Potassium permanganate

All the materials were purchased from Sigma-Aldrich and used as received unless otherwise stated. Reaction (1) How to make Sodium Azo-Tetrazolate--Pentahydrate (SAT) Approximately 2.15 g of Aminotetrazolate monohydrate was added to approximately 62.5 ml of 2 M sodium hydroxide. While being stirred, the solution was heated, increasing its temperature up 10 degrees Celsius, up to 60 degrees Celsius. Over a one hour time period, potassium permanganate (an amount of 2.5 g) was added in increments. After this, sodium sulfite was added at a slow pace, and powerful stirring destroyed the remaining permanganate. To determine the endpoint of the addition of sulfite, a color change to a yellow…

Potassium Permanganate Test: 1. Three drops of the compound to be tested are dissolved in 2 ml of water or aqueous ethanol. 2% KMnO4 solution (a purple solution) is added drop wise and the solution is shaken. 2. The purple color of the KMnO4 solution disappears and a precipitate of MnO2 is formed. A negative test is if there no precipitate. 3. Repeat for every unknown and record observations. Observations and Results Water Solubility Test: When the test was conducted and observations were made,…

DISCUSSION There are three chemical properties will be discussed which are combustion, reaction with bromine and reaction with potassium permanganate. Combustion was used to test the unsaturation of hydrocarbon. The degree of unsaturation refers to the number of the rings and / or multiple bonds present in the hydrocarbon molecule (McMurry, 2015). Hexane was a saturated hydrocarbon, it completely combusted and emitted carbon dioxide plus water. Cyclohexene was an unsaturated hydrocarbon, it…

In experiment 1.1, we studied the relationship molecule size has with diffusion rate. Our hypothesis claimed that smaller molecules will travel farther across the agar plate given the same duration of time. Based on the data collected, our hypothesis was proven true. Potassium permanganate has a molar mass of 158 g/mol, methylene blue 319.85 g/mol, and potassium dichromate with 294.185 g/mol. Potassium permanganate diffused the farthest, potassium dichromate second, and methylene blue secured…

This paper will discuss the management practices that can be implicated to help control the severity of Hyperkalemic Periodic Paralysis in affected horses. Because of the debilitating effects that this condition has, it is important to examine the ways that this disorder can be controlled. Low potassium diets, regular turnout, and a constant schedule have been shown to effectively manage the condition of Hyperkalemic Periodic Paralysis. The role of potassium in action potentials, as well as in…

K2CrO4 was added in Step 12 and this was what indicated whether or not the sample from Part B contained barium or not. The chloride ion in potassium chromate bound to the barium cation and formed a precipitate, if there were any calcium cations present, they would have stayed in the liquid solution. If the substance in Step 12 remained cloudy, it would have been a sign for a false positive. This refers to a result that may not be correct, and if it were the case, a precipitate of barium may have…

The instructor brought forth three sea urchins from the tank in the back of the room. The three sea urchins were then injected with .5M of potassium chloride (KCl) and placed mouth up into a 120 mL of seawater. After waiting for 10 to 15 minute time interval there was no reaction from the sea urchins. The lab instructor injected another .5M of potassium chloride (KCl) and placed into 120 mL of sea water mouth up. Once all three were placed into containers with the seawater solution they…

Know One Drug Erin Wu I chose losartan. For your molecule: Note the primary indication, and a secondary indication (even if off label) The primary indication is hypertension. It is also used for diabetic neuropathy and hypertension with left ventricular hypertrophy. Note and be able to draw the pharmacophore that appears to be responsible for activity. Losartan1 valsartan2 The molecule on the left is losartan and the…

from chronic ketosis can be drawn on to synthesize ATP during periods of metabolic stress, such as during a seizure. Typically, when an excitatory action potential is fired in a neuron, ion channels open that allow for the flow of sodium ions to flow down its electrochemical gradient into the neuron, resulting in depolarization. For the neuron to return to its resting potential, sodium potassium pumps located in the neuronal membrane pump three positively charged sodium ions out of the neuron…

amounts of water to determine the minimum amount needed to completely dissolve the salt. The cation test told whether the unknown contained barium, calcium, potassium, sodium, strontium, lithium, copper, or magnesium. Given a chart of the colors that each burn, lit the unknown on fire with a bunsen burner and compared the flame color with the colors in the chart. In order to identify the anion, we needed to perform four anion reactions: chloride, sulfate, nitrate, and carbonate. To identify…
