For Which Of The Mixtures Will Ag2so4 S Precipitate

Which of the following ag2SO4 compounds fails? ۔

150.0 ml 0.10 M Na2SO4 (water) and 5.0 ml 0.20 M AgNO3 (water)

150.0 ml 0.10 M Na2SO4 (water) and 5.0 ml 0.30 M AgNO3 (water)

150.0 ml 0.10 M Na2SO4 (water) and 5.0 ml 0.40 M AgNO3 (water)

150.0 ml 0.10 M Na2SO4 (water) and 5.0 ml 0.50 M AgNO3 (water)

If I get the correct answer, please tell in detail. Thank you very much!

The soluble uct for Ag2SO4 is Ksp = 1.4 * 10 5.

The definition of Ksp is Ksp = [Ag +] ² * [SO4 2]

For each solution, calculate [Ag +] and [SO4 2]

If UCT <Ksp is formed. Will not hurry

Na2SO4 (aqueous) + 2AgNO3 (aqueous)> Ag2SO4 (s?) + 2NaNO3 (aqueous)

A mole of Na2SO4 reacts with AgNO3 to form a mole of Ag2SO4.

Mole ratio Ag2SO4 / AgNO3 = 1/2.

150 ml 0.10 m Na2SO4 = 0.0150 mol Na2SO4.

5.0 ml 0.20 M AgNO3 = 0.001 mol AgNO3.

AgNO3 is a finite reagent, so 0.001 mol reacts to form 0.0005 mol of Ag2SO4.

In 155 ml of solution, then

[Ag2SO4] = 0.003226 M

Then

[Ag +] = 0.006452 M

[SO4 2] = 0.003226 M

0.006452² * 0.003226 = 1.34 * 10 7.

<Ksp, so that there is no rain.

150 ml 0.10 m Na2SO4 = 0.0150 mol Na2SO4.

5.0 ml AgNO3 0.30 M = 0.0015 mol AgNO3.

AgNO3 is a finite reagent, so its 0.0015 mol reacts to make Ag2SO4 0.00075 mol

In 155 ml of solution, then

[Ag2SO4] = 0.004839 M

Then

[Ag +] = 0.009677 M

[SO4 2] = 0.004839 M

0.009677² * 0.004839 = 4.53 * 10 7.

<Ksp, so that there is no rain.

150 ml 0.10 m Na2SO4 = 0.0150 mol Na2SO4.

5.0 ml AgNO3 0.40 M = 0.002 mol AgNO3.

AgNO3 is a finite reagent, so 0.002 mol reacts to form 0.001 mol Ag2SO4.

In 155 ml of solution, then

[Ag2SO4] = 0.01290 M

Then

[Ag +] = 0.02581 M

[SO4 2] = 0.01290 M

0.02581² * 0.01290 = 8.59 * 10 6.

<Ksp, so that there is no rain.

150 ml 0.10 m Na2SO4 = 0.0150 mol Na2SO4.

5.0 ml AgNO3 0.50 M = 0.0025 mol AgNO3.

AgNO3 is a limited reagent, so its 0.0025 mol reacts to form 0.00125 mol of Ag2SO4.

In 155 ml of solution, then

[Ag2SO4] = 0.008065 M

Then

[Ag +] = 0.01613 M

[SO4 2] = 0.008065 M

0.01613² * 0.008065 = 2.1 * 10 5.

> Ksp, to make it rain.

Ksp You are wrong. This is actually 1.2x10 5.

All your answers are incorrect.
