Yes, because the orange juice has an acidic pH. When you mix an acid (orange juice), with a reactive metal (aluminum) they react, the aluminum slowly dissolves into the orange juice. This would give it a horrible taste and it probably wouldn't be safe to consume.
The metals present in bronze are copper and zinc. Though copper does not react with dilute acids, zinc does.
The two do not react. Zinc is more active than copper and thus copper can not displace zinc.
Copper slowly reacts with air to form copper oxide. If you have a copper penny and see dark "dirty" patches on it, this is copper oxide. Citric acid, found in some fruit juices, will dissolve copper oxide, which is why coin collectors wash copper coins in lemon juice.
No. Zinc and aluminum will react though.
zinc is more reactive than copper hence it displaces the copper in copper sulphate solution to become zinc sulphate and copper metal is formed
no
zinc and iron
Zinc is used to precipitate gold from gold cyanide. Zinc will react to form zinc cyanide.
No.
They could, since magnesium is more reactive than copper, and could displace it to form magnesium nitrate.
yes cos there is loads of pikachus present
