Question

Why does the number of H+ moles must equal to the number of OH moles at the end of titration?

Answer 1

Answer:

The mole ratio insures that the number of moles of H + ions supplied by the acid is equal to the number of OH − ions supplied by the base. This must be the case for neutralization to occur.

Answer 2

Explanation

TITRATION -

• A reaction in which a known solution is added to a solution of unknown volume to calculate its concentration.
• The titration reactions are generally neutralization reactions.
• Neutralization involves the quantification of acid and base to form a salt.
• At the neutral point, the concentration of hydrogen ions is in equilibrium with the concentration of hydroxide ions.
• In titration on the equilibrium of the ions, the solution becomes neutral with pH 7.
• In order to determine the endpoint of the titration, an indicator is added that changes color distinctly in acidic and basic solutions.
• When the moles of hydrogen ions and hydroxide ions are equal it is known as the equivalence point that comes before the endpoint in the titration.
