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:
