Gallium is produced by the electrolysis of a solution obtained by dissolving gallium oxide in concentrated naoh(aq). calculate the amount of ga(s) that can be deposited from a ga(iii) solution by a current of 0.490 a that flows for 50.0 min.

The mass of gallium produced by the electrolysis is 0.0354 grams.

Explanation:

The equation for the deposition of Ga(s) from Ga(III) solution follows:

where,

C = charge

I = current = 0.490 A

t = time required (in seconds) =    (Conversion factor: 1 min = 60 s)

Putting values in above equation, we get:

where,

C = charge = 147 C

F = Faradays constant = 96500

where,

n = number of electrons transferred = 3

Putting values in above equation, we get:

Moles of Gallium =

Molar mass of Gallium = 69.72 g/mol

Putting values in above equation, we get:

Hence, the mass of gallium produced by the electrolysis is 0.0354 grams.
