Effect of Sodium Chloride on Rust

Corrosion is the breaking down or destruction of a material, especially a metal, through chemical reactions. the most common form of corrosion is rust which occurs when iron combines with oxygen and water.”(Dictionary.com, 2018) “like pure iron, corrode quickly. Stainless steel, however, which combines iron and other alloys, is slower to corrode and is therefore …

An Examination Of The 1,2-Diphenyl-1,2-Ethanediol Synthesis Through The Reduction Of Benzoin In Sodium Borohydride

To carry out the sodium borohydride reduction, 1.0g benzoin previously synthesized was combined in a 125mL Erlenmeyer flask with 15mL 100% ethanol and 250mg sodium borohydride. The flask was stirred on a magnetic stir plate for 15min. After 15 minutes, a thin-layer chromatography (TLC) analysis was performed to check for reaction completeness. The TLC developing …

An Experiment On Water’s Surface Tension In Different Sodium Chloride Concentration

Surface Tension Abstract: To determine the surface tension of water with different concentrations of sodium chloride, capillary rise was examined. This was done by examining the height a liquid rose in a capillary depending on the concentration. The liquid was but in an apparatus containing the capillary, and the system was disrupted and the let …
