Question

H2 cannot be displaced by : (A)  Li+  (B)  Sr2+  (C)  Al3+  (D)  Ag+

Tardigrade Admin · Accepted Answer

The elements which are below H 2 in electrochemical series, cannot displace H 2, ∵ Out of Li +, Sr 2+, Al 3+, and Ag +, Ag + is below H 2 in electrochemical series. ∴ Ag + cannot displace H 2

Q. $H_{2}$ cannot be displaced by :

$L i^{+}$

$S r^{2 +}$

$A l^{3 +}$

$A g^{+}$

The elements which are below $H_{2}$ in electrochemical series, cannot displace $H_{2}$ ,

$∵$ Out of $L i^{+}, S r^{2 +}, A l^{3 +}$ , and $A g^{+}, A g^{+}$ is below $H_{2}$ in electrochemical series.

$∴ A g^{+}$ cannot displace $H_{2}$
