In general, copper will not displace hydrogen from water or from acids, but in the case of hot, concentration H2SO4 a reaction will occur with copper. Why? Because hot, concentrated H2SO4 will act as an oxidizing agent to oxidize the copper to copper cation. HCl cannot do this.
What else can I help you with?
What is formed by CuSO4 plus HCl?
When copper sulfate (CuSO4) reacts with hydrochloric acid (HCl), copper chloride (CuCl2) and sulfuric acid (H2SO4) are formed as products. The balanced chemical equation for this reaction is CuSO4 + 2HCl -> CuCl2 + H2SO4.
Why copper does not react with hcl?
Copper does not react with hydrochloric acid (HCl) because it is less reactive than hydrogen. It forms a passive layer of copper chloride (CuCl2) on its surface, which protects the copper underneath from further reaction with the acid.
HCL CUSO4 equation?
The chemical equation for the reaction between hydrochloric acid (HCl) and copper (II) sulfate (CuSO4) is: 2 HCl + CuSO4 -> CuCl2 + H2SO4
Why use h2so4 instead of hcl in titration of kmno4?
H2SO4 is typically used instead of HCl in the titration of KMnO4 because HCl can react with KMnO4 and form chlorine gas, which can interfere with the titration results. Additionally, H2SO4 provides the required acidic medium for the reaction to occur between KMnO4 and the analyte.
Which acids dissolve copper?
Acids known to dissolve copper include hydrochloric acid (HCl), nitric acid (HNO3), and sulfuric acid (H2SO4). These acids can react with copper to form soluble copper compounds, allowing the metal to dissolve.
What is formed by CuSO4 plus HCl?
When copper sulfate (CuSO4) reacts with hydrochloric acid (HCl), copper chloride (CuCl2) and sulfuric acid (H2SO4) are formed as products. The balanced chemical equation for this reaction is CuSO4 + 2HCl -> CuCl2 + H2SO4.
What happen when copper react with dilute HCL?
It forms copper chloride and water.
Why copper does not react with hcl?
Copper does not react with hydrochloric acid (HCl) because it is less reactive than hydrogen. It forms a passive layer of copper chloride (CuCl2) on its surface, which protects the copper underneath from further reaction with the acid.

Which gas can be smelled when H2SO4 is added to copper chloride solution?
The chemical reaction is:CuCl2 + H2SO4 = CuSO4 + 2 HCl(g)The gas is hydrogen chloride.
Which acids dissolve copper?
Acids known to dissolve copper include hydrochloric acid (HCl), nitric acid (HNO3), and sulfuric acid (H2SO4). These acids can react with copper to form soluble copper compounds, allowing the metal to dissolve.
Does a new penny float in hcl?
when the penny is reacted with HCl, there must be somesort of area where the copper on the outside of the penny is removed so that the HCl can react with the zinc inside because HCl does not react with copper. Once the HCl reacts with the Zn inside, it will dissapear and therefore become less dense then the ZnCl2 that is formed which causes the penny to float
Why do minerals and HCl not react?
Minerals are typically composed of stable compounds that do not react with hydrochloric acid (HCl). HCl is a relatively weak acid compared to other acids that can dissolve minerals, such as sulfuric acid (H2SO4). Additionally, some minerals may also form a passive layer on their surface that can inhibit the reaction with HCl.
Why HCl and HNO3 can be used in combination but HCl and H2SO4 not?
this is because when hcl and hno3 is mixed then it ionizes into h+and cl- and and and you may knaw rust is the mixing of foriegn particles in the pure substances. eg-fe+o2=fe2o3 so when gold is mixed with hcl and hnoc the it gives off aucl4. ie au pure gold is mixed with the pollutant cl4 similarly when h2so4 cant be used because s04 is not the neutral radical like no3 of hno3 thus s04 not being neutral and no3 being neutral h2so4 cant be used
Why do not use Hcl instead of H2SO4 in preparation of potassium permanganate?
Hydrochloric acid (HCl) may react with the potassium permanganate produced, leading to undesirable side reactions. Sulfuric acid (H2SO4) is chosen because it is a non-oxidizing acid that maintains the stability and purity of the final product.
Which doesnt belong HCL and H2SO4 and Vinegar and Milk of magnesia?
milk of magnesia.it is a base.Others are acids.
