Copper sulphate becomes a copper element, and what copper sulphate adds becomes copper

I guess you haven't been to high school yet, right?

According to the order table of metal activity, the more active metal can replace the less active metal.

The order of metal liveliness from strongest to weakest is k, ca, na, mg, al, zn, fe, sn, pb, (h), cu, hg, ag, pt, au (it is recommended that you memorize it, five as a group of memorization).

So you can choose any of MG, AL, ZN, FE, SN, PB. Taking fe as an example, the equation is fe+cuso4=cu+feso4

Why not choose k, ca, na, and you'll understand it when you get to high school, because they will react with water first.

I'll give you a metal mobility table :

k，ca，na，mg，al，mn，zn，gr，fe，si，sn，pb，（h），cu，hg，ag，pt，au。

Mg to Pb is fine, but with the exception of non-metallic silicon Si.

The equation is a simple trim, and it is not a complex redox, just write it yourself!

If you can replace copper, such as Fe, Al, Mg, etcA lot of it.

fe+cuso4=cu+feso4

As long as the reducibility is higher than copper, for example, iron.

fe+cuso4=cu+feso4

Copper sulphateAfter dissolving in water, it can react with active metals to form copper, which is a chemical reactionEquationsHere are some examples:

1. Reaction of copper sulfate with iron:cuso₄+fe=feso₄+cu2. Reaction of copper sulfate with aluminum:2al+3cuso₄=al₂(so₄)₃3cu

3. Reaction of copper sulfate with magnesium:mg+cuso₄=mgso₄+cu

1. Iron reacts with copper sulfate to form copper and ferrous sulfate.

2. Magnesium reacts with copper sulfate to form copper and magnesium sulfate.

3. Aluminum reacts with copper sulfate to form copper and aluminum sulfate.

4. Zinc reacts with copper sulfate to form copper and zinc sulfate.

1.Barium chloride bacl2

2.Carbon monoxide CO

3.Sodium hydroxide Naoh

4.Sodium hydroxide Naoh

Copper reacts with concentrated sulfuric acid, copper gradually dissolves, bubbles are formed, and the gas produced can make purple litmus turn red or the red solution fade. The solution is diluted blue after cooling.

1. Cu + 2Hso = Heating = Cuso + So + 2Ho2, the generated gas is introduced into the magenta solution, and the resulting phenomenon is: the magenta solution fades. 3. If it is introduced into the purple litmus test solution, the phenomenon produced is:

It turns red first, then fades to colorless. 4. Pour the liquid into a small amount of water after the reaction, the solution is blue, and the cuso solution is blue.

This reaction reflects the strong oxidizing and acidic properties of concentrated sulfuric acid. Concentrated sulfuric acid reacts with metals without hydrogen formation.

The chemical equation for the reaction of concentrated sulfuric acid and copper is: Cu + 2H2SO4 (concentrated) = CuSO4 + 2H2O + SO2. The phenomenon is that the copper gradually dissolves, bubbles are formed, and the gas produced can make the purple litmus turn red or the magenta solution fade, and the solution is diluted blue after cooling.

Concentrated sulfuric acid has strong oxidizing properties, which can oxidize the inactive metal copper. In this reaction, the valency of copper increases from 0 to +2, and it is oxidized by concentrated sulfuric acid, so concentrated sulfuric acid is used as an oxidant and copper is used as a reducing agent.

The phenomenon of the reaction of sulfuric acid and copper:The reaction phenomenon between copper and concentrated sulfuric acid is that bubbles will be formed, and the copper will be gradually dissolved, and the reaction solution will be diluted after cooling, and the solution will be blue. The gas produced by the reaction of copper with concentrated sulfuric acid can redden, or fade the magenta solution.

If there is an excess of concentrated sulfuric acid in the reaction, the surface of the copper will first turn black, forming a black turbidity, and then a white solution. After the copper has completely reacted, a grayish-white substance will settle at the bottom of the tube.

Acidic substances cannot displace the copper in the copper sulphate.

Metals that are more reactive than copper, such as zinc and iron, can be used to replace the copper in the copper sulfate solution.

Zinc flakes are placed in a copper sulfate solution.

Since metals such as zinc and iron are more active than copper, they can displace copper from the copper sulfate solution.

But very reactive metal potassium.

Sodium, etc., can react directly with water to form alkali and hydrogen gas, so they cannot replace the copper in the copper sulfate solution.

Displacement reaction. It is a chemical reaction in which an element reacts with a compound to form another element and a compound.

It is the four basic types of reaction in the chemistry of the reputation.

One of them, including the reaction of metal with salt solution, the reaction of metal with acid, etc.

There is no acid that can displace copper.

If it is not called replacement if you wish, zinc or iron can replace copper. )

Acids cannot replace copper.

Bubbles are created and the copper gradually dissolves. The reaction solution is diluted when cooled and the solution is blue. The gas produced by the reaction of copper with concentrated sulfuric acid can turn the purple litmus solution red or the magenta solution fade.

If there is too much concentrated sulfuric acid in the reaction, the surface of the copper will first turn black, forming a black turbid solution, and then a white solution. Copper reacts completely.

The equation for the chemical reaction of copper and concentrated sulfuric acid is as follows:Cu + 2H2SO4 (concentrated) = CuSO4 + SO2 + 2H2O (Condition: Heated).

The ionic reaction equation for copper and concentrated sulfuric acid is given belowCu + 2H2SO4 (concentrated) = Cu2+ +SO42- +SO2 + 2H2O (Condition: Heated).

Reaction of concentrated sulfuric acid with copper.

Copper sulfate can be obtained by reacting with a more active metal equilibrium salt solution.

The common ones are: 1. The reaction of copper with zinc sulfate solution can generate zinc and copper sulfate.

2. The reaction of copper and iron sulfate solution can cause Gaozi to generate iron and copper sulfate.

3. Copper reacts with tin sulfate solution to produce tin and copper sulfate.

Copper sulfate: white or off-white powder. The aqueous solution is weakly acidic and appears blue.

However, when crystallized from an aqueous solution, a blue copper sulfate pentahydrate, also known as alum, is formed, and this principle can be used to test the presence of water. It decomposes after losing crystal water after being heated, and is very stable at room temperature and pressure, without deliquescent, and will gradually weathered in dry air. Copper sulphate is an important raw material for the preparation of other copper-containing compounds.

Bordeaux liquid can be obtained by mixing with lime milk, which is used as a fungicide. It is also used as an electrolyte for electrolytic refining of copper.
