What else can I help you with?
Is soluble iron present in this solution?
Yes, soluble iron is present in this solution.
Why iron does not displace sodium from salt solution?
Iron does not displace sodium from a salt solution because it is not reactive enough. Iron does, however, displace Cu from a copper sulphate solution.
Why copper cannot replace iron from its salt solution?
Copper is less reactive than iron, so it cannot displace iron from its salt solution in a single displacement reaction. Iron is higher in the reactivity series than copper, so iron can displace copper from its salt solution.
How is metallic hydroxide formed when an iron is immersed in an acidic solution?
After the reaction of iron with an acid a salt is formed, not a hydroxide.
What elements are present in salt and Iron filings?
Sodium, chlorine and iron.
How metallic hydroxide is formed when an iron is immersed in an acidic solution?
After the reaction of iron with an acid a salt is formed, not a hydroxide.
Is salt solution an acid or alkali?
A salt solution is usually neutral, meaning it is neither an acid nor an alkali. The pH of the solution will depend on the specific salt present and its reaction with water.
Can you separate the salt and iron fillings?
Yes. You can add water to dissolve the salt (the iron will not dissolve). Then pour off the solution, leaving the iron filings behind. If you want to now retrieve the salt, you can just evaporate the water.
What is the function of the phenanthroline solution that is added to the unknown iron solution?
Phenanthroline solution is added to unknown iron solution to form a red-colored complex with iron ions. This complex is then used for colorimetric analysis to determine the concentration of iron present in the solution.
How can a salt solution be obtained from what is left in the dish?
To obtain a salt solution from what is left in a dish, add water to the dish and stir to dissolve the remaining salt. Filtering the solution can help separate any solid particles from the salt solution. You can then collect the filtered salt solution for use.
What happens to iron powder and salt mixture when it is added to water?
When iron powder and salt are added to water, the iron powder will react with the water to produce iron oxide (rust), hydrogen gas, and heat. The salt will dissolve in the water. This reaction is a chemical change, resulting in a mixture of iron oxide, hydrogen gas, salt solution, and any unreacted iron powder.
How metallic hydroxide is formed when iron is immersed in an acidic solution?
After the reaction of iron with an acid a salt is formed, not a hydroxide.
