Solubility of PbSO4 - Chemistry Stack Exchange
WEBMay 15, 2019 · The solubility of $\ce{PbSO4(s)}$ increase with the addition of $\ce{H2SO4}.$ Why? I don't quite understand this. When dissolving $\ce{PbSO4(s)}$ we get the equilibrium equation: $$\ce{PbSO4(s) <=> Pb^2+ + SO4^2-}$$ I know $\ce{H2SO4}$ is a strong acid, that will dissociate completely (or almost completely), …
Redox potential of a lead–acid battery - Chemistry Stack Exchange
WEBJan 17, 2018 · But for the first reaction I think that the underlying redox pair has to be PbX2+ +2eX− Pb P b X 2 + + 2 e X − P b. This redox pair has standard potential of −0.1263 V − 0.1263 V. This result in a voltage of ≈1.55 V ≈ 1.55 V. But Wikipedia and a book of mine tell the the voltage of this battery type is 2.04 V 2.04 V.

WEBApr 11, 2020 · $\ce{ .HO2 + PbSO4 -> PbO2 (s) + HSO4- }$ or, just oxidize any liberated Pb. I would even suggest you try this process out by creating a test solution (with at least added Lead) and heat in H2SO4 to form a heavy metal impurity and then apply the UV light/TiO2 (and also added oxygen) therapy.
What is the name of the compound PbSO4? - Answers
WEBMay 22, 2024 · The molecular weight of PbSO4 is 303.3 grams per mole. A sample weight of 158.1 grams corresponds to .5213 moles of PbSO4. Is pbso4 ionic? Yes, PbSO4 (lead(II) sulfate) is an ionic compound. It is ...
electrochemistry - Cell notation for the lead-acid battery
WEBThe $\ce{PbSO4}$ formed at the anode is in solid state. Hence, writing it as $\ce{Pb^2+(s)}$ is incorrect, as it is not dissociated into the ions $\ce{Pb^2+}$ and $\ce{SO4^2-}$ . With all these corrections, your final, correct cell representation should be:
What is the oxidation number of PbSO4? - Answers
WEBPb, lead, +2; S, sulfur, +6; O, oxygen, -2. The oxidation number of Pb in PbSO4 is +2. This is because the oxidation number of oxygen is typically -2, and the overall charge of the sulfate ion ...

WEBAug 6, 2021 · In the original lead electrode, equation ($1$) is reversed, and $\ce{PbSO4}$ is reduced to $\ce{Pb}$. The electrode is not an anode any more. It is a cathode. But the sign of the electrode is maintained negative, as the lead ion $\ce{Pb^{2+}}$ needs electrons to be regenerated into $\ce{Pb}$. So the minus sign (-) can be printed or engraved on ...

What are the oxidizing and reducing agents in the reaction?
WEBMar 15, 2016 · You are correct, the Pb(s) is oxidized, which makes it the reducing agent. However, there is no change in the oxidation state of the H or the SO4−, so it is not the oxidizing agent. Rather the PbO2(s) is the oxidizing agent, as the Pb goes from +4 in the PbO2(s) to +2 in the PbSO4(s).
