Hi Julie! Thanks for the new post. I see more clearly what goes on. My guess is that KCrO4 (yellow clear solution) would give a yellow PbCrO4 ppt with Pb(NO3)2...

It would be some aromatic aldehyde, like benzaldehyde. Dr. Mukesh Jani julie savitt <jules1527@...> wrote: Greetings, I have been a "lurker" on this...
Not likely. Any reagent which forms a bright yellow precipitate with Pb(NO3)2 would have to have a chromophore of its own, which rules out ordinary simple...
Dear Friends: We are none of us doing our chemist friend Julie any good! This is a combinatorial problem of 10 solutions. There is no "benzaldehyde" nor any...
Dear friends, how to increase the viscotity of alcanes C 10-13? I suppose,that aluminium stearate could used,but I red somewhere that exist modern agents...
Dear Boris: Try fume silica. This is silica gel made by burning silicon tetrachloride in oxygen. This should impart good thixotropic properties to your...
If you want to maintain their purity, a much more preferable method is to simply cool them down to temperatures at which they have the desired viscosities....
Dear Friends, when indole reacts with sodium bisulfie it is making Indoline-2- sulfonate, sodium salt. And the product acetylated with acetic anhydride it is...
As per my knowledge and experience, we have used sodium pyrophosphate about 0.1%. But the suitabiity must be checked for the perticular alkane. Thanks Mukesh...
Hello all, I was wondering if anybody has had a chance to glance at my data that I put in the files section of thechemistrycluster. Thanks for the suggestion...
The "solution that forms navy blue precipitates", at least with Fe, but does not contain Cu, is quite probably a cyanide or ferrocyanide. As I pointed out in a...
Hi Guys, Salinity was defined, in 1902, as the total amount of solid material (g) contained in one kg of seawater when all halides had been replaced by the...
Indole (C7H8N, a secondary amine, with the N in a 5-membered ring with a double C=C bond and fused to a benzene ring to which the N is bonded) has a slight...
Pardon R.: First of all, I do not know. Second, besides getting back to 1902, I would say that the gram equivalent weights of Br and I would have to be...

Hey Julie! JohnWW of New Zealand is undoubtedly correct that one of your navy blue precipitates is Prussian blue--a ferric ferrocyanide. JohnWW suggests that...
Hi Julie! Thanks for telling us your guesses. It is unlikely that you would have both FeCl3 and Fe(NO3)3 as #3 and #9. Unless, as you suggest, your teacher has...
Dear Mr. John, Thanks you very much for your suggestion. IR spectra is very good identification, but the problem is there excess sodium bisulfite is used. So...
Dear friend, All halides are converted in to equivalent chloride because chlorine can replace bromine and iodine. When you pass chlorine gas into HBr or HI ...
Dear Mukesh, Could you complete your tought, please. What do you mean when you say, it is happening? Do they use to pass chlorine gas in seawater samples? ...

Hi everybody, Actually there was a typo on the list. I should have included both K3Fe(CN)6 and K4Fe(CN)6. I am going to select K4Fe(CN)6 as the identity of...
Where did you get that definition from? A much better definition, in my opinion, would be the total moles of dissolved substances per liter, especially because...
