Most metal oxides react with dilute acids.The reaction between an insoluble metal oxide and a dilute acid is often quite slow so it is possible to observe the progress of the reaction as the solid reactant disappears as a soluble product is formed. Hence to enhance the speed of the reaction, excess Copper Oxide is used in preparing Sulphate Salt.

What happens when sulphuric acid is mixed with copper oxide and heated?

When sulfuric acid is mixed with copper oxide and heated, a chemical reaction occurs. The copper oxide reacts with the sulfuric acid to form copper sulfate and water. The reaction is exothermic, meaning it releases heat.


What happens when dilute sulphuric acid is poured on copper plate?

When dilute sulfuric acid is poured on a copper plate, a chemical reaction occurs where the sulfuric acid reacts with the copper to form copper sulfate, water, and sulfur dioxide gas. This reaction will cause the copper plate to dissolve and create a blue-green solution of copper sulfate. Heat and bubbles may also be observed as the reaction takes place.


What happens when you heat copper in oxygen?

When you heat copper oxide and magnesium why do you get grey powder?

You get a grey powder because magnesium is higher up in the reactivity series than Copper - (magnesium is more reactive than copper) therefore when you heat it up there is a displacement reaction. That grey powder is actully magnesium oxide and copper e.g Copper oxide + magnesium = magnesium oxide and copper.


What gas do you get when you heat sulfuric acid?

Heating sulfuric acid will release sulfur trioxide gas (SO3).


Can you melt a broken drill bit in aluminum using sulfuric acid?

Sulfuric acid does not melt metal, it oxidizes it and dissolves it. Aluminum will react with sulfuric acid, but because of the protective coating of aluminum oxide the reaction is extremely slow.


Which planet with an atmosghere that rains sulfuric acid?

Venus is the planet with an atmosphere that rains sulfuric acid. The intense heat and pressure on Venus cause sulfuric acid to form in the atmosphere and fall as acid rain.


Is dilution of sulfuric acid endothermic or exothermic?

The dilution of sulfuric acid is exothermic because it releases heat.


What happens when dilute sulphuric acid is poured on a copper plate-?

It depends, if the susexphuri acid is of a high concentration and is hot, then the copper plate will react and dissolve. sex though it is not a strongly oxidizing acid, hot concentrated sulfuric acid is a strong enough oxidizing agent to dissolve copper.


What is the specific heat of 20% sulphuric acid solution?

The specific heat capacity of a 20% sulfuric acid (H₂SO₄) solution can be estimated based on the specific heat capacities of its components (water and sulfuric acid) and their respective proportions in the solution. Here’s a step-by-step approach to estimate it: **Components in the Solution**: Sulfuric acid (H₂SO₄) Water (H₂O) **Specific Heat Capacities**: The specific heat capacity of water (H₂O) is approximately 4.186 J/g°C. The specific heat capacity of concentrated sulfuric acid (H₂SO₄) is around 1.38 J/g°C. **Calculation Method**: A 20% sulfuric acid solution means that for every 100 g of solution, there are 20 g of sulfuric acid and 80 g of water. **Estimation**: To estimate the specific heat capacity of the solution, you can use a weighted average based on the proportions of water and sulfuric acid: [ \text{Specific heat of solution} = (\text{% of water} \times \text{Specific heat of water}) + (\text{% of sulfuric acid} \times \text{Specific heat of sulfuric acid}) ] Given that 20% of the solution is sulfuric acid and 80% is water: [ \text{Specific heat of 20% sulfuric acid solution} = (0.80 \times 4.186) + (0.20 \times 1.38) ] Calculate the specific heat: [ \text{Specific heat of 20% sulfuric acid solution} = (3.3488) + (0.276) ] [ \text{Specific heat of 20% sulfuric acid solution} \approx 3.624 \text{ J/g°C} ] Therefore, the specific heat capacity of a 20% sulfuric acid solution is approximately **3.624 J/g°C**. This estimation assumes ideal mixing and that the specific heat capacities of water and sulfuric acid are accurate for dilute solutions around this concentration.
