By titration, it is found that 91.9 mL of 0.150 M NaOH(aq) is needed to neutralize 25,0 mL of HCl(aq). Calculate the concentration of the HCl solution. HCl concentration: A solution of NaCl(aq) is added slowly to a solution of lead nitrate, Pb(NO3)2(aq), until no further precipitation occurs. The precipitate is collected by filtration, dried, and weighed. A total of 19.42 g PbCl(s) is obtained from 200.0 mL of the original solution. Calculate the molarity of the Pb(NOx),(aq) solution. concentration:

A solution of 50.0 mL of 0.045 M Ca(NO,), is prepared. What volume (in mL) of 1.90 M NaOH must be added to the calcium nitrate solution to begin to precipitate solid Ca(OH), from the solution? K = 6.5 x 10 Hint: Solid Ca(OH), will begin to precipitate at the point where an equilibrium exists between the solid and aqueous ions. The volume of NaOH required, will be very small so you don't have to consider the dilution of the...
