What is the reaction between copper sulphate and potassium iodide?
What is the reaction between copper sulphate and potassium iodide?
(c) Copper sulphate on treatment with potassium iodide precipitates cuprous iodide (Cu2I2), liberates iodine gas and also forms potassium sulphate.
What is the word equation for copper sulphate?
Copper sulfate | CuSO4 – PubChem.
What is the word equation of CuO?
Copper(II) oxide or cupric oxide is an inorganic compound with the formula CuO. A black solid, it is one of the two stable oxides of copper, the other being Cu2O or copper(I) oxide (cuprous oxide).
What is the word equation for iron and copper sulphate?
Fe + CuSO₄ = FeSO₄ + Cu (iron displaces copper in the salt solution; the iron dissolves, turning into solution, and metallic copper of a reddish color is released).
What is the formula for copper iodide?
CuICopper(I) iodide / Formula
What is Cu2I2?
Copper iodide copper | Cu2I2 – PubChem.
What does a word equation show?
A word equation represents a chemical reaction using the names of the substances involved. Word equations do not show any chemical symbols or formulae . In a chemical reaction, reactants are the substances that react together, and products are the substances formed.
What is the word equation for iron and copper oxide?
Copper iron oxide | CuFe2O4 – PubChem.
What type of equation is Fe CuSO4 FeSO4 Cu?
displacement reaction
Fe + CuSO4(aq) → FeSO4(aq) + Cu(s) The type of reaction is a displacement reaction. In this reaction, the highly reactive metal iron replaces the Copper in copper sulphate by giving up two electrons and gets oxidized and forms a new compound called ferrous sulphate.
What is the formula of potassium sulfate?
K2SO4Potassium sulfate / Formula
Is CuI and Cu2I2 same?
No difference between the two. CuI is an ionic, crystalline compound. It doesn’t form discrete molecules of CuI, or of Cu2I2 for that matter. CuI is used because it is the simplest way to represent the ratio of copper and iodide ions in the compound.

How do you write a word equation?
Word equations follow certain rules…
- Reactants always go first in word equations, and the names of the reactants are separated using + symbols.
- After the reactants, there is an arrow, →, to show that the chemical reaction has taken place.
- The products are written after the arrow, separated by + symbols.
How do you write a word equation for a reaction?
Word equations
- Word equations always take this form:
- reactants → products.
- A + sign separates two or more reactants, or two or more products.
What is the equation for the dehydration of CuSO4 5h20?
The hydrated form is medium blue, and the dehydrated solid is light blue. The balanced equation is: Heat CuSO4·5 H2O(s) ——-> CuSO4(s) + 5 H2O(g) If 2.42 g CuSO4·5 H2O is decomposed to CuSO4, predict the mass of the remaining light blue solid in grams.
What is the word equation for copper II sulfate pentahydrate?
Copper sulfate pentahydrate | CuSO4. 5H2O – PubChem.

What is the balanced equation for copper sulfate and potassium iodide?
2CuSO 4 + 4KI → 2CuI + I 2 + 2K 2 SO 4 [ Check the balance ] Copper sulfate react with potassium iodide to produce copper (I) iodide, iodine and potassium sulfate. The reaction proceeds at room temperature.
What happens when copper sulphate reacts with potassium iodide?
Copper sulphate on treatment with potassium iodide precipitates cuprous iodide ( C u I), liberates iodide gas and also forms potassium sulphate. Hint: A chemical reaction is said to be balanced when it has equal number of atoms of each element on both reactant side and product side.
What is the chemical formula of copper (ll) iodide?
So the chemical formula of Copper (ll) iodide is C u I 2. Note: C u I 2 is unstable. The iodide will reduce C u 2 + to C u +. it decomposes readily into CuI and I 2 . Hope it helps. Note: I put space between the number of atoms with its charge.
What ion is reduced by iodide to copper (I)?
Copper ions are reduced by the iodide ions to copper(I). The best way to look at this is via the half equations: Cu2+ + 1e –> Cu+. 2I- –> I2 + 2e.
