Question

CuSO4+NaOH-->CuSO4+HCl-->CuSO4+BaCl-->CuSO4+Fe-->а также: ТОЛЬКО 1 полную ионную и краткую связь показать.ВЫВОД:

Answer 1

СuSO4 + 2NaOH = Cu(OH)2↓ + Na2SO4

CuSO4+HCl--> не идет

CuSO4 + BaCl2 = CuCl2 + BaSO4↓

Cu(2+) + SO4(2-) + Ba(2+) + 2Cl(-) = Cu(2+) + 2Cl(-) + BaSO4↓
SO4(2-) + Ba(2+) = BaSO4↓

СuSO4 + Fe = FeSO4 + Cu

 

Данная соль - сульфат меди вступает в реакции со щелочью с образованием новой соли и нерастворимого основания,  с другой солью, с образованием белого осадка, это качественная реакция на сульфат ионы и с железом в реакцию обмена. С соляной кислотой соль не реагирует, так как медь стоит после водорода в электрохимическом ряду напряженности металлов, поэтому не может вытеснить водород из кислоты.

Answer 2

Reaction: CuSO4 + NaOH -> CuSO4 + HCl -> CuSO4 + BaCl -> CuSO4 + Fe

The given reaction involves a series of chemical reactions with CuSO4 (copper sulfate) as the starting compound. Let's break down each step and analyze the reactions.

1. CuSO4 + NaOH: - In this step, copper sulfate (CuSO4) reacts with sodium hydroxide (NaOH). - The reaction does not result in any significant chemical change, as both CuSO4 and NaOH remain unchanged. - The reaction can be represented by the ionic equation: CuSO4 + 2NaOH -> CuSO4 + 2NaOH.

2. CuSO4 + HCl: - In this step, copper sulfate (CuSO4) reacts with hydrochloric acid (HCl). - The reaction results in the formation of copper chloride (CuCl2) and sulfuric acid (H2SO4). - The balanced chemical equation for this reaction is: CuSO4 + 2HCl -> CuCl2 + H2SO4.

3. CuSO4 + BaCl: - In this step, copper sulfate (CuSO4) reacts with barium chloride (BaCl2). - The reaction results in the formation of copper chloride (CuCl2) and barium sulfate (BaSO4). - The balanced chemical equation for this reaction is: CuSO4 + BaCl2 -> CuCl2 + BaSO4.

4. CuSO4 + Fe: - In this step, copper sulfate (CuSO4) reacts with iron (Fe). - The reaction results in the displacement of copper by iron, forming iron sulfate (FeSO4) and copper metal (Cu). - The balanced chemical equation for this reaction is: CuSO4 + Fe -> FeSO4 + Cu.

Ionic Equations:

1. CuSO4 + NaOH -> CuSO4 + 2NaOH 2. CuSO4 + 2HCl -> CuCl2 + H2SO4 3. CuSO4 + BaCl2 -> CuCl2 + BaSO4
