Experiment 5 In the first part of this lab‚ the objective was to get the molar concentration of sodium hydroxide by using the secondary standard‚ sodium hydroxide solution with the primary standard‚ potassium hydrogen phthalate. With this information‚ we could create a second derivative plot‚ which can be used to obtain the exact concentration of the secondary standard‚ sodium hydroxide. Also‚ the indicator can give us these results along with the end points and with the readings from the pH meter;

Preparation and melting point of Aspirin Aspirin is a painkilling drug and is produced worldwide to reduce and stop pain. Aspirin is made up of ehtanoylation of 2-hydroxbenzenecarboxylic acid in a presence of phosphoric acid. AIM: The aim of the experiment is to prepare and produce aspirin as pure as possible. I will do this threw preparing the aspirin and purifying the product threw recrystallization. I will then obtain a melting point of my product to get an estimate of its purity. By the end

Whiten Teeth with Banana Peel The versatility of banana itself and its peel goes a long way. Aside from the fact that banana is full of vitamins and minerals‚ and is used in beauty regimen‚ its peel is also utilized in so many ways; from skin care regimen‚ to fertilizer and now to whiten teeth. Using banana peel as teeth whitening is considered extremely safe and healthy because it is not only the flesh of the banana that contains vitamins and minerals but the peel as well. Banana peel has no coarseness
