What happens when a piece of zinc metal is added to copper sulphate solution

SO4 is sulfate. It's one of the most common polyatomic anions, so this might be good to memorize. Oxygen and Sulfur both have 6 valence electrons. In order to be stable Oxygen needs to make 2 bonds, so Sulfur has to bond with all of them. See the issue yet? Sulfur can only make 6 bonds with 6 electrons, but 4 Oxygens would require it to make 8 bonds. Sulfur has a 'charge' of 6+ and the Oxygen has a 'charge' of 8-. In order for the molecule to be formed it has to take 2 electrons from some other atom/molecule. Doing so allows it to form SO4(2-) The sulfate is composed of sulfur and oxygen atoms which are much more electronegative than copper. Copper doesn't possess enough electronegativity to take electrons from such an electronegative anion. Copper does have more electronegativity than zinc which is why copper takes electrons from zinc instead. Hope that helps. So what we have here is a solution of a copper sulfate. And copper sulfate is an ionic compound. The copper loses two electrons to the sulfate. So the copper has a positive 2 charge, and the sulfate has a negative 2 charge. This is a cation. This is an anion. So you could imagine it's very easy to dissolve it in a polar solvent like water. So this is an aqueous solution. We are dissolving it in water, and it actually does have this blue color. So one way to think about it is this is a bunch of copper cations dissolved in water and a bunch of sulfate anions also dissolved in this water right over here. Now, we're goi...

Answer: Zinc displaces copper from copper sulphate and generates zinc sulphate solution when added to CuSO 4 solution because zinc is a more reactive metal that displaces less reactive metal from its solution. A color change from blue to colorless indicates this. The color of CuSO 4 solution is blue, while ZnSO 4 The solution is colorless. The chemical equation of the reaction, Zn + CuSO 4 → ZnSO 4 + Cu. • What is the formula for a3+b3? • In Indian rupees, 1 trillion is equal to how many crores? • Name the smallest and the largest cell in the human body • Examples of herbs, shrubs, climbers, creepers • How do we convert 1 g/cm3 to kg/m3 • What is the molecular mass of glucose molecules (C6H12O6) • Find five rational numbers between 2/3 and 4/5 • How many zeros are there in 1 lakh?

Table of Contents • • • • • • What happens when zinc is added to copper solution? Thus when zinc granules are added to the solution of copper sulfate, zinc displaces copper to form zinc sulfate and thus copper gets deposited. In this reaction, zinc metal can easily displace the copper metal from its salt to form an aqueous solution of zinc sulfate. What does pure copper react with? Pure copper is soft and malleable; a freshly exposed surface has a reddish-orange color. It does not react with water, but reacts slowly with atmospheric oxygen, forming a layer of brown-black copper oxide. In contrast to the oxidation of iron by wet air, this oxide layer stops further corrosion. When zinc and copper are mixed we get? Brass is a homogeneous mixture. It’s made when copper and zinc are mixed. It’s called a homogeneous mixture because it looks the same throughout. and molecular weight is 321.42 gm. What happens when a piece of zinc metal is added to dilute hydrochloric acid? When dilute hydrochloric acid is added to granulated zinc placed in a test tube, zinc metal is converted to zinc chloride and hydrogen gas is evolved in the reaction. In the reaction we can see that a zinc chloride salt is formed and hydrogen gas is evolved. The evolved hydrogen gas is colourless and odourless. What happens when the copper reacts with air explain? Copper oxidizes to copper When copper is heated in air, it is oxidised to copper (II) oxide and the reddish brown metal turns black as the copper is ...

\( \newcommand\) • • Gold and silver are widely used metals for making jewelry. One of the reasons these metals are employed for this purpose is that they are very unreactive. They do not react in contact with most other metals, so they are more likely to stay in tact under challenging conditions. No onewants their favorite piece of jewelry to fall apart! Direct Redox Reactions When a strip of zinc metal is placed into a blue solution of copper (II) sulfate (figure below), a reaction immediately begins as the zinc strip begins to darken. If left in the solution for a longer period of time, the zinc will gradually decay due to oxidation to zinc ions. At the same time, the copper (II) ions from the solution are reduced to copper metal (see second figure below), which causes the blue copper (II) sulfate solution to become colorless. Figure \(\PageIndex\) Notice that zinc is listed above copper on the activity series. which means that zinc is more easily oxidized than copper. That is why copper (II) ions can act as an oxidizing agent when put into contact with zinc metal. Ions of any metal that is below zinc, such as lead or silver, would oxidize the zinc in a similar reaction. These types of reactions are called direct redox reactions because the electrons flow directly from the atoms of one metal to the cations of the other metal. However, no reaction will occur if a strip of copper metal is placed into a solution of zinc ions, because the zinc ions are not able to oxidize t...
