A 4.50g mixture of lead nitrate and copper nitrate was dissolved in 100ml of water. to this solution was added sodium sulphate solution, resulting in the precipitation of a white solid. for complete precipitation, exactly 18;55ml of 0.24mol/l sodium sulphate solution was used

write equation for this precipitation reaction

Sorry @RANE  I haven't done Chemistry in 6 years, I can't help you with this! Sorryyyy

rane · Answer

no problem

Sorry yar i can't help you with this it's too difficult for me i am not that good in chemistry and i haven't done it for a long time

rane · Answer

np :)

kc_kennylau · Answer

but i think that the precipitate is sodium nitrate since it got no colour

rane · Answer

i have to write an equation first then ionic equation in order to answer other q' s reeled to that

anonymous · Answer

Pb(NO3)2+Cu(NO3)2---->PbSO4+2NaNO3
and i dont think u have to read water in it ...

rane · Answer

y not ?

anonymous · Answer

caz its not important ...

rane · Answer

howcome? we have always added water in all equations

anonymous · Answer

u can add it if u want to ...

rane · Answer

yh i tried but then i couldn't figure out the products

anonymous · Answer

same here ...

anonymous · Answer

and my brother was like ....u dont need to do the water...

rane · Answer

yh but u could've asked him y not ? w8 i think i have to call my brother

anonymous · Answer

lol :D ..u never leave ur brother in peace .. :)

rane · Answer

excuseme

anonymous · Answer

wht ?? ..i was just kidding..... :)

rane · Answer

yh anyways i got it

rane · Answer

u need to react lead nitrate and copper nitrate separately with water. which ever would produce the white precipitate is the reaction that u need to write

rane · Answer

did u get it ?

anonymous · Answer

ooh ..okk ...yes i got it :)

rane · Answer

ilham u were right. your equation is right u don't react it water

anonymous · Answer

yh ...caz my brother told its right so yh ... :)

rane · Answer

yh my brother told me that as well

rane · Answer

thanlx to our brothers otherwise, again the same person could've been answering the q's on monday
