Question

AgCl is soluble or insoluble? how do I identify this? ( by using table: solubility rules of salts in water)

Answer 1

haha you answered this yourself, use a table of solubilities

Answer 2

how do i use table?

Answer 3

1. Salts containing Group I elements are soluble (Li+, Na+, K+, Cs+, Rb+). Exceptions to this rule are rare. Salts containing the ammonium ion (NH4+) are also soluble.
2. Salts containing nitrate ion (NO3-) are generally soluble.
NO3^- All nitrates are soluble.

3. Salts containing Cl-, Br-, I- are generally soluble. Important exceptions to this rule are halide salts of Ag+, Pb2+, and (Hg2)2+. Thus, AgCl, PbBr2, and Hg2Cl2 are all insoluble.
Cl- All chlorides are soluble except AgCl, Hg2Cl2, and PbCl2.

4. Most silver salts are insoluble. AgNO3 and Ag(C2H3O2) are common soluble salts of silver; virtually anything else is insoluble.
5. Most sulfate salts are soluble. Important exceptions to this rule include BaSO4, PbSO4, Ag2SO4 and SrSO4 .
SO4^2- Most sulfates are soluble. Exceptions include BaSO4, PbSO4, and SrSO4.

6. Most hydroxide salts are only slightly soluble. Hydroxide salts of Group I elements are soluble. Hydroxide salts of Group II elements (Ca, Sr, and Ba) are slightly soluble. Hydroxide salts of transition metals and Al3+ are insoluble. Thus, Fe(OH)3, Al(OH)3, Co(OH)2 are not soluble.
OH^- All hydroxides are insoluble except those of the Group 1 elements, Ba(OH)2, and Sr(OH)2.
Ca(OH)2 is slightly soluble.

7. Most sulfides of transition metals are highly insoluble. Thus, CdS, FeS, ZnS, Ag2S are all insoluble. Arsenic, antimony, bismuth, and lead sulfides are also insoluble.
S^2- All sulfides are insoluble except those of the Group 1 and Group 2 elements and NH4+.
8. Carbonates are frequently insoluble. Group II carbonates (Ca, Sr, and Ba) are insoluble. Some other insoluble carbonates include FeCO3 and PbCO3.
CO3^2- All carbonates are insoluble except NH4+ and those of the Group 1 elements.
9. Chromates are frequently insoluble. Examples: PbCrO4, BaCrO4
10. Phosphates are frequently insoluble. Examples: Ca3(PO4)2, Ag3PO4
11. Fluorides are frequently insoluble. Examples: BaF2, MgF2 PbF2.

Answer 4

look at 3.

Answer 5

okay so AgCl is insoluble, althought cl is soluble?

Answer 6

soluble + insoluble= insoluble?

Answer 7

yep when in contact with each other in solution they will form a precipitate

Answer 8

ok, so Ag2Co3 is soluble since Ag= insoluble Co3= insoluble ( carbonate are insoluble )

Answer 9

i mean "in"

Answer 10

haha yep, thats right. the ions themselves are soluble but when they form a compounds they become insoluble

Answer 11

Mg(No3)2 is also soluble...?

Answer 12

yes

Answer 13

it seems to me that the most of them are soluble

Answer 14

keep in mind that all compounds can be insoluble at really high concentrations though. a better measure of a compounds solubility is it's Ksp

Answer 15

*in

Answer 16

Ok thank you very much.

Answer 17

are you a chem major student?

Answer 18

no problem. I'm specializing in molecular biology and I'm doing a minor in chem possibly a major since they overlap greatly

Answer 19

Oh i see. that is great. when you are online often?

Answer 20

i'm online a lot since i bring my laptop to class, right now I'm actually studying for an organic chem test i have tmrw

Answer 21

so you could help me if i have questions sometimes again ? good luck with your organic chem test tomorrow!

Answer 22

for sure, if I'm on ill typically answer relatively fast

Answer 23

given that i know the answer :P

Answer 24

Thank you!! I really want to do well on the next chem exam.

Answer 25

(y) i hope you do. also i don't know if I've told you but the khan academy website has tons of videos on chemistry and math and biology, you should check it out

Answer 26

anyway I'm going to bed dude, have a good one!

Answer 27

again thank you!
