Lead(II) nitrate is an inorganic compound with the chemical formula Pb(NO3)2. It commonly occurs as a colourless crystal or white powder and, unlike most other lead(II) salts, is soluble in water.
One mole of lead (Pb) contains 6.02 × 1023 atoms and its mass is 207.2 g.

602,000,000,000,000,000,000,000 atoms
To find out the number of atoms: MULTIPLY all the SUBSCRIPTS in the molecule by the COEFFICIENT. (This will give you the number of atoms of each element.)
Precipitation ReactionsThey contain two aqueous reactants, one aqueous product, and one solid product. In this reaction, two soluble products, Pb(NO3)2 and KI, combine to form one soluble product, KNO3, and one insoluble product, PbI2. This is a precipitation reaction, and PbI2 is the precipitate.
Sodium sulfide is water soluble.
Is Lead II nitrate soluble?
A precipitate of lead(II)chloride forms when 150.0 mg of NaCl is dissolved in 0.250 L of 0.12 M lead(II)nitrate. Ksp of PbCl2 is 1.7 x 10-5. A precipitate of lead(II)chloride forms when 150.0 mg of NaCl is dissolved in 0.250 L of 0.12 M lead(II)nitrate.
Is CA no3 2 soluble in water?
This is a precipitation reaction: PbSO 4 is the formed precipitate.
Any dissolved ions that appear in the same form on both sides are spectator ions. Cross out the spectator ions to produce a net reaction. If all reactants and products cross out, then no reaction will occur.
This is a precipitation reaction: PbSO 4 is the formed precipitate.
When you dissolve ammonium chloride crystals in water (H2O), the ammonium chloride compound decomposes into its component ions: NH4+ and Cl-. The dissociation chemical reaction is: NH4Cl(solid) = NH4+(aqueous) + Cl-(aqueous).
The reaction is an example of a metathesis reaction, which involves the exchange of ions between the Pb(NO3)2 and KI. The Pb+2 ends up going after the I- resulting in the formation of PbI2, and the K+ ends up combining with the NO3- forming KNO3. NO3- All nitrates are soluble. (Many acid phosphates are soluble.)
The nitrate ion is a radical with an overall charge of -1. To get the oxidation number of lead add up all the oxidation numbers and equate to zero. Where x= O.N of lead. Therefore the oxidation state of lead is +2.
Molecular formula Pb(NO3)2. Appearance Clear, colorless liquid. Molecular weight 331.20. Odor No odor.
Lead(II) chloride (PbCl2) is an inorganic compound which is a white solid under ambient conditions. It is poorly soluble in water. Lead(II) chloride is one of the most important lead-based reagents.
What is the correct name for Pb no3 2?
Lead(2+) ionPlease visit the Lead element page for information specific to the chemical element of the periodic table. Lead(2+) is a lead cation, a divalent metal cation and a monoatomic dication. It has a role as a cofactor.
Lead is a chemical element with the symbol Pb (from the Latin plumbum) and atomic number 82. Its weak metallic character is illustrated by its amphoteric nature; lead and lead oxides react with acids and bases, and it tends to form covalent bonds.
Cancer Hazard? Lead Nitrate is a PROBABLE CARCINOGEN in humans. There is some evidence that inorganic Lead compounds cause lung, brain, stomach, and kidney cancer in humans and they have been shown to cause kidney cancer in animals.
The compound lead nitrate is a strong electrolyte.
HF is a polar covalent compound. fluorine is most electronegative among all the halogens when it reacts with hydrogen it forms a covalent compound. So due to large difference in electronegative the electron cloud density is pulled my fluorine to form a polarized compound.
Answer. Lead nitrate is produced by reaction of lead(Icolourles oxide with concentrated nitric acid: PbO + 2 HNO3(concentrated) → Pb(NO3)2 + H2O. It may also be obtained evaporation of the solution obtained by reacting metallic lead with dilute nitric acid.
