Lead(II) nitrate is an inorganic compound with the chemical formula Pb(NO 3) 2. ... Solutions and crystals of lead(II) nitrate are formed in the processing of lead ...
Golden rain demonstration is made by combining two colorless solutions, potassium iodide solution and Lead(II) nitrate solution at room temperature to form yellow precipitate. During the chemical reaction, golden particles gently drop from the top of Erlenmeyer flask to the bottom, similar to watching the rain through a window.
Tarnished lead (left) and shiny lead (right) Compounds of lead exist with lead in two main oxidation states: +2 and +4. The former is more common. Inorganic lead(IV) compounds are typically strong oxidants or exist only in highly acidic solutions. [1] Red α-PbO and yellow β-PbO The mixed valence oxide Pb 3 O 4 Black PbO 2 which is a strong ...
Lead(II) azide is prepared by the reaction of sodium azide and lead(II) nitrate in aqueous solution. [6] [5] Lead(II) acetate can also be used. [7] [8] Thickeners such as dextrin or polyvinyl alcohol are often added to the solution to stabilize the precipitated product. In fact, it is normally shipped in a dextrinated solution that lowers its ...
One way to produce lead(II) iodate involves the reaction of lead nitrate with double moles of potassium iodate. Lead iodate can be precipitated precisely by simultaneous dropwise addition of equivalent solutions of lead nitrate and potassium iodate with water as a solvent at around 60 °C. [1] Pb(NO 3) 2 (aq) + KIO 3 (aq) → KNO 3 (aq) + Pb(IO ...
The formation of a precipitate can be caused by a chemical reaction. When a barium chloride solution reacts with sulphuric acid, a white precipitate of barium sulphate is formed. When a potassium iodide solution reacts with a lead(II) nitrate solution, a yellow precipitate of lead(II) iodide is formed.

It is thought to be more permanent; but time only can prove its pretension to so essential a quality. It is prepared by precipitating a solution of acetate or nitrate of lead, with potassium iodide: the nitrate produces a more brilliant yellow color." [16] However, due to the toxicity and instability of the compound it is no longer used as such ...
