What else can I help you with?
What acid would you use to make copper sulfate?
Sulfuric Acid. The chemical reaction is Cu + 2H2SO4 = CuSO4 + SO2 + 2H2O
Can nitric acid melt brass?
Yes, brass is an alloy of copper and zinc, and nitric acid cant "melt" (ie oxidize) both of them. The reaction releases dangerous fumes of nitrogen dioxide and must be performed in a fume hood.
What will happen when you react copper oxide with and acid?
When copper oxide is reacted with an acid such as hydrochloric acid, a chemical reaction occurs to form copper chloride and water. The copper oxide is neutralized by the acid, leading to the formation of a salt and water as products.
Is the reaction of copper and acid a chemical or physical change?
The reaction of copper with acid is a chemical change because new substances are formed after the reaction takes place. Copper reacts with acid to form copper ions and hydrogen gas, which are different from the original copper and acid.
What would you get if you mixed copper with hydrochloric acid?
Mixing copper with hydrochloric acid would produce copper chloride and hydrogen gas. This reaction would dissolve the copper, forming a blue-green solution of copper chloride. The release of hydrogen gas could be observed as bubbles.
How would you melt copper?
With heat.
Can you use acid too melt PVC off copper cable?
It is not recommended to use acid to melt PVC off copper cable as this can release harmful fumes and be dangerous. Instead, it is better to use a mechanical method such as cutting or stripping the PVC off the copper cable to avoid any health hazards.
How would the crystals of copper sulphate be prepared?
melt the copper sulfate and see what appers
How long will it take for a new zealand coin take to melt in acid?
A coin would dissolve in an acid, not melt. The time taken would depend on the size of the coin, its composition, and the acid used.
What acid would you use to make copper sulfate?
Sulfuric Acid. The chemical reaction is Cu + 2H2SO4 = CuSO4 + SO2 + 2H2O
How much energy is required to melt to kilograms of copper?
The energy required to melt 1 kg of copper at its melting point of about 1084°C is approximately 205 kJ. Therefore, to melt 2 kg of copper, you would need around 410 kJ of energy.
What will happen when you react copper oxide with and acid?
When copper oxide is reacted with an acid such as hydrochloric acid, a chemical reaction occurs to form copper chloride and water. The copper oxide is neutralized by the acid, leading to the formation of a salt and water as products.

Are copper roofs affected by acid rain?
Yes, copper roofs can be affected by acid rain. Acid rain can cause corrosion and pitting on copper surfaces, leading to a greenish patina forming on the roof over time. Regular maintenance and protective coatings can help mitigate the effects of acid rain on copper roofs.
Is the reaction of copper and acid a chemical or physical change?
The reaction of copper with acid is a chemical change because new substances are formed after the reaction takes place. Copper reacts with acid to form copper ions and hydrogen gas, which are different from the original copper and acid.
Will copper coin melt on 100 degree if put on gas fire for 12 hrs?
Copper melts at around 1984°F (1085°C), so it is unlikely that a copper coin would melt on a gas fire at 100°F (37.8°C) in 12 hours. The temperature would need to be significantly higher to melt copper.
What would you get if you mixed copper with hydrochloric acid?
Mixing copper with hydrochloric acid would produce copper chloride and hydrogen gas. This reaction would dissolve the copper, forming a blue-green solution of copper chloride. The release of hydrogen gas could be observed as bubbles.
