lead dioxide उदाहरण वाक्य

In organic synthesis, lead dioxide anodes were applied for the production of glyoxylic acid from oxalic acid in a sulfuric acid electrolyte.
For instance, a typical 12V lead acid battery has six galvanic cells connected in in series with the anodes composed of lead and cathodes composed of lead dioxide.
The issues with lead white in frescoes are that the large quantities can be highly toxic and, as it oxidizes, it turns a brownish color of lead dioxide.
This is a process in which lead sulfate forms on the plates, and during charge is converted to lead dioxide ( positive plate ) and pure lead ( negative plate ).
The Dayton Project developed techniques for extracting polonium-210 from the lead dioxide ore in which it occurs naturally, and from bismuth targets that had been bombarded by neutrons in a nuclear reactor.

The cells initially had low capacity, so a slow process of " forming " was required to corrode the lead foils, creating lead dioxide on the plates and roughening them to increase surface area.
Permanganate salts can also be generated by treating a solution of Mn 2 + ions with strong oxidants such as lead dioxide ( PbO 2 ), sodium bismuthate ( NaBiO 3 ), or peroxydisulphate.
If the charging current is too great, some of it will be wasted decomposing water into hydrogen and oxygen, in addition to the intended conversion of lead sulphate and water into lead dioxide, lead, and sulphuric acid which reverses the discharge process.
These conclusions were based on the property shown by tannin of forming additive products with water, alcohol, and ether, ( which is stable even in vacuum ) and also on the loss of carbon dioxide and water with formation of hexahydroxybenzophenone, when tannin is heated in aqueous solution with lead dioxide ( the amount of carbon dioxide liberated was estimated ).
