2. materials:
two nail,two cup,salt water,fresh water,
3. Hypothesis.I think that a nail rust faster in salt water because of the chemicals in the salt.
4. Procedure:
inde variable:same nail and fresh and salt water
dep variable:how many days will it take
con varable:size of nail,different water

Salt water will eat them up! Fresh water not so bad but if both are in direct contact with water then go to SS Screw. Now What type of wood are you using? They are not a good choice to be used with redwood, cedar, or treated lumber, because the acids and chemicals in these woods will eat away at the zinc coating.

yes, salt solution increases the conductivity of the water which increases the corrosion (rust) of the iron.
I put an iron nail in tap water and salt water and then purified water and salt water and both times the iron nail rusted faster in the tap and purified water versus the salt water.
Yes because the salt speeds up the electron transfer between the oxygen dissolved in the water and the iron nail therefore oxidising the nail faster
Zinc will corrode in vinegar faster than salt water
Salt water does make nails rust faster than non-salted water, because when salt is added to water, it will rust the top layer of the nail, and then make the nail basically shed its top layer. Then the salt will rust that layer, and this process continues until the whole nail is rusted. Normal water can only really rust the top layer, and can't get to the rest of the nail.
Yes, because the chemical reaction of rust is next to impossible to get the iron, water and oxygen back from the iron oxide it creates by rusting, and its like baking a cake is a chemical reaction, once the cake is a cake you can't get the eggs or sugar back. The rust also makes the nails weak and flimsy, this is why we shouldn't use nails if they are rusted, especially large structures. A way you can tell its a chemical reaction is that the color changes and the appearance changes.
I did an experiment on this in 4th grade. When I put iron nails in bleach, the nails turned a reddish hue at first, then faded to a brown. This is because of oxidation. The bleach stimulates the ions in the iron, causing them to swirl in a circular motion, thus creating the reddish brown color.
Like poles will repel.Unlike poles will attract.
Iron will rust more quickly in salt water than fresh freshwater. The salt in the water accelerates the corrosion process.
Zinc will corrode in vinegar faster than salt water
Because the ion chloride (Cl-) from salt is very corrosive.
Nails do not rust in water. Nails only rust in water if oxygen is present. This is because the iron in nails react with oxygen and water to form a compound called hydrated iron(III) oxide.
Any water makes iron rust. Rust is iron oxide. It happens when water allows the oxygen to dissolve in it and get to the surface of the metal. Salt water has dissolve salts in it which makes it work faster.
Of course water, due to its high polarity Carbon dioxide and baking powder easily dissolve in it and then the attack of these compounds on iron nails becomes easier.
Water from the tap or drinknig fountain will rust iron,
It will rust faster in a salt water base and it will also rust faster in a tap water base not a sugary or a pop type, they have a slower fashion of rusting.
a nail that is made from steel
iron nails are nails made up of iron
Rusting of iron needs the presence of water.
Salt water contains Na+ & Cl- ions which are highly reactive with iron to form FeCl2 .So iron rust faster in salt water.
