The formation constant for

$c AgCl (aq) = 4.9 . 10^{- 10} mol / L c (A g B r, a q) = 2.5 . 10^{- 5} mol / L c (A g l, a q) = 2 . 5^{- 7} mol / L$

Step by step solution

Define titration in halides.

Precipitation titration is a type of titration that involves precipitation at the end of the process. The precipitation method is used to titrate the majority of metallic halides. The argentometric titration method is also known as argentometric titration. In precipitation titration, there are three ways for determining the end point.

Calculate the temperature needed to achieve the fusion.

Find the logarithm of the formation.

$M (aq) + L (a q) 鈫� M L (a q) A g^{+} (a q) + C l^{-} 鈫� A g C l (a q); \log (K_{F}) = 3.31 {Ag}^{+} (a q) + B r^{-} 鈫� AgBr (aq); \log (K_{F}) = 4.46 A g^{+} (a q) + l^{-} 鈫� A g l (a q); l o g (K_{F}) = 6.6 Now formation constant is given as K_{F} = \frac{[M L]}{[M] [L]} \log (k_{F}) = \log [M L] - \log ([M]) - \log ([L])$

Calculate the formation constant.

$[M L] = [M] = [L] K_{F} = \frac{1}{[M L]} \log (K_{F}) = - \log [M L] (M L) = 10^{- \log (k_{f)}} calculate the concentrations of AgCl, AgBr and Agl . AgCl (A g C l, a q) = 10^{- l o g (k_{f)}} c (A g C l, a q) = 10^{- l o g (3.31)} c (A g C l, a q) = 4.9 . 10^{- 4} mol / L AgBr (A g B r, a q) = 10^{- \log (k_{f)}} c (A g B r, a q) = 10^{- \log (4.6)} c (A g B r, a q) = 2.5 . 10^{- 5} mol / L Agl : (A g l, a q) = 10^{- \log (k_{f)}} c (Agl, aq) = 2.5 . 10^{- 7} mol / L c (AgBr, aq) = 4.9 . 10^{- 4} mol / L Thus the formation constant for the following are c (A g B r, a q) = 2.5 . 10^{- 5} mol / L c (AgBr, aq) = 2.5 . 10^{- 7} mol / L$
