Redox Titration Analysis of a Commercial Bleach A. Purpose ! ! ! To review oxidation-reduction reactions and their stoichiometry. To learn the concept and technique of redox titration. To determine the percent (m/v) of an active ingredient‚ sodium hypochlorite (NaOCl)‚ in a commercial bleaching agent. B. Theoretical Background Whereas acid-base reactions involve the transfer of a proton‚ oxidation-reduction or redox reactions involve the transfer of electrons from one substance to

Cleaning Seashells: 1. Burying - This one is pretty simple. Find an area in your yard where you don’t mind digging a hole and bury the shells about 18" down. The reason for the depth is so animals will not find them and dig them up. Also you or your neighbors won’t smell them. Let them remain buried until the insects‚ ants‚ larvae‚ worms and bacteria remove all the tissue and they will darn near polish the inside of the shell. But‚ this could take as long as a couple of months. The longer you

Purpose: In this experiment‚ the purpose was to have found out how different chemical solutions help or harm radish plant growth when the seeds of the radish plant are soaked in said solutions prior to planting. Background: The IRP project I am doing is based off the subject of seed germination. The seeds I will be planting are cherry belle radish seeds‚ freshly bought. Instead of planting the seeds in soil like it is normally done‚ the plant seeds will be placed on paper towels to grow for better

acetic acid and oxidized with sodium hypochlorite to make crude camphor. The crude camphor was purified by sublimation. The final product was characterized by obtaining a melting point and inferred spectroscopy. The experiment was carried out to see if bleach could oxidize borneol and if it is greener than using a Jones reagent. Sure enough camphor was made with a 4.03 g of unsublimed camphor and 0.08g of pure camphor with a 2 % yield (in moles). No melting point or IR peaks were obtained. However‚ the

Rolling Stone would say “One of the greatest albums of all time” (Greene). The album’s name comes from combining the otherwise separate English words never and mind. “Nevermind” was different from Nirvana’s first album “Bleach” because it was heavier and more alternative sounding than “Bleach” which had a pop music style of sound. Alternative music is a subgenre of rock music that uses more experimental styles and chord progressions. “Nevermind”

It all started when I let a stylist cover my hair in 40 volume bleach. “Let” is the wrong word‚ I was 15‚ in the suburbs of Philadelphia‚ and essentially knew nothing. All i knew was that i wanted to be BLONDER—similar to what my hair looked like when I was about 4 years old. It had been the hay day of emo kids‚ and when my natural golden locks weren’t really doing anything to help my Myspace photos‚ I had decided to add red highlights‚ then chopped it‚ then blonde highlights with an under-layer

Oxidation of Cyclohexanol Introduction: The oxidation of cyclohexanol involves using household bleach to oxidize this secondary alcohol and produce a ketone product‚ cyclohexanone. Oxidation-reduction (redox) reactions occur when the oxidation state of atoms change due to a transfer of electrons. Oxidation occurs when electrons are ‘lost’ to the formation of bonds and reduction occurs when electrons are ‘gained’ in the braking of bonds (Levine). Using this reaction and its product‚ a redox experiment

was founded in 1913 by five California businessmen. For the first forty-five years‚ the company avoided expanding its product line and solely sold their standard Clorox liquid bleach. In the 1950s Clorox‚ still a one-product company‚ possessed the largest portion of the market for consumer bleach. This domination of bleach caused the Procter & Gamble Company to view Clorox as a befitting addition to its existing line of products and attempted to acquire the company. The Federal Trade Commission challenged
