Read the following statements and choose the set of correct statements:
(A) Chrome steel is used for cutting tools and crushing machines.
(B) The fine dust of aluminium is used in paints and lacquers.
(C) Copper is used for reduction of alcohol.
(D) Zinc dust is used as a reducing agent in the manufacture of paints.
(E) Iron is used for galvanising zinc.
Choose the most appropriate answer from the options given below:
Options
- A and (D) only
- B and (D) only
- C only
- D only
Correct answer
A. and (D) only
Step-by-step solution
Chrome steel is used for cutting tools and crushing machines while fine dust of aluminium is used in paints and lacquers.
Zinc dust is a reducing agent for manufacture of dye-stuffs and paints.
So, statements A, B and D are correct.
Copper is used for oxidation of primary and secondary alcohols into aldehydes and ketones respectively at high temperature. So, statement (C) is incorrect.
For galvanisation of iron, zinc is used to prevent iron from corrosion so, statement is also incorrect.
Hence, correct statements are (A), (B) and (D) only.
