Copper Sulfate
When heated to 650 o C, CuSO 4 undergoes a decomposition reaction to yield cupric oxide (CuO) and SO 3 (sulfur xide). Copper sulfate is highly soluble in water, with solubility values of 1.055 molal and 1.502 molal ate 10 o C and 30 o C respectively.

Assertion :Copper does not react with dilute sulphuric acid, liberating
Assertion :Copper does not react with dilute sulphuric acid, liberating hydrogen. Reason: Copper is lower in reactivity series than hydrogen, or more fundamentally, because the magnitude of change in gibbs free energy when a single atom of elemental hydrogen ionizes is greater than the magnitude of the change in gibbs free energy when a single …

Hydrogen peroxide (H2O2) Reactions and Chemical Properties
So, hydrogen peroxide can react with many compounds. Hydrogen peroxide is oxidized to oxygen by strong oxidizing agents such as acidic KMnO 4 or K 2 CrO 4 or K Cr 2 O 7. Silver oxide is reduced to silver by hydrogen peroxide. Fe 2+ ions are oxidized to Fe 3+ ions. metal salts reaction with hydrogen peroxide.
Copper and Nitric Acid Reaction | Cu + HNO3
Why copper does not react with dilute HCl acid like dilute HNO 3 acid? HCl acid is not a oxidizing acid because chlorine atom in the HCl is -1 oxidation state. Therefore that chlorine atom does not reduce to show oxidizing acid characteristics. But in HNO 3, nitrogen is at +5 and it can be reduced to lower oxidation numbers.
Acid-base Behavior of the Oxides
Sodium Oxide. Sodium oxide is a simple strongly basic oxide. It is basic because it contains the oxide ion, O 2-, which is a very strong base with a high tendency to combine with hydrogen ions.. Reaction with water: Sodium oxide reacts exothermically with cold water to produce sodium hydroxide solution.A concentrated solution of sodium …

$begingroup$ @Avon97 That's exactly the thing that stumped me - while vinegar works, dilute sulfuric acid doesn't! Not even in a large excess as you suggested. The answer that I linked explains that vinegar reacts with hydrogen peroxide to form an organic peroxy acid which attacks the copper; sulfuric acid on the other hand doesn't do …

The statement that explains why CuO(s) + H2SO4(aq) reacts to give CuSO4(aq), while CuO(s) + K2SO4 does not give a product, is: D) K2SO4 is inert in this reaction. CuO(s) + H2SO4(aq) reacts because H2SO4 is able to provide H+ ions, which react with CuO to form CuSO4. On the other hand, K2SO4 does not give a product …
CuO(s) + H2SO4(aq) = H2O(l) + CuSO4(aq)
1 CuO(s) + 1 H 2 SO 4 (aq) = 1 H 2 O(l) + 1 CuSO 4 (aq) For each element, we check if the number of atoms is balanced on both sides of the equation. Cu is balanced: 1 atom in reagents and 1 atom in products. H is balanced: 2 atoms in reagents and 2 atoms in products. S is balanced: 1 atom in reagents and 1 atom in products.
