Which Road Deicer Corrodes Steel the Most?

Aside from the cups that leaked, the low cost deicers (potassium chloride and sodium chloride) caused the most corrosion while the high cost deicer (potassium acetate) caused the least corrosion. This was consistent with my hypothesis. The leaked cups caused the most corrosion because of the higher oxygen exposure. A quantitative 250 sample corrosion experiment was conducted to discover which deicers corrode steel the most and least of the ........>>>>Read More


To Study the Effect of Metal Coupling on the Rate of Corrosions

Corrosion is the gradual destruction of material, usually metals, by chemical reaction with its environment. In the most common use of the word, this means electrochemical oxidation of metals in reaction with an oxidant such as oxygen. Rusting, the formation of ironoxides, is a well-known example of electrochemical corrosion. This type of damage typically produces oxide(s) or salt(s) of the........>>>>Read More

Study of Diffusion of Solids in Liquids

When substances are brought in contact with each other they intermix, this property is known as Diffusion. This property of diffusion takes place very rapidly in case of gases and to a lesser extent in case of liquids, whereas solids do not show this process of diffusion with each other. But what we can observe in case of solids is that the diffusion of solids in liquids takes place at a very slow rate.........>>>>Read More

Fuel Go Boom

To measure the energy output during the combustion of biodiesel- petrodiesel fuel blends To determine which fuel/fuel blend will optimize energy output. The hypothesis of the experiment was correct. As the percentage of biodiesel increased in a biodiesel-petrodiesel fuel blend, the energy output increased in a somewhat proportional manner. This helps to demonstrate the feasibility of biodiesel as a mass-produced alternative fuel. In order to better model this relationship, a greater variety of fuel blends should have been used........>>>>Read More


Get More Hydrogen from Your Water

Electrolysis must have an electrolyte in order to work. But what factors affect an electrolyte's effectiveness? My hypothesis is that it is either the pH of the solution or the ion concentration. The following electrolytes were used: sodium chloride, potassium chloride, sodium bicarbonate, sodium hydroxide, hydrogen peroxide, and isopropyl alcohol. During each trial, I measured the pH of the solution, the temperature of the water, and the mL of gas produced in 5 minutes with a 9-volt charge. ........>>>>Read More


To Prepare a Smoke Bomb

A smoke bomb is a firework designed to produce smoke upon ignition. Smoke bombs are useful to military units, self-defense and pranks.The smoke bomb was first created in 1848, by the inventor Robert Yale. He developed 17th century Chinese-style fireworks and later modified the formula to produce more smoke for a longer period of time. Coloured smoke devices use a formula that consists of an oxidizer (typically potassium chlorate, KClO3), a fuel (generally sugar), a moderant (such as sodium bicarbonate) to keep the reaction ........>>>>Read More


Study of Content of Ascorbic Acid in Citrus Fruits

Vitamin C or ascorbic acid in citrus fruits is a water soluble carbohydrate like substance involved in certain metabolic processes of animals.
