How does the strength of a base relate to its ability to accept protons?
How does the strength of a base relate to its ability to accept protons?
The strength of a base is determined by its effectiveness as a proton acceptor; strong bases are effective, while weak bases are not.
Explain why a concentrated weak acid can be equivalent to a diluted strong acid in terms of proton donation.
Explain why a concentrated weak acid can be equivalent to a diluted strong acid in terms of proton donation.
The equivalence arises because the strength of an acid is based on its tendency to donate protons, not its concentration; thus, a concentrated weak acid can yield a similar number of protons as a diluted strong acid.
Identify two strong bases and describe why they are classified as strong.
Identify two strong bases and describe why they are classified as strong.
Two strong bases are NaOH and KOH, classified as strong because they are excellent proton acceptors due to their complete ionization in water.

Study Notes
Strong Bases
- Strong bases readily accept protons (hydrogen ions).
- Examples include NaOH and KOH.
Weak Bases
- Weak bases are poor proton acceptors.
- An example is ammonia.
Concentration vs. Strength
- The terms "strong" and "weak" for acids and bases do not relate to concentration.
- A concentrated weak acid is equivalent to a diluted strong acid.
