Answer to Question #160634 in General Chemistry for Dexther Villanueva

Question

Which of the following represents the equivalent weight of KHC2O4•H2C2O4•2H2O as an acid and as reducing agent, respectively?

A. 84.73/63.55

B. none of the given answers

C. 63.55/85.03

D. 127.55/127.55

E. 63.55/85.03

Answer 1

As we know,

$Equivalent weight(E) = M/valency factor$

Valency factor for acid is number of ionizable H+ ions. And for reducing agent is change in oxidation number.

So, for as an acid

E =127.55

As an reducing agent

E = 127.55/2 = 63.55

So, [B] is correct.
