Question

An aqueous solution of sodium acetate is subjected to Kolbe's electrolysis to prepare ethane.If a current of 5A is passed for 1930 sec then total volume of all gases collected at STP is?​

Answer 1

Answer:

An aqueous solution of sodium acetate is subjected to Kolbe's electrolysis to prepare ethane. If a current of 5 A is passed for 1930 sec, then total volume of all gases collected at STP is rapy 2.24 L GRY 4.48 L (3) 5.6 L (4) 11.2 L.

Answer 2

Answer:

$2CH_{3}COO^{-}Na^{+} + 2H_{2}O$ → $CH_{3} -CH_{4} + 2CO_{2} + H_{2} + 2NaO_{4}$

$q = it$

$i = 5A\\t = 1930 sec$

$q = 5$ × $1930$ $= 9650$$c$

$96500c$ ⇒ $1 mole$ ⇒$22.4l$

Here $n-factor = 2$

Now, as we know,  $96500c = 44.8l$ ----------------- {1}

dividing equation {1} by 10, we get that

$9650c = 4.48l$

Hence our answer is $4.48l$

When aqueous sodium acetate solution is electrolyzed, acetate ions form. With the evolution of carbon dioxide, two acetate ions interact at the anode to generate ethane.

Kolbe's electrolysis method is a generic method for producing substituted hydrocarbons from substituted carboxylic acids using an electric discharge mechanism that releases carbon dioxide gas. It is one of the most common processes for producing alkanes and substituted hydrocarbons.
