Q. Can iron sulphate solution be stored in Aluminium?
1 Answer. Aluminium is more reactive than iron. Aluminium from the walls can react with ferrous sulphate to form its sulphate and iron is precipitated.
Q. What happens when Al is added to FESO4?
The reaction of can be written as: Here Al displaces Fe from the solution hence Fe will deposit and color of solution will change to reddish brown. Hence when we mix aluminum react with iron sulphate, it forms aluminum sulphate and iron will deposit.
Q. When Aluminium metal is added to ferrous sulphate solution the correct observation is?
Explanation: When the student added the piece of aluminium metal to the solution of ferrous sulfate, the color of solution will get decolorized from blue to colorless.
Q. How do you store iron sulphate solution?
Ferrous Sulfate Safe Storage and Handling
- Store and label all chemical products in accordance with the instructions on the safety sheet.
- Do not store chemicals together with inflammable material and gas cylinders.
- Store chemical containers with closed lids when they are not in use.
Q. Why cuso4 Cannot be stored in iron?
Copper has a reduction potential of +0.34 V. Iron has a reduction potential of -0.44 V. So, the iron has lower reduction potential, it will be more reactive than iron. Hence, we cannot store copper sulfate in an iron vessel.
Q. Can we store feso4 in iron vessel?
For this system we have to find out whether the reaction is spontaneous or not. If the reaction come out to be spontaneous then we can’t store it or vice versa. If = -ve then Non spontaneous. Since Eocell = -ve therefore the given reaction is non spontaneous and hence the FeSO4 can be store in nickel vessel.
Q. Can we store cuso4 solution in iron container?
Thus, copper sulphate solution is not stored in the iron container.
Q. Can we store feso4 in Cu vessel?
No, because iron is more reactive than copper, therefore reaction will take place.
Q. Can we protect aqua solution of ferrous sulphate in copper vessel?
yaa we can easily store it becoz copper is unreactive than iron and can’t displace iron acc to to the reactivity series.
Q. What will be the Colour of copper sulphate after heating?
On heating, the colour of copper sulphate crystals changes from blue to white.
Q. What is the Colour of Aluminium sulphate solution?
colorless
Q. What happens when Aluminium reacts with potassium hydroxide?
Hydrogen is evolved. Hint: The reaction of aluminium in KOH is an example of a redox reaction. The Aluminium metal is oxidized to aluminium ion with an oxidation number of +3 and the hydrogen in KOH is reduced from an oxidation number of +1 to zero by releasing hydrogen gas.
Q. What is Aluminium sulphate used for?
Aluminium sulfate is a chemical compound with the formula Al2(SO4)3. It is soluble in water and is mainly used as a coagulating agent (promoting particle collision by neutralizing charge) in the purification of drinking water and wastewater treatment plants, and also in paper manufacturing.
Q. Is Aluminium sulphate acidic or basic?
Because aluminum sulfate is extremely acidic, it’s sometimes added to very alkaline soils to balance the pH for plants. When aluminum sulfate comes into contact with water, it forms aluminum hydroxide and a much diluted sulfuric acid solution, which alters the soil acidity.
Q. What pH is alum?
Alum is most commonly delivered as a liquid concentration, having a solids level of 8.3% as Al2O3 or about 50% as hydrate. Alum solutions are acidic. For instance, a 1% solution has a pH of around 3. Ionic species present in alum solutions are highly dependent on the degree of reaction with hydroxyl ions.
