EXPERIMENT : CONDUCTOMETRIC TITRATION OF A MIXTURE OF ACIDS WITH A STRONG BASE
I want the analysis for this experiment

Transcribed Image Text:Calculations:
For HCl:
Given the volume of the strong acid (HCI) = 15
M1= 0.01 M
From the experimental data:
Volume of NaOH (V1) = 14 ml
M1XV1
0.01 x14
So, the molarity of HCI =
15
= 9.333 x 10-3 M
15
molarity of HCI = 9.333 x 10-3 M
For weak acid ( CH3COOH ):
Given the volume of the weak acid (CH3COOH) = 15
M1= 0.01 M
From the experimental data:
Volume of NaOH (V2) = 18 ml
So, the molarity of CH3COOH =
М1x(V2-V1)
0.01 x(18-14)
= 2.666 x 10-3 M
15
15
molarity of CH3COOH = 2.666 × 10-3 M
