Does vinegar dissolve zinc?
The Cu2+ in the salt/vinegar solution reacts with the zinc metal and causes zinc metal to dissolve. … Reaction 1 is observed because zinc is higher up on the activity series of metal than hydrogen. Reaction 2 is observed because zinc is higher up on the activity series of metal than copper.
Why does water rust a nail?
The causes of corrosion require the presence of water and oxygen. Water can combine with carbon dioxide in the air to form carbonic acid, a weak acid. … Then, the water will begin to break down into hydrogen and oxygen. Free oxygen reacts with dissolved iron to form iron oxide, and iron oxide is rust.
Does Coca Cola dissolve meat?
The phosphoric acid in carbonated drinks such as Coca Cola makes it very acidic. It has a pH level around 2.7. The pH of our stomach is normally between 1.5 and 3.5 and it can dissolve meat.

That’s because cola has acid in it – phosphoric acid, to be precise. Most colas have a pH of 2.5-3.5. … When the copper oxide (the pennies) and the phosphoric acid (the cola) get together in the bath, the acid reacts with the copper oxide on the pennies and dissolves it. That’s why the pennies get shiny.

What type of nails rust the fastest?
Patina, the reaction of copper to saltwater or air, was visable in the water and on the nails. The galvanized nails in both salt and freshwater started to corrode and black spots were visable o the galvanized nails. My hypothesis was correct, iron nails rust the fastest in both salt and freshwater.
What can dissolve zinc?
It is also soluble in ammonium hydroxide, alkali, hydrochloric acid and nitric acid, slightly soluble in aqueous hydrofluoric acid, and insoluble in ammonia. Zinc hydroxide can be precipitated from zinc solutions by addition of bases.
Why does vinegar rust a nail?
Vinegar speeds up rusting because it contains a dilute form of acetic acid; positive hydrogen ions in the acid remove electrons from iron, ionizing it and making it susceptible to rust. … Although bleach and vinegar both accelerate rusting, do not combine the two, as the mixture releases toxic chlorine gas.
