Please explain as simply as possible as well

Solutions

Expert Solution

fluorine –answer

Fluorine:

it can be prepared by the electrolysis of liquid HF

More positive (less negative) the standard reduction potential, greater the oxidizing power.

, F- has greater oxidizing power than water.

Hence

water will be oxidized to  O2at anode

===================================================

silver and copper

metal by electrolysis of an aqueous solution of its salts .

as silver and copper have higher reduction potential than water

===================================================

calcium-------- metal that cannot be obtained by electrolysis of an aqueous solution of its salts is Ca.

===================================================

Potassium--------- will react with water. And forms hydroxide solutions,

Electrolysis of hydroxide solutions, any metal released at the cathode will immediately react with the water

=============================================
