Cheese final

Question 1

Osmotic Pressure equation

Answer 1

pi = iMRT
where
M: mol/L
R: 0.08206 Latm/molk
T: in K

Question 2

1 atm= ___torr

Answer 2

1 atm= 760 torr

Question 3

Henderson-Hasselbalch Eqaution

Answer 3

pH = pKa + log (base/acid)

Question 4

What are examples of Oxyacid acids and how do you determine their strength

Answer 4

NO3- nitrATE -> HNO3 Nitric acid
CO3^2- carbonATE -> H2CO3 carbonIC acid
SO4^2- sulfATE -> H2SO4 sulfurIC acid
PO4^3- PhosphATE -> H3PO4 PhosphorIC acid
ClO3^- CholrATE -> HClO3 ChlorIC acid
C2H3O2^- acetATE -> HC2H3O2 AcetIC acid

For oxyacids, for a given central atom, the acidity increase with an increasing number of oxygen atoms
