titration game

At equivalence point of any titration, the solution contains:

• The salt only

• The titrant and the analyte

• The titrant and the salt

• The titrant only

Identify the titrant and the analyte

• Analyte: Sa

  Titrant: Sb

• Analyte: Wa

  Titrant : Sb

• Analyte: Sb

  Titrant: Wa

• Analyte: Wb

  Titrant: Sa

When CH3COOH is titrated with NaOH, the pH at equivalence point may be:

• 5

• 6.2

• 7

• 8.4

When NH3 reacts with HCl, the solution contains ------- at equivalence point

• Basic salt

• neutral salt

• Acidic salt

• NH3 and acidic salt

The pH in the red zone is calculated through:

• pH = pKa

• Hendersson equation

• pOH = -log [sb]

•
