shit you don't know Flashcards
Ka*Kb=
10^-14
what is water capable of doing
autoionization therefore in equilibrium ka= kw (10^-14)
pH is the logarithm of the hydronium ions
pH= -log(H3O+)
red litmus paper turns what color when it is in contact with base
blue
buffers can be
a weak acid with its conjugate base
a weak base with its conjugate acid
weak acids
HF, CH3COOH (acetic acid), HCN, HNO2, H2CO3, H2SO3, H3PO4, (COOH)2
weak base
ammonium NH3, hypochlorite ion, carbonate ion, hydrosulfide ion, methylamine, hydroxylamine, pyridine
how do buffers work
when a strong acid is added the base neutralizes the H3O+ ions
when a strong base is added the acid neutralizes the OH- ions
what is needed for a buffer to be the most effective
the number of moles of the weak acid and its conjugate base must be large and vice versa compared to the strong acid or base that is being added
buffer that maintains the blood pH
H2CO3+H2O–> HCO3-+H30+
pH of the blood is maintained around
7.4
what happens if the pH goes any lower than 6.8 or above 7.8
our cells will begin to denature
Ka is the
acid ionization constant or acid dissociation constant
Ka»>1 is a
strong acid because you will more readily ionize therefore there will be more products versus the reactants
stronger acid makes for a
weaker conjugate base
ka«<1 is a
weak acid
water is amphoteric therefore it can
act as an acid or a base
Kw is the
autoionization constant
autoionization of water equation
[H3O+][OH-]. you ignore the starting water because it is pure water
concentration of hydronium and hydroxide in water at standard temp
1*10^-7
you have such low concentration of ions in autoionization because
it is equal to 1*10^-14 making the ka very very small
ph=
-log(H3O+)
scientific notation if you have positive integer
move to the right
Scientific notation if you have negative integer
move to the left
HF is what kind of acid
a weak acid because it binds strongly to the Flourine atom therefore it is less likely to give up its hydrogen
HI is the strongest
acid in the halogen group then follows HBr then HCl
strong acids
HClO4, HX(Br, I, Cl), H2SO4, HNO3
strong bases
NaOH, KOH, Ca(OH)2, Mg(OH)2
when you lose a leaving group you want it to
be stabilized by electron donating groups
lower the pka the
stronger acid
ammonia is a
weak base
ammonium ion
NH4+ is an acid
pka+ pkb=
14
salts from a strong acid and a strong base forms what kind of solution
a neutral solution
salt with a weak acid and strong base will form
basic solutions that are greater than 7
salt with strong acid and weak base
will give you an acidic solution
common ion effect if you add an acetate ion then
this will increase the amount of acetate ion and therefore will increase in the opposite direction and increase the pH because less H3O is being formed
what equation do you use for buffer calculations
henderson- hasselbach
log 1=
0
the three component weberian theory
with class, power, and status all being important wealth power prestige influence the way in which people treat one another
substance use is a diagnostic criterion of
Bipolar disorder
personality disorders are seen as
relatively stable over an individuals life
number of births per 1000 is
birth rate
fertility rate is
number of children per woman
social capital
is the value embedded in social networks which includes connections, job leads, the availability to aid in a crisis and so forth
Cultural capital
encompasses non-financial factors that lead to social mobility, such as knowledge of styles and manners of speech, appearance, and charisma. It does not include the value of social networks, though having strong social networks can help in acquiring it
false consensus
means that people tend to overestimate how common their behavior is and assume that others do the same thing that they do
self-serving bias
is a tendency to make attributions that protect our self-esteem
fundamental attribution error
is the tendency for people to attribute the behavior of others to internal, stable, underlying personality traits
actor-observer bias
is the tendency to attribute our own behaviors externally while attributing others’ behaviors internally
anomie
describes the breakdown in social bonds in modern society which is the result of the social norms and reciprocity
external validity
involve application of the study to outside situations
transtheoretical change model
describes the different stages a person goes through when making decisions. pre-contemplation, contemplation, preparation, action and maintenance
client centered therapy
emphasizes collaboration between practioner and client and the client relationship
dialectical-behavioral therapy
emphasizes regulation of affect and interpersonal effectiveness
how long does short term memory last
15-30 seconds unless it is actively rehearsed
Bipolar I
has severe manic states while bipolar II does not
normative conformity
describes a situation in which a person does something to fit in or be liked
identification
is when a person changes the way they act to fill a social role
compliance
when a person publicly agrees but privately does not
anterograde amnesia
refers to when a person loses the ability to create memories after the event that caused the amnesia
retrograde amnesia
is the inability to recall past memories. happened before an event

The psychological phenomenon that causes some people to see or hear a vague or random image or sound as something significant
abasia
is the inability to walk possibly due to some psychological shock or trauma
parapraxis
is a slip of the tongue that might reveal something that is actually desired
mediating factor
explains between one factor and another
meta-cognition
involves being able to think about thinking and enables an individual to observe his own processes to learn from them
primary prevention
refers to prevention of a disease or problem area before any signs, symptoms, or risk behaviors have developed
secondary prevention
when there is already a present illness or problem that needs to be prevented
tertiary prevention
is prevention of a disease from getting any worse
social facilitation
the tendency to perform better when there is a group watching you(if you are good at the task)
false consciousness
refers to internalizing oppressive narratives regarding unjust social structures

posists that when people are prevented from achieving through culturally approved through institutional means they experience strain that can lead to deviance. retreativist retreat when their behavior is unacceptable (alcoholism or drug addiction)
