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

This video describes how to draw the conductometric titration curve for a strong acid with a weak base (hydrochloric acid/HCl 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.
Before titration - only HCl present.
Presence of H+ with high ionic conductivity - high conductance
During titration till equivalence point /neutralisation point-
H+ with high ionic conductivity is replaced by NH4+ with low ionic conductivity - conductance decreases
At equivalence point/neutralisation point - NH4Cl and H2O are present
least conductance
After equivalence point - excess NH4OH is added
does not dissociate due to common ion effect - conductance remains constant

Mam plz tell me,kya 1)conductivity increase hota hai and then remains same in case strong acid weak base,OR ....2)conductivity decrease hota hai and then remain same in case of strong acid, weak base....
As graph shows conductivity decrease(..because graph is down ward ),it means conductivity decrease
But on the other hand we have take strong acid (Hcl)
Strong acid means it dissociate complete,when it dissociate completely,it means it produce large no.of ions ,conductivity must be increased,but we also know the H+ produce in strong acid is absorbed by oH-, plz tell me which one is correct first start statement or 2nd statement as write me in starting, p lzzzzz reply fast,I'm waiting......

You did not watch the video properly. The explanation is clearly given. Your second statement is correct. Slow moving(low ionic conductivity) Na+ ions are replacing the fast moving H+ ions( high ionic conductivity) when HCl is titrated with NaOH. So conductivity decreases. Watch the video carefully again.
