Question

Given;

$E_{C{u}^{2+}|Cu}^{\ominus }=0.34V,E_{Z{n}^{2+}|Zn}^{\ominus }=-0.76V$,
$E_{A{g}^{\oplus }|Ag}^{\ominus }=0.80V$

Assertion: Copper sulphate solution can be stored in silver vessel.

Reason: $E_{cell}^{\ominus }$ is positive.

• A. Both Assertion and Reason are true and Reason is the correct explanation of Assertion
• B. Both Assertion and Reason are true but Reason is not the correct explanation of Assertion
  
• C. Assertion is true but Reason is false
• D. Assertion is false but Reason is true
• E. Both Assertion and Reason are false
  

Answer 1

The correct option is A Both Assertion and Reason are true and Reason is the correct explanation of Assertion

As in Q. 3 above.Cell representation would be:
$\therefore E_{cell}^{\ominus }=(E_{red}^{\ominus }{)}_c-(E_{red}^{\ominus }{)}_a$
= 0.34 - (- 0.80) = 1.14 V
Since $E_{cell}^{\ominus }$ is +ve, so $CuS{O}_4$ solution can be stored in silver vessel.
