What is the chemistry of recharging the lead battery?
Dr M KanagasabapathyAsst. Professor in ChemistryRajus college, Affiliated to M K UniversityRajapalayam (TN) India------------------------------------------------------------------------------------------------------Lead acid battery contains the following1. Lead PB2. Lead oxide PbO3. Sulfuric acid H2SO4During discharging Pb Oxidizes to Pb 2+ and PbO2 reduces to Pb2+ from Pb 4+PbO2 + Pb + H2SO4 = 2 PbSO4 + H2O (~ 2.0 V per cell)During charging the reverse reaction takes placePb2+ reduces to lead at cathode and another molecule of Pb2+ oxidizes to PB4+ or PbO2 by reacting with distilled water.2 Pb(2+) + H2O2 = Pb + PbO2 (> 2.0 V per cell)The important thing is the voltage for recharging should be slightly higher than the discharging voltage.During discharging the battery functions as electrochemical cell.And during charging it becomes an electrolytic cell.By,Dr M KanagasabapathyAsst.

How many electrons does an atom of lead have if it is positively charged?
Lead forms the Pb2+ ion, as lead has an atomic number of 82, the Pb2+ ion has 80 electrons in total
What is the chemical formula for lead tetracarbonate?
Formula: Pb2(CO3)4
Why is lead chloride a powerful oxidizing agent?
The oxidation state 4+ is not stable in PbCl4; the reaction is:Pb4+ + 2 e---------Pb2+
What changes occur when h2so4 is mixed with water to test for pb2?
Lead (II) sulfate precipitate forms by:Pb2+(aq) + SO42-(aq) + [2H+]tribune --> [PbSO4]solid + [2H+]tribune
Which is good oxidising agent PbO2 or PbO?
PbO2....Pb has a 4+ charge and therefore can be reduced to Pb2+ in PbO. Since it can be reduced it is an oxidizing agent.

What is the correct formula formed from lead(Pb) plus 4 and Oxygen(O)-2?
The chemical formula of lead tetroxide is Pb3O4.
What is the symbol for lead ion?
Pb2+
What is the chemical formula for lead salt?
Pb2+
What is the formula for plumbous ion?
Formula: Pb2+
PbBr2 soluble in water?
It is very slightly soluble in water.In a saturated solution:[Pb2+] = 1.2x10-2 mol/L[Br-] = 2.4x10-2 mol/Lbecause [Pb2+]*[Br-]2 = Ks = 6.3*10-6 and [Br-] = 2*[Pb2+]
What is mean by PBM in mass transfer?
It is the log mean value of the inert B in counterdiffusion usually used to find a flux. P = pA1 + pB1 = pA2 + pB2 thus, pB1 = P - pA1, and pB2 = P - pA2, so: pBM = [pB2 - pB1]/ln(pB2/pB1) = [pA1 - pA2]/ln[(P-pA2)/(P-pA1)] happy engineering :)
What is the formula of lead 4 oxide?
(Pb2)O
What is the metallic ion in lead II sulfate?

What is the symbol for lead II hydroxide?
Pb2(oh)
How many electrons does an atom of lead have if it is positively charged?
