Calculate the molar solubility of lead thiocyanate in pure water. The molar solubility is the maximum amount of lead thiocyanate
OLga [1]

Answer:

Molar solubility(S)=1.71\times10^{-2} mole/litre

Explanation:

Assume Ksp of Pb(SCN)_{2}=2\times10^{-5}( it is general value ,i took it because not given in question)

molar solubilty means how much maximum mole of lead thiocynate is dissolved in one litre of solvent.

Ksp=solubility product;

Pb(SCN)_2= Pb^{2+}  +2SCN^-

Lets molar solubilty of Pb(SCN)_2 is S then

[Pb^{+2}]=S;

[SCN^{-1} ]=2S;

Ksp =S\times(2S)^{2} =2\times10^{-5}

4S^{3}=2\times10^{-5}

S=1.71\times10^{-2} mole/litre
