Respuesta :
Strong acid on combining with strong base will always give neutral solutions. Consider the following example for the same
HCl + NaOH ↔ NaCl + H2O
(strong (strong
acid) base)
In above case, the resultant solution is neutral in nature.
On other hand, weak acid will react with strong base to form salt and water. But the solution will be basic in nature. Also, strong acid will react with weak base to form salt and water. But the solution will be acidic in nature
HCl + NaOH ↔ NaCl + H2O
(strong (strong
acid) base)
In above case, the resultant solution is neutral in nature.
On other hand, weak acid will react with strong base to form salt and water. But the solution will be basic in nature. Also, strong acid will react with weak base to form salt and water. But the solution will be acidic in nature
The acid-base pair will always undergo a reaction that produces a neutral solution is a strong or weak acid-base pair.
What are acids and bases?
According to the Arrhenius theory, acids are those species which gives H⁺ ion in the solution and bases are those species which gives OH⁻ ion in an aqueous solution.
Further more acids and bases are also classified as:
- Strong acids and bases which show complete dissociation in an aqueous solution.
- Weak acids and bases which show partial dissociation in an aqueous solution.
As we know that acids and bases on reacting with each other produces water and its salt as:
Acid + Base → Water + Salt
So, when the reaction between two strong acids and bases or between two weak acids and bases takes place then we get neutral solution.
So, strong or weak acid-base pair produces neutral solution.
