Conductometric titration of weak acid and weak base (weak acid vs weak base)/Conductometry

This video describes how to draw the conductometric titration curve for a weak acid with a weak base (acetic acid/CH3COOH vs ammonium hydroxide/NH4OH). It explains about the Conductometry, Principle of Conductometric titration. It explains how to draw the conductometric titration curve for the strong acid with a weak base. Introduction of Conductometry, Conductance, advantages and disadvantages of conductometric titration, applications of conductometric titration.
Conductometric titration is a titration used to measure the amount of an analyte present in the given solution by measuring the change in the conductance as a function of volume of titrant.
Conductometric titration(weak Acid Vs Weak Base)
CH3COOH & NH4OH- does not dissociate easily
CH3COONH4 - dissociates better than CH3COOH
NH4+ - has low ionic conductivity
Before titration - only CH3COOH present
CH3COOH does not dissociate easily - low conductance
Initial addition of NH4OH - CH3COOH and small amount of CH3COO NH4+
CH3COOH does not dissociate easily due to common ion effect of CH3 COO- - slight decrease in conductance
During titration till equivalence point /neutralisation point-
CH3COONH4+ ionises better than CH3COOH - conductance increases slowly
At equivalence point/neutralisation point - CH3COO- and NH4+ are present
Conductance increases
After equivalence point - excess NH4OH is added
does not dissociate due to common ion effect - conductance remains constant

Good work

Thank you

[@sooji2406]

can you clarify or explain in-depth why there is a small dip during the initial addition of NH4OH

[@RevathiPurushothaman]

Due to common in effect

[@pulukurijagadeesh5646]

Tq mam

[@RevathiPurushothaman]

Most welcome.

[@rachanashetty109]

Mam pls make a video on POC and medical chemistry

[@RevathiPurushothaman]

Sure.

[@bangarulakshmireddi8306]

Mam please explain simply the process of experiment

[@RevathiPurushothaman]

I have simultaneously explained the process and effect with a graph directly.
