What effects does phosphoric acid have on the human body?
It dissolves your teeth and gradually your skeleton.
Does copper dissolve in acid?
Copper dissolves in any oxidising acid like nitric acid.
What dissolves copper the quickest?
Nitric acid , not very concentrated.
What is the reaction of phosphoric acid with nitric acid?
phosphoric acid
What is the chemical formula for copper 2 chloride and phosphoric acid forms copper phosphate?
Copper (II) Chloride is CuCl2
Will cola clean a copper penny?
Soda pop is a mild acid, because of dissolved carbon dioxide. Acid dissolves the copper oxide tarnish that darkens the penny's color.
What acid is there in coke that helps clean a penny?
This is the phosphoric acid.
What effects does phosphoric acid have on the human body?
It dissolves your teeth and gradually your skeleton.
Which liquid dissolves the penny fastest?
Some strong acid such as H2SO4 (Sulfuric) probably would dissolve copper bronze the quickest.
Does copper dissolve in acid?
Copper dissolves in any oxidising acid like nitric acid.
Why phosphoric acid dissolves into ions in water if it is a molecular compound?
[Ca3(PO4)2]
Do copper pennies rust in soda or vinegar faster?
Pennies don't rust; they're copper. They corrode. The phosphoric acid, carbonation and salt in soda will corrode a penny faster than the other liquids.
Does acid dissolve in acid?
Copper dissolves in any oxidising acid like nitric acid.
What dissolves copper the quickest?
Nitric acid , not very concentrated.
What is the chemical reaction in cleaning a penny?
A copper penny builds up a layer of corrosion on its outsides. Probably copper oxide. The cleaning just dissolves the outer corrosion and leaves a new outer layer of copper. CuO + HNO3 --> Cu(NO3)2 + H2O ... the copper nitrate is dissolved in the acid solution and leaves 'clean' copper behind.
How potato battery invented?
What is a potato and how can it make a voltage?A potato is a South American herb that is a member of the nightshade family. People eat the starchy tuber of the vegetable. So how can a potato create a voltage? Potatoes contain phosphoric acid. It's the acid in the potato that allows a chemical reaction to take place. The potato battery works when a copper penny and a zinc-coated nail are placed in contact with the phosphoric acid inside the potato. The nail and the penny become the battery's terminals or electrodes. The acid reacts with the copper and removes electrons. The copper penny ends up missing some electrons, which gives it a slightly positive charge. The acid also reacts with the zinc nail. In this case the acid dissolves the zinc and leaves some of its electrons behind on the nail. The excess electrons on the nail and the lack of electrons on the penny result in the creation of voltage in the system. If the nail and the copper penny are connected together with a wire, the excess electrons move from the zinc nail to the positive charge on the penny. These moving electrons are called electrical current.
What are diamonds soluble in and why?
Outside a laboratory, where someone would develop a chemical that would dissolve a diamond, nothing dissolves a diamond.
