Question

The titration of 6 mL of CsOH solution was carried out potentiometrically using

0.15 mol/L HCl solution. The equivalence point of the titration was found to be
12 mL. Calculate the CsOH concentration in the investigated solution. Write
schematically the integral potentiometric titration curve corresponding to the ti-
tration, if the EMF of the cell is given by an equation E = E° -0.059xpH, indi-
cate the position of the equivalence point on the graph.

Answer 1

The concentration of the CSOH solution can be calculated using the stoichiometry of the reaction and the volume of HNO3 at the equivalence point.

Step-by-step explanation:

The concentration of the CSOH solution can be calculated using the stoichiometry of the reaction and the volume of HNO3 at the equivalence point. The balanced equation for the reaction is:

CSOH + HNO3 → CSNO3 + H2O

From the volume of HNO3 added at the equivalence point, we can determine the number of moles of HNO3. Since the reaction is 1:1, this will also be the number of moles of CSOH. Then, we can divide the number of moles of CSOH by the volume of the CSOH solution to calculate its concentration.

Concentration of CSOH = Moles of CSOH / Volume of CSOH
