acids and bases Flashcards
1
Q
what is a conjugate base?
A
a species found when an acid loses a proton/hydrogen ion
2
Q
what is the pH formula?
A
pH= -log[H+]
3
Q
what are conjugate acid-base pairs?
A
a pair of reactants and products that are linked to each other by the transfer of a proton
4
Q
what is the definition of pH?
A
pH = -log[H+]
5
Q
what is a strong acid?
A
an acid that dissociates almost completely in aqueous solutions
6
Q
what is a weak acid?
A
an acid that partially (or incompletely) dissociates in aqueous solutions
7
Q
what happens if you dilute a strong acid 10x?
A
increases by 1
8
Q
what is a buffer?
A
a solution that minimises change in pH when small amounts of acid or base are added
9

what are acids?
A
proton donors
10
Q
