Yes, it would corrode the iron.
Yes. For example, a teaspoon in a glass of water is a good liquid for cleaning off acid from car battery terminals.
NO!!! It is a white solid compound. Car batterty terminals may turn white, this is lead sulphate. It comes from a combination of lead from the lead plates in the battery and sulphuric acid, the battery liquid.
It's function is to provide a 'path' for electrons to flow between the positive and negative terminals. Without the acid, the plates attached to the terminals would simply be surrounded by air - which would not conduct electricity.
If battery acid is dropped on wood it will damage the wood.
Coating your car battery's positive and negative terminals with Vaseline will delay their natural inclination to corrode. It is a well known fact that sugar will corrode your teeth.
Sulfuric acid fumes escaping from the battery causes this corrosion.
The starter or battery cables/terminals are corrode.
on the battery
Most battery terminals are made of lead.
no
hydrogen gas being released from the acid in the battery. It mixes with other things in the atmosphere under the hood and produces the corrosion you see
There are a few possibilities: Low battery, either because the alternator isn't keeping the battery charged or the battery is old and has failed. Corroded battery terminals, usually an indicator that the battery is blowing acid fumes. Batteries usually don't last long after the terminals start to corrode. Faulty starter solenoid. IT SOUNDS LIKE IT COULD BE YOUR STARTED CYLINOID
yes it does because the car needs them to drive
take the battery terminals off and wire brush then and the terminals on the battery too to clean them and then re-hook.
Most of the time there a nuts on the battery terminals , you only have to loosen them up and pull on the terminals away from the battery, they should pop right off afterwards.
If terminals of the battery are reversed, it will short the device that is using the battery. On a car reversing the cables can blow fuses, melt wires, and fry computers.
