutral, acidic, or basic solution by noting whether a given anion or cation is "strong" enough (typically, having a high enough CHARGE DENSITY) to hydrolyze water and generate either hydronium or hydroxide.
We then did a few pH, pKa, pKb ICE table problems to determine the pH of a given molar salt solution.
