Acids And Bases Flashcards
1
Q
Acid
A
Tastes sour (lemons), reacts with metals, turns pH Indicator paper red, neutralizes bases
2
Q
Base
A
Tastes bitter (cleaning products), feels slippery, turn pH Indicator paper blue, neutralizes acids
3
Q
Conjugate base
A
The pair of an acid
4
Q
Conjugate acid
A
The pair of a base
5
Q
pH
A
A measure of hydrogen ions
Scale that goes from 0 to 14
pH less than 7 -> acid
pH equal to 7 -> neutral
pH greater than 7 -> base
6
Q
pOH
A
A measure of hydroxide ions
7
Q
Amphoteric
A
A substance that can act as either an acid or a base
8
Q
Ion product constant of water
A
In pure water, the concentrations of hydronium ions [H3O+], and hydroxide ions [OH-], are equal
[H3O+] = [OH-] = 1x10^-7 M
9
Q
Neutralization
A
When acids and bases combine
10
Q
Indicators
A
substance that changes color in an acid or base
