Primarygun Posted February 17, 2006 Share Posted February 17, 2006 Is lead(II) chloride soluble in NaOH(aq)? Link to comment Share on other sites More sharing options...
Tetrahedrite Posted February 19, 2006 Share Posted February 19, 2006 I don't think so, all common salts of lead are insoluble (except nitrate and acetate). Link to comment Share on other sites More sharing options...
JustStuit Posted February 20, 2006 Share Posted February 20, 2006 Yep, it is an insoluable salt Link to comment Share on other sites More sharing options...
woelen Posted February 20, 2006 Share Posted February 20, 2006 It is soluble in a concentrated NaOH solution. This is due to formation of so-called plumbate (II) anions. Lead (II) is amphoteric. It can react as a base, but also as an acid. Many metal-ions are amphoteric (other examples are Al(3+), Cr(3+), Sb(3+), Be(2+), and even Cu(2+) to a little extent). PbCl2 + 2OH(-) --> Pb(OH)2 + 2Cl(-) Pb(OH)2 + 2OH(-) --> PbO2(2-) + 2H2O The solution has to be fairly strongly alkaline before Pb(OH)2 dissolves. I do not know how much Pb(OH)2 dissolves, but I think a fairly large amount. Link to comment Share on other sites More sharing options...
