What will happen if aluminum is mixed with copper?
If a mixture of the right amount of aluminum and copper is lit on fire at a high enough temperature then it can produce Thermite, which burns at an extremely high temperature.
How do you make potassium polysulfide?
reduction od potassium sulfate by reducing agents such as hydrogen and carbon monoxide at high temperature.
How do you get copper out of malachite?
In order to extract copper from malachite, the malachite must be heated to a high temperature. This produces a fine black powder (copper Oxide). The copper oxide is heated again to a more extreme temperature, this removes the oxygen, leaving metallic copper.
What is the difference between a copper rich ore and a low grade ore?
Copper rich ores contain Relatively large amount of copper. Copper obtained from rich ores is from better quality than low-grade ores. A low-grade ore doesn't contain very high proportion of valuable copper
What metal makes purple?
heating copper to a very high temperature and letting it air cool can result is a purple hue.
How do you ensure all water is removed from hydrated copper sulfate?
Heat it in a crucible to a high temperature (well above the boiling point of water). Hydrated copper sulfate is blue in color; when it turns white you will know that the water has been driven out.
Does copper melt at high temperature?
Yes.

Does copper metal burn?
Yes, at a high enough temperature Copper will burn and combine with Oxygen to form Copper oxide.
Is Magnesium melting point above room temperature?
Magnesium sulfate doesn't melt; at high temperature MgSO4 is thermally decomposed.
What is McNeill's process?
McNeil's process is an electrochemical method used for copper refining. It involves the deposition of purified copper from a copper sulfate solution onto a cathode, which helps to produce high-purity copper suitable for electronic applications.
Is magnesium sulphate's melting point above room temperature?
Magnesium sulfate doesn't melt; at high temperature MgSO4 is thermally decomposed.
distinguish the true and false copper core?
It can be burned with fire. If it can withstand high temperature, it must be real copper.
How do you make potassium polysulfide?
reduction od potassium sulfate by reducing agents such as hydrogen and carbon monoxide at high temperature.
Is beryllium a solid at room temperature?
Barium is a solid at room temperature, and has a melting point of 727°C. Barium at room temperature is explosively combustible, especially as powder, due to its extreme reactivity with oxygen in the air. Barium sulfate is used in medical radiology, and barium is used with yttrium in YBCO high-temperature superconducting compounds (yttrium barium copper oxide).
How to Purify Copper by Plating?
The process of plating copper is relatively simple with the right materials and know-how. This tutorial will cover a basic copper plating procedure which is used on a large industrial scale to achieve high-purity copper.There are several materials needed for this process. The first and most obvious is the impure copper to be refined. Also needed will be copper II sulfate, water, a DC power source, and some lengths of wire.The first step is to make a saturated solution of copper II sulfate, which has a maximum solubility of 316g per liter of water. The final solution should be dark blue.Two copper electrodes are then introduced into the copper sulfate bath. One of these electrodes consists of the impure copper sample and the other is simply a copper wire.The DC power source is applied to the two electrodes. The positive side (anode) of the supply is connected to the impure copper block while the negative side (cathode) is attached to the copper wire.Copper has only positive oxidation states and is therefore attracted to the negative electrode. Pure copper is pulled from the solution of copper sulfate and attaches itself to the wire electrode, breaking the sulfate anion off and creating a weak solution of sulfuric acid. The acid then eats at the impure copper, turning it into more copper sulfate. Effectively, the copper from the impure anode is transferred to the cathode, leaving all its impurities behind. The copper plated onto the cathode will be very pure.Cell current should be monitored carefully as high current causes hydrogen bubbles to form on the cathode and will inhibit the growth of the pure copper. If the power supply does not have a current limiting adjustment, the spacing between the anode and cathode can be varied to regulate the current. The closer the electrodes, the higher the current flow and vice versa.Never dispose of the used copper sulfate down the drain as it is an environmental hazard. Simply evaporate the solution to recover the copper sulfate for later use.
Which wire would have the lowest resistance a long thin iron wire at a high temperature or a short thick copper wire at a low temperature?
Copper will.
