sorry de the previus article wasn´t complete

well if you read the previus article you will see how obtain Na2PbO2 isnt it?

well now you take the Na2PbO2 and make this:

Na2PbO2 + 2NaNO3 + 4NaHSO4 --->Pb

(NO3)2 + 2H2o

it seems too hard just to obtain a nitrate but in some countries as spain isnt easy obtain some chemical products this for example
you can get it but you have to answer to many questions

Can you get H2SO4? If you can you can react it with your NaNO3 and distill to make HNO3. React your HNO3 with lead and evaporate till dryness and you have pure crystalline Lead Nitrate.

thanks but..

will HNO3 attack lead? i´ve heard that lead is quite acid resistant and the acid just will attack a small quantity of the lead will it be so? thanks a lot for your help im trying to learn to formulate in english but.. if i have some mistake please let me know thanks again

Don't make the mistake trying to attack somewhat less reactive metals with highly concentrated acids, because these cause passivation which stops further attacks.
A slightly diluted acid which is fully ionized is the most effective.



One shouldn't accept or resort to the mutilation of science to appease the mentally impaired.

In this case concentrated HNO3 works better.
The reaction of HNO3 with lead to yield lead nitrate is always accompanied by the evolution of nitrogen dioxide, so do this outside ;)

I forgot to mention that it does need a bit of heating.
