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

This video describes how to draw the conductometric titration curve for a strong acid with a strong base (hydrochloric acid/HCl vs sodium hydroxide/NaOH). It explains about the Conductometry, Principle of Conductometric titration. It explains how to draw the conductometric titration curve for the strong acid with a strong 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.
conductance is due to the movement of ions in the solution
one ion replaces with another ion of different ionic conductivity during the titration
equivalence point is determined graphically.
Before titration – only HCl present. During titration till equivalence point /neutralisation point–
H+ with high ionic conductivity is replaced by Na+ with low ionic conductivity – conductance decreases
At equivalence point/neutralisation point – NaCl and H2O are present
After equivalence point – excess NaOH is added
accumulation of OH - with high ionic conductivity – conductance increases
least conductance
Presence of H+ with high ionic conductivity – high conductance
