A cylindrical steel tank is coated with a thick layer of zinc on the inside. The tank is 34 cm in diameter, 61 cm high and filled to the 27 cm level with aerated water. If the corrosion current is 5.9x10^-5 A/cm², how much zinc in grams per day is being corrode

PLEASE DOUBLE CHECK THE ANSWER THIS IS MY FINAL ATTEMPT< THANKS A LOT

Solutions

Expert Solution

Given information in the problem:

Diameter of tank (DT) = 34 cm

Height of tank (HT) = 61 cm

Filled height of tank with aerated water (HF) = 27 cm

Corrosion current density,

---------------------------------------------------------------------------------------------------------------------

Tank surface area in contact with aerated water (AT) = Bottom surface area + Curved surface area with filled tank height

---------------------------------------------------------------------------------------------------------------------

Corrosion rate,

W = Total amount of Zinc corrode (gram)

t = the total time of corrosion (s)

I = Corrosion current (A)

M = Molecular weight (gram/mole)

n = Oxidation number for Zinc

F = Faraday constant (A.s/mole)

---------------------------------------------------------------------------------------------------------------------

So, 6.5464 gram Zinc being corrodes per day.

Modern pennies are composed of zinc coated with copper. A student determines the mass of a penny to be 2.480 g and then makes several scratches in the copper coating (to expose the underlying zinc). The student puts the scratched penny in hydrochloric acid, where the following reaction occurs between the zinc and the HCl (the copper remains undissolved): Zn(s)+2HCl(aq)→H2(g)+ZnCl2(aq) The student collects the hydrogen produced over water at 25 ∘C. The collected gas occupies a volume of 0.903 L...
