A) 6.4 g
B) 2.3 g
C) 12.8g
D) 3.2g
Correct Answer: D
Solution :
Number of equivalents of silver formed = Number of equivalents of copper formed. In \[AgN{{O}_{3}},\text{ }Ag\]is in +1 oxidation state. In \[CuS{{O}_{4}},Cu\]is in +2 oxidation state. Equivalent weight of \[Ag=\frac{108}{1}=108\] Equivalent weight of \[Cu=\frac{63.6}{2}=31.8\] \[\frac{{{M}_{1}}}{{{M}_{2}}}=\frac{{{E}_{1}}}{{{E}_{2}}};\frac{10.79}{{{M}_{Cu}}}=\frac{108}{31.8}\] \[{{M}_{Cu}}=\frac{10.79\times 31.8}{108}=3.2\,g\]You need to login to perform this action.
