What is oxidation in an electrolytic cell with aluminum and gold electrodes?
the gold metal
What is oxidation in a galvanic cell with aluminum and gold electrodes?
The aluminum metals
What is oxidized in an electolytic cell with aluminum and gold electrodes?
In an electrolytic cell with aluminum and gold electrodes, aluminum would be oxidized at the anode. This is because aluminum has a higher tendency to lose electrons compared to gold, making it more likely to undergo oxidation.
Why is gold found as gold metal but aluminium is found as aluminium oxide?
Gold is a very unreactive element, so it occurs as gold metal in nature. However, aluminum is more reactive, and so it occurs in aluminum ore (aluminum oxide) in nature, not as aluminum metal.
What will be true if gold and aluminum are used to form an electrochemical cell?
A.) Solid gold will form. B.) Aluminum will be oxidized
Is gold less dense than aluminium?
No, gold is much more dense that aluminum.
How much would it be to convert yellow gold to white gold?
necklace yellow gold can convert to a white gold?
What effect does hydrofluoric acid have on gold?
Hydrogen Fluoride (HF) will react with the surface of the aluminum and convert the aluminum oxide to aluminum fluoride. Water (H2O) is produced as a byproduct. In this way the HF works as a polishing agent to make the aluminum "shiny" again. Depending on the concentrationof the HF, the contact time, and temperature, the HF can continue to react with the aluminum and corrode it.
Why can't we use aluminum for melting gold?
Aluminum has a lower melting point than gold, so it would melt before the gold does. This would make it difficult to separate the two metals based on their melting points. Additionally, aluminum can form alloys with gold, which can affect the purity of the final product.
What takes more space a kilogram of gold or a kilogram of aluminum?
aluminum
What is oxidized in galvanic cell with aluminum and gold electrode?
The aluminum metals
Which has more volume -- a kilogram of gold or a kilogram of aluminum?
A kilogram of gold and a kilogram of aluminum have the same volume because they both weigh the same. Density is the property that determines how much space a substance occupies for a given mass, and because gold is denser than aluminum, a smaller volume of gold will weigh the same as aluminum.
