Red sclae residue ( COPPER II ) partly dissolves in dilute acid to form a pale blue solution. Name the pale blue solution and give chemical equation to support your answer
The dilute acid we're talking about here is H2SO4. So the reactants involved are Cu and H2SO4.
The product of this reaction is CuSO4ยท5H2O. This is the pale blue solution.
Thank you sir.. You made my day :D
Is Cu + 2H2So4 = Cuso4 + 2so2 + 2h20
The pale blue solution formed when red scale residue, which is primarily composed of copper(II) oxide (CuO), partially dissolves in dilute acid is called copper(II) chloride (CuCl2) solution.
To obtain the chemical equation that supports this answer, we need to understand the reaction between copper(II) oxide and dilute acid. One common acid that reacts with copper(II) oxide is hydrochloric acid (HCl). When copper(II) oxide reacts with hydrochloric acid, it forms copper(II) chloride and water.
The chemical equation for this reaction can be represented as follows:
CuO (s) + 2HCl (aq) -> CuCl2 (aq) + H2O (l)
In this equation, CuO represents copper(II) oxide (solid), HCl represents hydrochloric acid (aqueous), CuCl2 represents copper(II) chloride (aqueous), and H2O represents water (liquid).
