did mixing solution of conjugates pH HH calcs and started SRFCs
must elaborate on why buffers work vs. plain acid or base solution neutralizations...draw picture...
in HCl or NaOH solutions, the only thing to react with the added base or acid is H or OH directly which is why the pH changes so much!
Honors- did a really good 8-part question starting with Mg + HCl balancing to gas collection over water to Dalton's Law to stoichiometry to mol fraction to molarity problem...juuust started Graham's ...finish that tomorrow and it's on to calorimetry...test next Tues...put up objectives....
