New cards
Acid (as defined in this unit)
A substance that produces H⁺ ions when dissolved in water: HX → H⁺(aq) + X⁻(aq)
2
New cards
Base (as defined in this unit)
A substance that produces OH⁻ ions when dissolved in water: MOH → M⁺(aq) + OH⁻(aq)
3
New cards
Another name for an acid-base reaction
Neutralization reaction
4
New cards
Net ionic equation for strong acid + strong base
H⁺(aq) + OH⁻(aq) → H₂O(l)
5
New cards
Hydronium ion
H₃O⁺ – the form H⁺ takes in water (H⁺ attached to a water molecule)
6
New cards
Strong electrolyte
Dissociates completely into ions in water; conducts electricity well (bright bulb)
7
New cards
Weak electrolyte
Only partially dissociates, giving few ions; conducts poorly (dim bulb)
8
New cards
Strong acids (6)
HCl, HBr, HI, HNO₃, H₂SO₄, HClO₄
9
New cards
Strong bases (5)
NaOH, KOH, Ca(OH)₂, Sr(OH)₂, Ba(OH)₂
10
New cards
Weak acids (examples)
HF (hydrofluoric), H₃PO₄ (phosphoric), CH₃COOH (acetic)
11
New cards
Weak base (example)
NH₃ (ammonia)
12
New cards
Name and formula: HCl
Hydrochloric acid – strong acid
13
New cards
Name and formula: HBr
Hydrobromic acid – strong acid
14
New cards
Name and formula: HI
Hydriodic acid – strong acid
15
New cards
Name and formula: HNO₃
Nitric acid – strong acid
16
New cards
Name and formula: H₂SO₄
Sulfuric acid – strong acid
17
New cards
Name and formula: HClO₄
Perchloric acid – strong acid
18
New cards
Name and formula: HF
Hydrofluoric acid – WEAK acid
19
New cards
Name and formula: H₃PO₄
Phosphoric acid – WEAK acid
20
New cards
Name and formula: CH₃COOH
Acetic acid – WEAK acid
21
New cards
Weak acid dissociation equation
HX(aq) ⇌ H⁺(aq) + X⁻(aq) (reversible arrow – equilibrium)
22
New cards
Ammonia reacting with water
NH₃(aq) + H₂O(l) ⇌ NH₄⁺(aq) + OH⁻(aq)
23
New cards
How do you write strong acids/bases in ionic equations?
As separated ions (they dissociate completely)
24
New cards
How do you write weak acids/bases in ionic equations?
As intact molecules (they mostly don't dissociate)
25
New cards
Molecular equation: HCl(aq) + KOH(aq) →
HCl(aq) + KOH(aq) → KCl(aq) + H₂O(l)
26
New cards
Total ionic equation: HCl + KOH
H⁺(aq) + Cl⁻(aq) + K⁺(aq) + OH⁻(aq) → K⁺(aq) + Cl⁻(aq) + H₂O(l)
27
New cards
Net ionic equation: HCl + KOH
H⁺(aq) + OH⁻(aq) → H₂O(l)
28
New cards
Spectator ions in HCl + KOH
K⁺ and Cl⁻
29
New cards
Gas-forming acid-base reaction: NaHCO₃ + CH₃COOH (molecular)
NaHCO₃(aq) + CH₃COOH(aq) → NaCH₃COO(aq) + CO₂(g) + H₂O(l)
30
New cards
Total ionic: NaHCO₃ + CH₃COOH
Na⁺(aq) + HCO₃⁻(aq) + CH₃COOH(aq) → Na⁺(aq) + CH₃COO⁻(aq) + CO₂(g) + H₂O(l)
31
New cards
Net ionic: NaHCO₃ + CH₃COOH
HCO₃⁻(aq) + CH₃COOH(aq) → CH₃COO⁻(aq) + CO₂(g) + H₂O(l) (Na⁺ is the spectator)
32
New cards
Why is CH₃COOH written as a molecule in the ionic equation?
It is a weak acid – only slightly dissociated
33
New cards
Observation in gas-forming acid-base reaction
Bubbling/fizzing as CO₂(g) is released
