Sodium thiopental

CAUTION: It is best not to get dichloromethane on your skin. Gloves are to be worn during this experiment, if improper safety precautions are taken there is a possibility of irritation, and or burning of the skin. CAUTION: Gas will build up in the separatory funnel while you are shaking it, so you must vent the funnel occasionally to prevent the stopper from popping out, causing a mess and possibly getting dichloromethane on your skin. ~During the pre-phase of this experiment it is…

Silver has an atomic mass of 107.9g whereas sodium has an atomic mass of 22.99g. The mass plays an important role in the value of chlorine because the mass precipitate value is used to determine the amount of chlorine moles in the precipitate. If the overall precipitate weighs less, there will be…

polarity of the said compound, although the conjugate acid of benzocaine formed as a result. Due to the change in polarity, the state of benzocaine shifted from being solubilized in diethyl ether to water. Through vacuum filtration, water was removed. Sodium hydroxide was added to the separated water in order to produce…

Truc-Nhi Do Separation of a Mixture The purpose of this lab was to separate a mixture, calculate the percent composition by mass, and find percent error. I first started out by taking the mass of each component of the lab. I used the infiltration method to allow the salt and water solution, a blended mixture, to pass through the filtration paper and into the beaker. A trick to know if something is a solution is to see is it has the aqueous sign (aq) in the formula, like NaCl(aq). This step…

Different batch experiments were conducted to access the effect of pH on removal of heavy metals by T1B1 strain. 100 ml of sterilized SE medium was inoculated into 250 ml Erlenmeyer flask containing 100 µl (107cells/ml) of bacterial suspension with HM (mg L-1): Fe (150), Mn (100), Ni (50), Cd (30), Cu (30) and Zn (50) with pH adjusted to 4, 6.5 and 9. Another set of experiments were set up by inoculating SE medium containing HMs (mg L-1 ): Cr+6 (100, 150, 200), Fe (100, 150, 200), Ni (50, 100,…

implemented an experimental design by having the amount of sodium polyacrylate inside our superabsorbent pillow be our independent variable. We chose this variable as our treatments because the goal of our experiment was to test how the amount of…

hydrochloric acid and heat the flame until it glows. Pour about 10 milliliters of 10% sodium chloride solutions into a small beaker and for unknown use 2mL of unknown solution instead of sodium chloride. Dip the clean wire loop into sodium chloride solution and place the loop in the flame and record the observation. Third, potassium flame will be tested. First, clean the wire lop with concentrated HCI for sodium flame test. Pour two milliliters of 10% potassium chloride solution into a small…

Slime was first created in 1976 by mattel ( A toy company) it was sold in little green trash cans. It was not stretchy or soft it didn't settle, or react to touch. The original slime was not made with pva or borate it was made with guar gum and didn't have an appealing texture. Slime is now sold across the world in shops online the main seller is Etsy but other slime sellers branch out and create their own websites. Like for example GlitterSlimes (Nicolette) started on Etsy and made her own…

The hypothesis was rejected after the testing due to certain chemicals not performing what was standardized and predicted by the hypothesis. According to the overall averages, the number one most effective was Betadine with an average of 36.33mm, Hand soap was second, third was Lysol, Isopropyl alcohol scored fourth, fifth place was Germ X, and seventh had the smallest average of 7mm which was Neosporin.Betadine was expected to have a high score due to its popularity in treating wounds but the…
