A lead salts is dissolved in `HC1` which si `95%` ionised. It is found to have `0.1M Pb^(2+)` and `0.28M H^(o+)` ions. The solution is satured with `H_(2)S(g)`. Calculate the amount of `Pb^(2+)` ions that remains unprecipitated.
`K_(sp)` of `PbS = 4 xx 10^(-29)`,
`K_(sp)` of `H_(2)S = 1.1 xx 10^(-22)`
