Bronsted-Lowry bases donate protons.
False.
They accept protons.
When HCl is dissolved in water, the resulting products are:
H3O+ and Cl–.
Which acid is responsible for reacting with limestone and eating away statues and buildings?
Sulfuric acid.
Use the information below to determine which one of the following weak
acids is the strongest.
HCN (Ka = 4.9 × 10^-10)
HClO (Ka = 3.0 × 10^-8)
HNO2 (Ka = 4.5 × 10^-4)
HF (Ka = 6.8 × 10^-5)
HNO2 (Ka = 4.5 × 10^-4)
Ka values closer to 1 are stronger acids.
Use the information below to determine which one of the following weak
acids is the weakest.
HCN (Ka = 4.9 × 10^-10)
HClO (Ka = 3.0 × 10^-8)
HNO2 (Ka = 4.5 × 10^-4)
HF (Ka = 6.8 × 10^-5)
HCN (Ka = 4.9 × 10^-10).
Weak acids have values farther away from 1.
Use the information below to determine which of the following weak
acids has the strongest conjugate base.
HCN (Ka = 4.9 × 10^-10)
HClO (Ka = 3.0 × 10^-8)
HNO2 (Ka = 4.5 × 10^-4)
HF (Ka = 6.8 × 10^-5)
HCN (Ka = 4.9 × 10^-10).
The weakest acids have the strongest conjugate bases.
Use the information below to determine which of the following weak
acids has the weakest conjugate base.
HCN (Ka = 4.9 × 10^-10)
HClO (Ka = 3.0 × 10^-8)
HNO2 (Ka = 4.5 × 10^-4)
HF (Ka = 6.8 × 10^-5)
HNO2 (Ka = 4.5 × 10^-4).
The strongest weak acid will have the weakest conjugate base.
Match each solution below with whether it is acidic, basic or neutral:
- [H3O+] = 1.4 x 10^-9 M.
- [H3O+] = 2.0 x 10^-5 M.
- [H3O+] = 1.0 x 10^-7 M.
- Basic (because H3O+ is more than 10^7).
- Acidic (because H3O+ is less than 10^7).
- Neutral (because H3O+ = 10^7).
Match each solution below with whether it is acidic, basic or neutral:
- [OH–] = 8.0 x 10^-3 M.
- [OH–] = 1.0 x 10^-7 M.
- [OH–] = 3.5 x 10^-10 M.
- Basic (because OH- is less than 10^7).
- Neutral (because OH- = 10^7).
- Acidic (because OH- is more than 10^7).
