In fact they are so certain of this that they question why we’re even bothering to do this experiment. The wires were cleaned by scrap- ing the surface carefully with a fine abrasive paper. At the end of my experiment my hypothesis was correct because the nail in the saltwater was the first to rust. Try boiling the water… does this make the nail rust faster, slower or is there no impact on the rusting time? The problem you'll be attempting to solve in this science fair project is which metals corrode the fastest, and under which conditions. Carl H. wrote:My hypothesis was that if one penny was placed in tap water and one in salt water, the penny in the salt water would corrode quicker than the one in fresh water. Preparation of the Metals Either copper or iron metal was in the form of a wire with a diameter of 0.2 mm, cut into 2.0 m lengths. Salt and other substances put down to deal with icy roads greatly increase the rate at which rust forms on buildings, vehicles and other structures. Materials: 4 iron nails, 1 steel nail, a piece of copper/brass, 5 test tubes, cotton wool, solid calcium chloride, magnesium ribbon. Salt water will cause corrosion faster because the salt will act as a catalyst steel up the change and erode the materials. In the experiment you just wait and record which nail rusts faster. After 7 days, the one in fresh water started to turn green, but the salt water penny got shiny and clean. I learned that when a nail rusts it gains weight. The orange juice was a good choice of solutions because acids … Join now. Then the wires were anodized for 30 minutes in … Ask Your Question Fast! Question Date: 2015-01-31. Log in.

The … So you need lots of lovely ions, that's the key - … The project is about whether iron will rust faster in salt water than fresh water, so data collection means collecting any evidence that it does or doesn't. Rusting of iron refers to the formation of rust, a mixture of iron oxides, on the surface of iron objects or structures. Fe (OH)3 is rust that forms under water. I feel it would corrode all of the metals. You'll test five metals-silver, steel, zinc, copper, and aluminum-to see which corrodes fastest in water and in salt water. It literally takes a really long time for copper to rust. Community Experts online right now. It forms when iron and oxygen react in water or in moisture in the air. Answer: The corrosion of iron indicates a chemical change in the metal. The following experiment investigates the conditions necessary for rusting to occur. Cleaning & Laundry. the first being pure distilled water, then a series with 2 tsp, 4 tsp, and 8 tsp of salt in 4 oz of water. Rust is the reddish brown compound called iron oxide that forms when iron an oxygen react in the presence of water and air, hence the term oxidation. Further, the role of salt is to provide an electrolyte which makes it so that the "oxidation and reduction" reactions - the REDOX reactions - involved in this process occur more easily. In third … Secondary School. Lets take as a given that rust is iron oxide. Water is the enabler of fast oxidation of iron so freshwater will also cause rust. saltwater and fresh water both contain oxygen, the iron nail will rust faster in saltwater because it contains more oxygen. kept constant using ice-salt water bath.
