2.1.4: Acids Flashcards
1
Q
Weak acid:
A
- Partially dissociates
* e.g. CH₃COOH ⇌CH₃COO⁻ + H⁺
2
Q
Strong acid:
A
- Fully dissociates
* e.g. HCl ⟶ H⁺ + Cl⁻
3
Q
Bronsted-Lowry base
A
A proton acceptor
4
Q
Bronsted-Lowry acid
A
A proton (H⁺) donor
5
Q
What is a monoprotic acid?
A
Donates 1 proton
6
Q
Typical properties of acids
A
- Usually taste sour
- pH less than 7
- Aqueous solutions of acids contain H⁺ ions
- Acid = proton (H⁺) donor
7
Q
Ionic equation for neutralisation reaction
A
H⁺ + OH⁻ ⟶ H₂O
8
Q
Acid + base
A
Acid + base ⟶ salt + water
9
Q
Acid + carbonate
A
Acid + carbonate ⟶ salt + water + carbon dioxide
10
Q
Acid + metal
A
Acid + metal ⟶ salt + hydrogen
11
Q
Acid + metal oxide
A
Acid + metal oxide ⟶ salt + water
12
Q
Acid + metal hydroxide
A
Acid + metal hydroxide ⟶ salt + water
13
Q
Conjugate base
A
The base that accepts the proton donated by the acid.
e.g. Cl⁻ in HCl
14
Q
Concentrated acid
A
Fewer water molecules per unit volume than a dilute acid.
15
Q
Acids release __ ions into solution
A
H⁺
