I. $\mathrm{Sn}-\mathrm{HCl}$
II. $\mathrm{Sn}-\mathrm{NH}_{4} \mathrm{OH}$
III. $\mathrm{Fe}-\mathrm{HCl}$
IV.Zn - HCl
V. $\mathrm{H}_{2}-\mathrm{Pd}$
VI. $\mathrm{H}_{2}$ - Raney Nickel
Solution:
(i) $\mathrm{Sn}+\mathrm{HCl}$
(ii) $\mathrm{Fe}+\mathrm{HCl}$
(iii) $\mathrm{Zn}+\mathrm{HCl}$
(iv) $\mathrm{H}_{2}-\mathrm{Pd}$
(v) $\mathrm{H}_{2}$ (Raney $\mathrm{Ni}$ )
