  • sorry for the principal species I have given the molarity in the initial solution. However the question is for the resulting solution after reaction.The answers are:

  • for HCl, it will be : H+ and Cl-. H+ molarity will be 0M and for Cl- = (0.0072 mol)/(0.06L)=0.12M

  • for NH4OH: principal species are NH4+ and OH-. their molarities in resulting solution will be OH- = 0M. and NH4+ = (0.0072 mol)/(0.06L)=0.12M

  • moles of HCl =moles of NH4Cl = molarity x volume = 0.030L x 0.240M= 0.0072 mol
