44.2 mL of aqueous 0.255 M Pb(NO3)2 is mixed with 31.6 mL of 0.415 M NaCl. The equation for the precipitate reaction is: Pb(NO3)2 (aq) + 2 NaCl (aq) --> PbCl2 (s) + 2 NaNO3 (aq) The concentration of NO3- ion in the reaction solution is _____ M.
A 1.04 g sample of KBr is dissolved in water to give 155 mL of solution. This solution is then added to 165 mL of 0.015 M aqueous Pb(NO3)2, in an attempt to remove the toxic lead(II) ions from the solution via precipitation as insoluble PbBr2(s). The precipitation reaction that occurs is: PB2+(aq) + 2Br(aq) --> PbBr2(s) What is the maximum mass of product that could be isolated by filtration after the reaction occurs?
