Expert Solution

NiCl2(aq)+2NaOH(aq)→Ni(OH)2(s)+2NaCl(aq)

1 mole    2 moles

NaOH                                             NiCl2

M1 = 0.2M                                    M2 = 0.37M

V1   =                                              V2 = 34ml

n1 = 2                                             n2= 1

              M1V1/n1     =       M2V2/n2

                  V1             = M2V2n1/M1n2

                                     = 0.37*34*2/0.2*1    = 125.8ml   >>>>>.answer
