Engineers attach a sacrificial anode to the copper pipe. to use impressed current cathodic protection, they must attach a battery between the cathode and anode. which material should the positive side of the battery be attached to? explain how you know.

SEE EXPLANATION

Explanation:

Cathodic protection means the attachment of a sacrificial anode which corrodes instead of the protected metals. This is common in iron and zinc system.

The sacrificial anode makes use of a metal more active than the base metal to “sacrifice” ions. These “sacrificial anodes” (usually alloys such as magnesium, aluminum, or zinc) have a much stronger electrochemical potential.

This is because current now flows in the opposite direction due to the DC.

The sacrificial anode may be positive

The protected metal may be the negative electrode

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.
