    You use reaction with Nh3+ hcl = nh4+ + cl- and Nh4OH- Nh4+ +Oh-

    eduncle-logo-app

    nh4cl why

    eduncle-logo-app

    nh3 aur HCl ki dissociation hi ri hai n

    eduncle-logo-app

    yha mix kiya gya hai na Ammonia solution me Hcl ko

    eduncle-logo-app

    jo neutralised ho rhe hai nh3 se hcl or nh4cl form ho rhe hai or Nh3 jo remain un neutalised reh gye hai wo rahenge...then we use common ion effect

    eduncle-logo-app

    Nahi aab jaise ch3cooh aur ch3 coona

    eduncle-logo-app

    lelo

    eduncle-logo-app

    see isme to direct dikhre hai. ki ch3 coo na interfere kr rha in conce. of ch3 coo -

    eduncle-logo-app

    haa ...same hai na yha pe nh4cl form ho rhe hai ye dissociate honge nh4+ or cl- me..or nh3 and h20 hai jo solution me remain hai..so common ion effect lg rha hai

    eduncle-logo-app

    weak hai tbhi na lg rhe hai...yha nh3 weak hai jo isko suppress krenge nh4+ ion nh4cl se

    eduncle-logo-app

    sir nh4 cl salt hai aab ye JB BN gye hain fr kyun dissociate honge

    eduncle-logo-app

    aise to fr nacl JB bnaya vo bhi dissociate hoga

    eduncle-logo-app

    nhi yha question ke according hi na...nh3 se hcl neutalise jo remian bache or jo form hue....nh3 kuch bach gye or nh4cl form hue

    eduncle-logo-app

    sir

    NH4Cl is salt na

    eduncle-logo-app

    NH4Cl will exist as NH4+ + Cl-

    eduncle-logo-app

    NH3 + H2O = NH4+ + OH-

    eduncle-logo-app

    sir nh4 cl kyun use krna dissociation to nh3 aur HCl Ka hi Hoga n

    eduncle-logo-app

    Solution me NH3 water & HCl . After titration you have NH4Cl NH3 & H2O

    eduncle-logo-app

    Now NH3 is a weak base so common ion effect lagega

    eduncle-logo-app

    ok

    eduncle-logo-app

    check this yhan to simple common ion effect dikh rha

    eduncle-logo-app

    fr vhan kyun ni

    eduncle-logo-app

    mai samajha nahi

    eduncle-logo-app

    waha par bhi to common ion effect hai

    eduncle-logo-app

    ok sir I solved this question thanks

    eduncle-logo-app

    you are welcome
