Three things that you observe in a chemical change of mixture Mg-CuSO4?
Formation of a new substance: When magnesium reacts with copper sulfate, the blue color of copper sulfate fades as copper metal is formed, indicating a chemical change has occurred. Release of gas: In this reaction, bubbles of gas may be observed, which could be hydrogen gas being evolved as magnesium displaces copper from copper sulfate. Temperature change: The reaction between magnesium and copper sulfate is exothermic, meaning it releases heat. The mixture may feel warm or hot to touch during the reaction, indicating a temperature change has taken place.
Is magnesium burning a physical change?
No, magnesium burning is a chemical change because the magnesium undergoes a chemical reaction with oxygen to form magnesium oxide. Physical changes do not alter the chemical composition of a substance, whereas chemical changes do.
Is burning a strip of magnesium ribbon a chemical or physical change?
Burning a strip of magnesium ribbon is a chemical change because the magnesium reacts with oxygen in the air to form magnesium oxide. This reaction results in the formation of new substances with different properties than the original magnesium ribbon.
Is copper sulphate a physical change or chemical?
Copper sulfate dissolving in water is a physical change as no new substance is formed. However, if copper sulfate is heated to decomposition, it would be a chemical change because a new substance is formed.
Copper sulfate and sodium carbonate physical or chemical change?
When copper sulfate and sodium carbonate are mixed together, a chemical reaction occurs. This reaction forms copper carbonate, a new substance with different properties than the reactants. Therefore, the mixing of copper sulfate and sodium carbonate is a chemical change.
Is magnesium sulfate in water a physical or chemical change?
When magnesium sulfate dissolves in water, it undergoes a physical change, not a chemical change. The molecules of magnesium sulfate are simply dispersed in the water, but no new chemical substances are formed.
When copper sulfate mixed with sodium hydroxide is a form of physical change or chemical change?
The reaction between copper sulfate and sodium hydroxide is a chemical change, as new substances are formed with different chemical properties from the original substances. The blue copper sulfate solution reacts with the colorless sodium hydroxide solution to form a blue precipitate of copper hydroxide and sodium sulfate solution.
Is magnesium sulphate with water physical or chemical process?
The dissolution of magnesium sulfate in water is a physical process. When magnesium sulfate (MgSO₄) is added to water, it separates into its constituent ions (Mg²⁺ and SO₄²⁻) but does not undergo a chemical change; the chemical identity of the compound remains unchanged. The process is reversible, as the ions can recombine to form solid magnesium sulfate upon evaporation of the water.
How does dissolving magnesium in a solution affect its chemical properties and reactivity?
Dissolving magnesium in a solution can change its chemical properties and reactivity. The magnesium atoms become ions in the solution, which can react more easily with other substances. This can lead to new chemical reactions and potentially alter the behavior of the magnesium in the solution.
In chemistry experiment a student by mistake put some magnesium strip in blue coloured copper sulphate solution what change will he observ in colour of the solution.write the reaction also?
When a magnesium strip is added to a blue copper sulfate solution, a chemical reaction occurs, resulting in the displacement of copper by magnesium. The solution will change from blue to colorless as the copper ions are reduced to solid copper, which precipitates out of the solution. The balanced chemical reaction for this process is: [ \text{Mg (s)} + \text{CuSO}_4 \text{(aq)} \rightarrow \text{MgSO}_4 \text{(aq)} + \text{Cu (s)} ] This shows magnesium displacing copper from copper sulfate.
Is adding water to heated copper sulfate crystals chemical or physical?
Adding water to heated copper sulfate crystals is a chemical change. When water is added to heated copper sulfate crystals, the copper sulfate undergoes a chemical reaction where it dissolves in the water to form a solution. This is a chemical change because the chemical composition of the copper sulfate is altered during the process.
What happens when copper sulfate and magnesium react?
When copper sulfate and magnesium react, a displacement reaction occurs where the magnesium displaces the copper in the solution to form magnesium sulfate and copper. The magnesium will appear to dissolve and bubbles of hydrogen gas will be released during the reaction.
What is the chemical reaction between Epsom salt and water?
When Epsom salt (magnesium sulfate) is dissolved in water, it dissociates into magnesium ions (Mg2+) and sulfate ions (SO4 2-). This dissociation process is a physical change, not a chemical reaction, as the chemical composition of Epsom salt remains the same.
When water is added to a blue solution of copper sulfate the solution changes to a lighter shade of blue Is this an example of a chemical reaction?
If the water being added is pure, and the solvent in the copper sulfate solution was water, then no, this should not result in a chemical reaction. The visual change is due to dilution of the solute

Is Heating a hydrous salt to obtain an anhydrous salt a chemical or physical change?
if you mean epsom salts (magnesium sulfate) then heating it will result in a decomposition reaction, where magnesium oxide (s) and sulfur trioxide (g) is formed. The decomposition reaction is therefore a chemical change.
What happens when you add zinc to magnesium sulphate?
You create magnesium sulfate and zinc through single discplacement/replacement.Zinc sulfate(aq) + Magnesium (s)->Magnesium sulfate + Zinc (s)ZnSO4(aq)+ Mg (s) -> MgSO4 + Zn(s)Hope it helps ;)
