Lead in drinking water (1 Viewer)

[annabananna88]

Hey, just a quick question
Ive been looking for an equation of a lead compound reacting with water and im going no where... so if anyone has some ides that would be awesome
Thanks

Its for the monitoring ion section


Edit: i actually found some last nite....
if anyone else needs em (was doing an assignment its

PbCl2 which is slightly soluble, but dissolves in excess Chloride ions
PbCl2(s) + 2Cl-(aq) <==> [PbCl4]2-(aq)
And Pb(OH)2 which is also slightly soluble, yet dissolves in excess hydroxide:
Pb(OH)2(s) + 2OH-(aq) <==> [Pb(OH)4]2-(aq)

they kinda work

i dont get what you need this for... also reacting with water ? what do you mean ?

(ionising maybe ? PbCl2 + H2O(l) ---> Pb^2+ + 2Cl^- + H2O(l))

All i am doing for lead is remembering the wet test for it

Pb^2+ ions (any lead salt) + 2I^- ions ---> PbI2 (s) Bright yellow precipitate (google picture it - it's gunky crap that's horrible to clean off of test tubes

If i have missed something please do let me know cheers

hmm

i thought the biggest problem is that it isnt really soluble..

hence stay in metal form or solid form, and is toxic??
