copper (thiocyanate)2 and potassium nitrate
Copper nitrate contains copper, nitrogen, and oxygen elements. The chemical formula for copper nitrate is Cu(NO3)2.
Cu(No3)2 is the formula for copper nitrate compund
It would produce Silver and a blue solid called Copper Nitrate (Cu(NO3)2). It is caused by a replacement reaction where Copper replaced Silver in Copper Nitrate. The equation goes like this: Cu + Ag(NO3)2 → Ag + Cu(NO3)2
The chemical formula of copper(II) nitrate is Cu(NO3)2.
When copper is added to silver nitrate, a single displacement reaction occurs. The copper will displace the silver in the compound, forming copper(II) nitrate and silver. The silver will precipitate out of solution as a solid.
This is the basic copper carbonate - Cu2(OH)2CO3.
No, hydrogen gas is not produced when copper reacts with silver nitrate. In this reaction, copper replaces silver in the silver nitrate solution, resulting in the formation of copper(II) nitrate and silver metal.
Cu + 2HNO3 --> Cu(NO3)2 + H2Looks like copper nitrate.
On addition of the KI to your copper (II) solution, you formed Copper (I) iodine solid and produced the tri-iodide ion. It is the tri-iodide ion that you are titrating with the sodium thiosulfate. The tri-iodine ion is what itercalates into the starch molecules to form the dark blue color you are using as an end point in the titration. Some the the tri-iodide ion formed will adsorb to the surface of the solid copper (I) iodine formed. This must be desorbed for a complete titration. The addition of the potassium thiocyanate, displaces the adsorbed tri-iodine ion, and liberates it for titration.

Your balanced chemical equation for this double replacement reaction would be: Cu(NO3)2 + 2KOH ----> Cu(OH)2 + 2KNO3 Therefore, you would end up with copper II hydroxide and potassium nitrate.
Cu2I2 is precipitates in light pink colour due to adsorption of I2 and the precipitate releases I2 very slowly. Therefore very small amount of potassium thiocyanate is added towards the end point which helps to displace the adsorbed I2 quickly by combining with Cu2I2 to form CuSCN which has less tendency to adsorb I2.
Ammonium thiocyanate is used as an indicator in the iodometry of copper because it forms a red complex with copper ions. By adding ammonium thiocyanate to the copper solution, the color change from white to red indicates the end point of the titration, allowing for the determination of copper concentration.
Cu2CuN2S2
Yes, magnesium reacts with copper nitrate to form magnesium nitrate and copper. The reaction involves the displacement of copper from the copper nitrate solution by magnesium.
The chemical formula for the compound formed by the reaction of copper(II) ions with thiocyanate ions is CuSCN.
copper nitrate is also called as cupric nitrate
