How many grams of PbCO3 will dissolve when exactly 5.0 L of 1.25 M H is added to 6.0 g of PbCO3?
When the equation is PbCO3(s) + 2H(+)(aq) = Pb(2+)(aq) + H2O(l) + CO2(g)
Is this anything more than a stoichiometry problem? I don't think so.
Here is a set of directions for working stoichiometry problems. M x L = moles. Convert moles H^+ to moles Pb^2+ and convert to grams PbCO3.
the solubility of Kl is 50g in 100g of H2O at 20 celcius, if 110g of Kl are added to 220g of H2O, is the soultion saturated or unsaturated?
and what is the %m/m of the solution?
