What is the difference between a strong base and a weak base?

Answer 1

a strong base produces more ions in solution than a weak base-apex

Answer 2

A "strong" acid (or base) is one that dissociates completely in dilute aqueous solution. One which does not is a "weak" acid (or base). An acid with a pKa (or a base with a pKb) lower than about -2 is considered to be a "strong" acid.

Weak acids and bases can still be quite corrosive. HF is a "weak" acid with a pKa of around 3.2 (which corresponds to only about one molecule out of every 38 or so being dissociated), but it's pretty terrible stuff and will dissolve even glass.

Answer 3

A strong base completely dissociates in water to produce hydroxide ions, resulting in a high concentration of hydroxide ions in solution. In contrast, a weak base only partially dissociates in water, leading to a lower concentration of hydroxide ions. Strong bases have a higher pH compared to weak bases.

Answer 4

==== A strong base is a base that dissociates completely into a metal ion and hydroxide ion (or nearly so) in aqueous solution. A weak base is a base that dissociates only slightly in aqueous solution.

Answer 5

A weak base comes from a strong acid (when the acid loses a proton or accepts an electron pair). A strong base comes from a weak acid. Generally, acid strength increases with electronegativity and size.

Answer 6

Strong bases are those with very large dissociation constants. Weak bases are those with very low dissociation constants. They get these because strong bases are usually hydroxide salts; all hydroxides are quite soluble, so the majority of hydroxide is released into solution. A weak base is normally a Bronsted-Lowry base, in that it doesn't add hydroxide so much as remove hydronium. Because this is a relatively inefficient arrangement thermodynamically speaking, not many hydronium ions will react this way and so will remain in solution rather than be neutralised.

Answer 7

The difference between these two are simple. The strong bases pick on the weak bases and call them gay. However, in reality, the strong bases are in fact the ones that are gay. It's a pretty bizarre thing huh?

Answer 8

strong acids completely dissociate in water

Answer 9

Strong bases break up in solution. They producemore OH- ions than equal concentrations of weak bases.

Answer 10

strong bases can abstract proton easily where as weak base can't
