Question

Choose an example of electrolysis acid rain dissolving limestone powering a remote control with an alkaline dry cell iron rusting in salt water potassium metal reacting vigorously with water to generate hydrogen gas recharging a nickel-metal hydride battery

Answer 1

answer : iron rusting in salt water

explanation:

Water is the enabler of fast oxidation of iron so freshwater will also cause rust. However, salt water is a very good conductor (lots of dissociated ions) and so there are a number of electrolysis reactions that tremendously accelerate corrosion in salt water.
