Water, Weak Acids & Bases Flashcards
Name the 3 strongest bonds in order
- Ionic (e transfer)
- Covalent (e sharing)
- metallic (glue)
What 3 elements can form a H bond?
N,O,F
List these bonds in order of strength (Ion Dipole, Dipole dipole, H bond & Dipole induced dipole)
- Ion dipole
- H bond
- Dipole dipole
- Dipole induced dipole
How many water molocules does a h2o molocule bind to in liquid sate? Solid sate?
Liquid: 3.4
Solid: 4
What does AMPHIPATHIC mean?
AKA: Amphiphillic having both hydrophobic and hydrophilic parts
Label each symbol in the equation:
∆G = ∆H - T∆S
∆G = Gibbs free energy ∆S = Entropy ∆H = Enthalpy T = Temperature
What are the 4 coliigative properties?
- vapor pressure
- boiling point
- melting point
- osmotic pressure
What happens to a cell in a Hypotonic/Hypertonic solution?
Hypotonic: Water rushes into cell, cell swells
Hypertonic: Water leaves cell, cell shrinks
Define an acid and a base
Acid: H+ DONORS
Base: H+ ACCEPTOR
What is pKa?
pKa is the pH in which the acid and the Base are in the same concentration.
Is the solution a stronger acid or base when it has a larger Kz and smaller pKa?
Stronger ACID. Remember the smaller the pKa, the STRONGER the acid
Define Acidosis and Alkalosis
Acidosis when pH in blood is lower than 7.35
Alkalosis when pH in blood is higher than 7.45
Respiratory Acidosis
Impairment of CO2 disposal. Common causes: Pulmonary disesase Barbituate overdose Servere pnuemonia
Respiratory alkalosis
Results from hyperventilation
Metabolic Acidosis
Overproduction of organic acids or inability of kidneys to excrete excess acid
- Diabetic ketoacidosis
- Lactic acidosis
- Diarrhea
