Determine the concentration of nh3(aq) that is required to dissolve 743 mg of agcl(s) in 100.0 ml of solution. the ksp of agcl is 1.77Ã 10â10.

1.1 M

Explanation:

The dissociation of is as follows:

Given Value for

The equation for the reaction for the formation of complex ion is :

The value of

If we combine both equation and find the overall equilibrium constant will be:

If = x M

The solubility of   in the solution will be:

Constructing an ICE Table; we have :

Initial  (M)                                     x                   0                      0

Change  (M)                       -2 (0.0518)      + 0.0518          + 0.0518

Equilibrium (M)                    x - 0.1156          0.0518             0.0518

Equilibrium constant;

(K) =

x = [NH₃] =  1.089 M

[NH₃] ≅ 1.1 M                

n has four pairs of electrons in the valence shell, electrons repel one another ,n has 7 protons in its nucleus, and since n has 7 protons, it must fill the second shell, giving it 4 pairs of electrons. the electrons form 3 bonds and 1 lone pair of electrons. each pair of electrons repels the other pairs, so they are equally far apart.

so all of the above

a  solution  is always transparent, light passes through with no scattering from solute particles which are molecule in size. the  solution  is homogeneous and does not settle out. a colloid is intermediate between asolution  and a  suspension. while asuspension  will separate out a colloid will not.
