Flashcards in Water, Weak Acids & Bases Deck (16):
1

Name the 3 strongest bonds in order

1. Ionic (e transfer)
2. Covalent (e sharing)
3. metallic (glue)

2

What 3 elements can form a H bond?

N,O,F

3

List these bonds in order of strength (Ion Dipole, Dipole dipole, H bond & Dipole induced dipole)

1. Ion dipole
2. H bond
3. Dipole dipole
4. Dipole induced dipole

4

How many water molocules does a h2o molocule bind to in liquid sate? Solid sate?

Liquid: 3.4
Solid: 4

5

What does AMPHIPATHIC mean?

AKA: Amphiphillic having both hydrophobic and hydrophilic parts

6

Label each symbol in the equation:
∆G = ∆H - T∆S

∆G = Gibbs free energy
∆S = Entropy
∆H = Enthalpy
T = Temperature

7

What are the 4 coliigative properties?

1. vapor pressure
2. boiling point
3. melting point
4. osmotic pressure

8

What happens to a cell in a Hypotonic/Hypertonic solution?

Hypotonic: Water rushes into cell, cell swells
Hypertonic: Water leaves cell, cell shrinks

9

Define an acid and a base

Acid: H+ DONORS
Base: H+ ACCEPTOR

10

What is pKa?

pKa is the pH in which the acid and the Base are in the same concentration.

11

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

12

Define Acidosis and Alkalosis

Acidosis when pH in blood is lower than 7.35

Alkalosis when pH in blood is higher than 7.45

13

Respiratory Acidosis

Impairment of CO2 disposal.
Common causes:
Pulmonary disesase
Barbituate overdose
Servere pnuemonia

14

Respiratory alkalosis

Results from hyperventilation

15

Metabolic Acidosis

Overproduction of organic acids or inability of kidneys to excrete excess acid

-Diabetic ketoacidosis
-Lactic acidosis
-Diarrhea

16

Metabolic alkalosis

Abnormal loss of acid from the body

-Severe vomitin
-Excess gastric suctioning
