How is the reaction of weak base and strong acid?

Answer 1

Depends what the two solutions are.....but the classic example is

hydrochloric acid and sodium hydroxide.

HCl + NaOH === NaCl + H2O

This is a neutralization reaction that produces a salt called sodium chloride (table salt) and water.

Answer 2

ACID + BASE --> SALT + WATER

Generally in aqueous solutions, an acid is a negative ion with a hydrogen ion. The hydrogen ion, H+, is called a proton. Strong acids donate lots of these protons to the aqueous (water) solution.
Often a base has a hydroxide ion, OH-, that can react with the hydrogen ion to make water. A strong base donates lots of hydroxide ions.
Acids have negative ions with a positive hydrogen ion and bases are a positive ion with a negative hydroxide ion. HA + MOH --> MA + H2O
HA is the acid - hydrogen ion with an anion (anion is the term for a negative ion)
MOH is the base - hydroxide with a metal cation (cation is the term for a positive ion)
MA is the salt - an anion and a cation (that's almost the chemistry definition for a salt)

The anion and the cation really don't do anything so chemists call them spectator ions. They are put together when the reaction is written but that's just to keep track of them.
The complete reaction would look like this.
H+(aq) + A-(aq) + M+(aq) + OH-(aq) --> H2O(l) + M+(aq) + A-(aq)
That extra anion and cation haven't changed. They are called spectator ions.

But the net ionic reation is:
H+(aq) + OH-(aq) --> H2O(l)

The mechanism for a base with out a hydroxide ion is slightly different but the net ionic reaction stays the same.

Strong acids: sulfuric, hydrochloric or nitric acids
H2SO4; HCl; HNO 3
Strong bases: sodium hydroxide, potassium hydroxide
NaOH; KOH

Answer 3

As the anion of the salt undergoes hydrolysis, the resultant solution becomes weakly acidic.
