What is the concentration of silver ions where silver iodide, Agl, is in a solution of hydroiodic

jonny [76]

Answer:

$[Ag^+]=2.82x10^{-4}M$

Explanation:

Hello there!

In this case, for the ionization of silver iodide we have:

$AgI(s)\rightleftharpoons Ag^+(aq)+I^-(aq)\\\\Ksp=[Ag^+][I^-]$

Now, since we have the effect of iodide ions from the HI, it is possible to compute that concentration as that of the hydrogen ions equals that of the iodide ones:

$[I^-]=[H^+]=10^{-3.55}=2.82x10^{-4}M$

Now, we can set up the equilibrium expression as shown below:

$Ksp=8.51x10^{-17}=(x)(x+2.82x10^{-4})$

Thus, by solving for x which stands for the concentration of both silver and iodide ions at equilibrium, we have:

$x=[Ag^+]=2.82x10^{-4}M$

Best regards!

C3H8 and CH4 are 2 compounds made from the same elements. This is an example of which law? A) Law of Conservation of Mass b) Law

Sphinxa [80]

C3H8 and CH4 are two compounds made from the same two elements, C and H. The ratios of C and H for both are round numbers.

Law of multiple proportions states that when two elements combine with each other to form more than one compound, the weights of one element that combine with a fixed weight of the other are in a ratio of small whole numbers.

So the ans is C) Law of Multiple Proportions
