7.What effect does water pH have on the rusting of nails?
If you're speaking about nails as in "hammer & nails" then the effect of water and oxygen will eventually corrode them by rusting.
Rusting requires iron, oxygen and water. Some substances added to water can accelerate rusting, but these are usually ionic. Sugar, being molecular, would have no effect.
The fat present in milk becomes deposited on nails and it is water repellent.
Rusting of iron needs the presence of water.
Water boiling is a physical process; also dissolving. Rusting is a chemical process (oxidation).
all of them
it is caused by a chemical reaction with the metal and the substance. There are many experiments you can do to prove this
All nails not made of galvanized metals or aluminum rust because the wet nails become oxidized then rust forms. Painted nails cannot escape the rusting processes if the paint does not get into every nook and cranny of the nail. Some paint has so much water in its formula the paint itself will rust as the water and air combine. Here is an experiment for you. Drop a nail into a completely filled jar of water then screw down the jar lid. Take another jar and put the nail into it with only half filled and leave the lid off. Which one rusts faster? Construction crews will put caulking around exposed nails to prevent the water and air from rusting the nails.
I am not sure what your project consists of. The only result of iron rusting is that metallic iron becomes the compound iron oxide. You might want to examine the role of salt as a catalyst for rusting. Prepare, let us say, four glasses. Put a nail in each. The first glass can be dry. The second can have pure water. The third can have mildly salty water. The fourth can have very salty water. You can then compare the rate at which the nails rust, in all four glasses.
The rusting of a nail is a spontaneous, although slow, reaction. The iron in the nail reacts with water in the atmosphere or water that has condensed or falled onto it to produce ferric oxide, which is rust.

Iron reacts to water through the slower process of oxidation, or rusting. The temperature of the water has little effect in speeding or slowing the process.
