Question

how are strong bases different from weak bases?
weak bases have a higher ph value.
strong bases fully dissociate in water.
weak bases react faster with acids.
strong bases stay together more than they split.

Explanation:

• pH value: pH depends on concentration, not just strength. A dilute strong base could have a lower pH than a concentrated weak base.
• Dissociation: By definition, strong bases fully dissociate in water (\(B + H_2O

ightarrow BH^+ + OH^-\) goes to completion), while weak bases only partially dissociate (\(B + H_2O
ightleftharpoons BH^+ + OH^-\), equilibrium lies to the left).

• Reaction rate with acids: Strong bases, having more \(OH^-\) ions (due to full dissociation), generally react faster with acids (neutralization \(H^+ + OH^-

ightarrow H_2O\) is very fast for strong - base - derived \(OH^-\)). But if concentration is considered, a very concentrated weak base (with more \(B\) that can accept \(H^+\) over time) could react, but the initial rate (due to available \(OH^-\)) is higher for strong bases.

• Dissociation description: Strong bases split completely (dissociate fully), not stay together.

Answer:

Strong bases fully dissociate in water.
