Sn2 and N (starting concentration 10 mol/L) should be separated byfractionated precipitation using H₂S. Does a pH range exist allowing tocompletely precipitate one metal (i.e. the remaining concentration of theprecipitated ion has to be 10 mol/L or less) whereas the other stays insolution at its initial concentration? Please calculate this pH range whereby pHvalues below zero are set to zero! Please illustrate the situation graphically byplotting pH versus in solution/precipitating/fully precipitated for the two ions (9)Solubility product (SnS): 10; (NIS): 1021;Acid constant (H2S): 10-20,r/Concentration of H2S in water: 0.1 mol/L

These points illustrate the pH range where one metal ion can be completely precipitated while the…

In a titration, the equivalence point is the moment at which the number of moles of H+ from the acid that has been added is equal to the number of moles of OH- from the base that has been added. Remember that in a molecule like H2SO4, there are 2 moles of H+ per mole of H2SO4. 16.31 mL of 0.100M H2SO4(aq) is placed in a beaker. After 17.98 mL of NaOH is added to the beaker, the equivalence point is reached. What is the concentration (M) of the NaOH solution?
