Question

1.name three different types of iron produced in the factories.

2.what is the difference between concentrated and dilute sulphuric acid?

Answer 1

Part-1
Types of iron -
1. Pig Iron (Steel making)
2. White Cast Iron (in lubrication )
3. Malleable Iron ( in pipes production)
4. Grey cast iron (in ball mills)
5. Ductile Iron (in truks production)

Part- 2
Dilute sulphuric acid is different from concentrated sulphuric solution. Dilute sulphuric acid has higher amount of water with less concentration of sulphuric acid (solute(less) +solvent) whereas concentrated solution or acid has more amount of sulphuric acid and very less amount of water . Thus a pure concentrated acid react strongly with any compound to allow reactant to react effectively.
