Bureau Veritas QC Inspector Interview Questions and Answers

Q1. How to prepare 0.1 n hcl?
Add your answer
Q2. What is anode and cathod
Ans. 
Anode and cathode are electrodes used in electrochemical cells to facilitate the flow of electrons.
• Anode is the electrode where oxidation occurs and electrons are lost.

• Cathode is the electrode where reduction occurs and electrons are gained.

• In a battery, the anode is the negative terminal and the cathode is the positive terminal.

• In an electrolytic cell, the anode is the positive terminal and the cathode is the negative...read more

Q3. What are haviour among h20 and hcl
Ans. 
H2O and HCl exhibit different behaviors due to their chemical properties.
• H2O is a polar molecule, while HCl is a polar covalent molecule.

• H2O has a higher boiling point and melting point than HCl.

• HCl is a strong acid, while H2O is a neutral molecule.

• H2O can act as a solvent for many substances, while HCl is mainly used in chemical reactions.

• H2O has a higher density than HCl.

Q4. Difference between SS316L and SS316
Ans. 
SS316L has lower carbon content than SS316, making it more corrosion resistant and suitable for welding applications.
• SS316L has lower carbon content (0.03% max) compared to SS316 (0.08% max)

• SS316L is more corrosion resistant due to the lower carbon content

• SS316L is commonly used in welding applications where post-weld annealing is not possible

• SS316 is more commonly used in applications where higher strength is required
