What is an acid-base reaction? List an example and identify the acid and the base.
Acid-Base reaction is a chemical reaction where an acid and base are participate together. They interact with each other to neutralise the properties of acid and base by producing a salt and water. The acid-base reaction is represented as follows.
Acid (aq) + Base (base) ------> salt + Water
For example: The reaction between sulfuric acid (H2SO4) and Potassium hydroxide (KOH) produces potassium sulfate ( K2SO4) and water.
H2SO4(aq) + 2KOH(aq) ------> K2SO4 (aq) + H2O(l) -----(1)
Acid Base Salt Water
Here, Acid is a substance which produces H+ or H3O+ ions in aqueous solution whereas base is substance which produces OH- ions in aqueous solution.
H2SO4(aq) ------>H+(aq) + HSO4-(aq)
HSO4-(aq)-------> H+(aq) + SO42-(aq)
So, in the above reaction H2SO4(aq) is an acid.
KOH(aq) ----->K+(aq) + OH-(aq)
So, in the above reaction KOH(aq) is a base.
