Other names: Peru saltpeter, Soda niter, Cubic niter. Dithizone is green in color in chloroform and lead-dithizone complex is violet in color, so the resulting color at the end of process is red.Appearance: White powder Colourless crystals.Other names: Lead carbonate, Cerussite, Carbonic acid, lead(2+) salt, Lead(2+) carbonate.Heat both beakers together on a hot plate. Put 100 ml of laboratory water in each beaker. Appearance: White solid, hygroscopic White hygroscopic powder Label one beaker soap and one beaker detergent.Lead iodide (PbI 2) Lead iodide is a yellow precipitate. Lead bromide is too soluble in hot water and alkali hydroxides. But, as products KNO 3 can be formed in the aqueous phase while forming lead bromide precipitate. It can be prepared easily by mixing lead nitrate with potassium bromide (KBr). When solid Pb(NO3)2 is place on one side and solid KI on the other, PbI2 precipitates in. Lead bromide is a white-cream colour precipitate. PbCO 3, PbSO 4 are insoluble white precipitates. Lead ion forms soluble compounds and insoluble compounds in water and some of them have colours. 1 may be used to predict whether a precipitation reaction will occur when solutions of soluble ionic compounds are mixed together.

In qualitative analysis of inorganic chemistry, there are tests to identify Pb 2+ ion from other cations. 1: A precipitate of PbI 2 forms when solutions containing Pb 2+ and I are mixed. show more Sodium carbonate (anhydrous), Na2CO3, Disodium carbonate, Natriumkarbonat, Carbonic acid sodium salt (1:2), Anhydrous sodium carbonate, Carbonic acid, disodium salt, Sodium carbonate, anhydrous, Soda-ash, Natrum carbonicum, Sodium carbonate anhydrous, Sodium salt of carbonic acid, Carbonic acid disodium salt show less A 100mm petri dish containing water is placed on an overhead projector. Lead is an amphoteric metal and its oxides and hydroxides are also amphoteric compounds.
Other names: Soda ash, Washing soda, Soda crystals.Appearance: White colourless crystals White or colourless crystals.show more Plumb dulcis, , Lead (II) nitrate show less 3(aq) Hg (s, black) + HgNH 2 Cl (s, white) + NH 4 +(aq) + Cl-(aq) (7) As this reaction occurs, the solid appears to change color, from white to black or grey which indicates the presence of mercury. Both Lead iodide and Silver iodide has same colour Both Lead iodide and Silver iodide. Other names: Lead nitrate, Plumbous nitrate, Lead dinitrate. Lead iodide is a yellow colour precipitate which is not soluble in water.
