ph Flashcards
when is a solution a acid?
when ph is less then 7
when is a solution a natural?
when ph is 7
when is a solution a base?
when ph is grater then 7
how do you convert concertation to ph?
PH= -log10(concertation)
how do you calculate total dispersion?
Kw=Ka + Kb
what does Kw mean?
the total dissociates
what is the value of kw?
1x10^-14
does acid give or take proton ?
acid gives protons
does base give or take proton ?
basses take proton
what is polyprotic?
can donate more than one hydrogen ion
what is monoprotic?
can donate one hydrogen ion
what happens when an acid dissolves in water?
donates a hydrogen
what does water contain?
small but amount of equal H3O+ and OH-
what does dissociates mean?
split into separate smaller atoms, ions, or molecules
what do diprotic acid do in water?
dissolves
what happens to the acidity when a solution dissociates?
the weaker it gets
what does stronger mean?
the strength of the acid
is HCl a strong or weak acid?
strong
is acetic a strong or weak acid?
weak
what does contracted mean?
more particles in the solution
what does dilute mean?
less particles in a solution
does more dissociation mean it is stronger or weaker?
stronger
what type if acids partially dissociate?
weak acid
which acids completely dissociate?
strong acid
what is the most conductive acid or base?
strong acid or base
how can you determine if it is a acid?
[H+]>[OH-]
how can you determine if it is a base?
[OH-]>[H+]
