Answer 1

Answer:

I can't understand tell brief

Answer 2

The principles that pH-metric titration works on are-

• pH can be defined as the negative logarithm of H ion activity.

                pH = -log [H+]

• Initial pH is dependent on the initial concentration of strong acid. As the strong base is added the pH increases slowly.
• The pH of the solution before the equivalence point increases quickly.
• Athe the point of equivalence the number of moles of acid is equal to the number of moles of base stoichiometrically.
• The pH after the equivalent point is determined by the concentration of excess NaOH.
