Scribe Post.

Okay, today we went over the work sheet called Ionization Equations and Constants, that was given to us on Monday, the answers are as follows:

1.If they have more than one Hydrogen, there will be more ionization equations.
2.The Ka decreased as you go down the list
3.HCO3- is weaker because its Ka is smaller than H2PO4-.
4. phosphorous <-> H+ + H2PO3-, phosphorous - 1H <-> H + HPO3, phosphorous - 2H <-> H + PO3.
5.
a) Ka=[H][HCl]/[H2CO3]
b) Ka=[H+][HCOO-]/[HCOOH]
6. because it's a 1 to 1 ratio.

also we are to do questions 6 to 15 by tomorrow.
next scribe is "romina".
