Potassium manganate

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 the least distance diffused. As expected, a negative correlation between the size of a molecule and the rate at which it diffuses exists. This explains why large, complex molecules need a carrier or channel protein to enter the cell. These molecules are…

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…

Magnesium is one of the most important minerals for human health and is required throughout the body; but by far the largest quantities are found in the bones and muscles. Almost all the body's enzymes are dependent to some degree on adequate supplies of magnesium, and these enzymes are essential for several hundred vital metabolic reactions; amongst the most important being the production of energy within cells through the metabolism of dietary proteins, carbohydrates and fats. Magnesium is…

After the experiment was conducted and the data was analyzed the cation in the solution was proven to affect the color of the flame. The cation in each of the solutions are calcium, copper, lithium, and potassium. The two salt solutions that have calcium as its cation are Calcium Chloride and Calcium Nitrate. When you compare those two solutions you can see that both of their flames turned orange. The two salt solutions with chloride as their anion were Calcium Chloride and Lithium Chloride.…

of nausea and acutely vomiting because of the pains in his stomach and throat. He was immediately rushed to the ED. His symptoms are diaphoresis, motor dysfunction, parethesias, nausea, ascending paralysis, cyanosis, and hypoventilation. He was prescribed with atropine due to the bradycardia. As he was assumed to be poisonous with tetrodotoxin which is a neurotoxin, intravenous hydration, gastric lavage and activated charcoal was conducted next. Background The extracellular fluid and…
