All nitrates are soluble .ur right... m getting da same
tho m not sure abt 1 or 2..
Just found this note:
yes! dese r da set of rules i learnt tooJust found this note:
All nitrates are soluble.
All group one salts are soluble and all NH4+ salts are also soluble
All chlorides are soluble except for lead, silver and mercury
All sulphates are soluble other than lead, barium and calcium
No carbonates are soluble other than the group one and ammonium
I think that covers all of them. Right?
two more :Just found this note:

6) Group 1 compounds. True
6) Group 1 compounds. True
7) All hydroxides: An additional detail is that their solubility decreases as you go down the group! (group 2 for now)
So you can't say that it's just calcium and barium. Whereas beryllium hydroxide is insoluble... Radium and barium hydroxides are the most soluble
8) All group one and two sulphides are soluble. Rest are mostly insoluble!
IN CONCLUSION:
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.
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.
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 .
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.
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.
8. Carbonates are frequently insoluble. Group II carbonates (Ca, Sr, and Ba) are insoluble. Some other insoluble carbonates include FeCO3 and PbCO3.
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.
Really? Our teacher taught it anyways.
Ab ye Chromates kya cheez hai?
we're in O level ! At this stage 7 are required , and even that is going to an extent .
It's CrO with an oxidation state of 2- and properties not exactly part of the syllabus

i didn't , actually. my sight fell on the one word so i askedReally? Our teacher taught it anyways.
But if you don't need it don't read it
dis aint chlorophyllwhen it is boiled in tube of ethanol in a water bath!
when you label a bottle of water as ''Universal Indicator''
I "THINK" when it's in liquid state and you pass chlorine through it. In paper form... there is no way
thanks for ur helpI "THINK" when it's in liquid state and you pass chlorine through it. In paper form... there is no way
No problem. Although you will have to confirm it from others as i am not surethanks for ur help
People confirm this !No problem. Although you will have to confirm it from others as i am not sure
