What scientific conclusion can be made about combining Copper Chloride and Aluminum Foil?

The two are highly reactive when mixed in water. If you add aluminum to a water solution of copper chloride, the aluminum will be combined as aluminum chloride gas, releasing the copper into the water. The mixture will turn very hot, bubble up, and start to smoke, and the color will change from blue to dark red. ========================= The first sentence is correct, the two are highly reactive, but from there on, there are problems... There's no such thing as aluminum chloride gas. There is a gas given off, but it is hydrogen gas. The "smoke" is actually tiny droplets of water condensed from water vapor. It gets that hot. The red color is due to the formation of copper metal a Cu2+ ions are reduced to the metal as aluminum metal is oxidized. Aluminum metal has a thin coating of aluminum oxide, Al2O3, covering the surface. Even freshly scraped aluminum metal will quickly reform the passivating layer of aluminum oxide. So in many solutions, the layer of Al2O3 prevents any aluminum metal from reacting. If aluminum metal is placed in a solution of copper(II) sulfate, you will not get a reaction. No copper metal will form on the aluminum. But when placed in copper(II) chloride, aluminum will give a vigorous reaction with a lot of heat and hydrogen gas being given off. The reason is the chloride ion. In the presence of chloride ion, the Al2O3 layer dissolves forming the AlCl4^- in solution and exposing a fresh layer of aluminum metal. The aluminum metal will reduce copper(II) ions to copper metal, AND the aluminum metal will react with water very much like an alkali metal reacts with water, vigorously, with a lot of heat given off, and with the formation of hydrogen gas. Al2O3 + 8Cl- + 3H2O --> 2AlCl4^- + 6OH- Al(s) + OH- + 2H2O --> Al(OH)3(s) + H2(g) 2Al(s) + 3Cu2+ --> 2Al3+ + 3Cu(s)


If you add hydrogen chlorine what do you get?

When hydrogen and chlorine combine, they form hydrochloric acid (HCl), a strong acid that is commonly used in industrial and laboratory settings. This reaction is exothermic and releases energy in the form of heat.


Experiment catalase enzyme in test tube with sand and H2O2?

sand is not a biological tissue but if you add catalase and hydrogen peroxide together, oxygen and water will be formed. This is a process happening in every organ in every organism (especially in the liver) to break down toxic substances like hydrogen peroxide to less reactive substances: oxygen and water.


What is the test to show if hydrogen chloride contains chloride ions?

Add silver nitrate to it. Silver chloride which is. A white ppt will form. This shows that chloride ion is present.


What happens when you combine fluorine and hydrogen?

When you add fluorine and chlorine together, a chemical reaction happens; during this reaction the fluorine reacts with chlorine and the iodide (a less reactive halogen) is left in the solution. During the reaction, you'd expect to see bubbles and fizzing. Hope this helped Mohsin, 16 - HNC

How get back copper from nitric acid?

To recover copper from nitric acid, you can add a reducing agent such as iron or zinc to the solution. The copper will be displaced from the nitric acid and form a solid precipitate, which can then be filtered out. This process is known as cementation or displacement reaction.


What is the word equation when you add metal to acid?

When a metal is added to an acid, it typically forms a metal salt and hydrogen gas. The general word equation is: metal + acid → metal salt + hydrogen gas.


What happens when you add acid to metal?

When you add acid to metal, a chemical reaction occurs in which the metal reacts with the acid to form metal salts and hydrogen gas. The metal atoms lose electrons to form cations, which then react with the anions of the acid to form the metal salt. The release of hydrogen gas is a characteristic of this type of reaction.


How do you displace silver from copper sulphate solution?

To displace silver from a copper sulfate solution, you can add metallic copper to the solution. The more reactive copper will displace the less reactive silver, leading to the formation of copper sulfate and elemental silver. This is based on the principle of displacement reactions in which a more reactive metal displaces a less reactive metal from its compound.


How do you naming binary?

Shorten hydrogen to hydro, then use the other non-metal name then add ic eg Hydrogen chloride - hydrochloric acid


What products form if you add hydrochloric acid to magnesium metal?

When hydrochloric acid is added to magnesium metal, magnesium chloride and hydrogen gas are produced. This is a displacement reaction where the magnesium metal displaces the hydrogen in hydrochloric acid to form magnesium chloride.


Why does a pop sound happen when you add heat on top of the magnesium metal and hydrochloric acid?

reacts with hydrogen gas given off.


When you add zinc metal to hyrochloric acid does a chemical physical change occur?

Yes, hydrogen gas and zinc chloride are produced


What happens when you add hydrochloric acid to copper?

When hydrochloric acid is added to copper, a redox reaction occurs, resulting in the formation of copper chloride and hydrogen gas. The copper metal reacts with the hydrochloric acid to form copper (II) chloride solution and hydrogen gas is also produced. This reaction can be represented by the equation: 2 HCl + Cu -> CuCl2 + H2


What is the metal which it would be dangerous to add to dilute hydrochloric acid?

Adding reactive metals such as sodium, potassium, or magnesium to dilute hydrochloric acid can be dangerous as it can produce hydrogen gas rapidly, leading to a potential explosion hazard. Additionally, the reaction can be highly exothermic, resulting in heat generation.
