Science behind corrosion-test
Corrosion is defined as an activity that transforms refined metals into more chemically stable forms such as oxide, hydroxide, carbonate, or sulfide. It refers to the slow decomposition of things (typically metals); thanks to chemical and/or electrochemical reactions with their surroundings. Corrosion engineering is the science of preventing and controlling corrosion.

Balance the following redox reaction in acidic solution.
Interpretation-
To balance the redox reaction in acidic medium.
Step 1-
Writing half reactions
Oxidation half reaction Re3+ ReO4-
Reduction half reaction BiO3- Bi2+
Step 2-
Balancing atoms other than O and H
Re3+ ReO4-
BiO3- Bi2+
Bi and Re are already balanced.
Step 3-
Balancing O by using H2O
4 H2O + Re3+ ReO4-
BiO3- Bi2+ + 3 H2O
Step by step
Solved in 8 steps
