Test 1 Flashcards
What happens when equilibrium is reached?
There is no further change in the concentration of the molecules/substances
What is disassociation?
When two separate ions break apart
NaCl ↔️ Na+ + Cl-
What is an acid
A substance with the ability to donate hydrogen ions
Proton donor
What is a base
A substance that is able to accept a hydrogen ion
If the hydrogen ion concentration increases, then pH __________
Decreases
PH formula
pH = -log[H+]
What factor affects the dissociation of molecules in solution?
Temperature
What does a decrease in temperature do?
Decreases energy
Decreases dissociation
Decreases concentration of all ionized components
Increases pH
Equilibrium of dissociation is moved to the left
Why is water a weak acid
It has the ability to donate a hydrogen ion
What is the pH of neutrality at 21C
7.0
What influences partial pressure
The number of molecules in the gas phase
At equilibrium the partial pressure in the gas phase will ________ the partial pressure of the gas in the solution
Equal
What is Henry’s law
Dissolved = solubility * partial pressure
ml gas/100 ml solution) = (ml gas/100 ml sol/ mmHg) * (mmHg
What is the solubility of O2 at 37 degrees
0.003 ml O2/100 ml blood/mmHg
What is the solubility of CO2 at 37 C
0.06 ml CO2/100 ml blood/mmHg
