Potassium

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…

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,…

At every barbeque, picnic, outing, or family get together, hot dogs are consumed. Millions of people adore hot dogs, and just cannot get enough of them. Millions are bought and devoured by the human race. They can be grilled or boiled, and then you can put ketchup, mustard, onions, and other delicious condiments on top. Most people are too busy adoring the food to ask, what is really in a hot dog? The first ingredient is mechanically separated meat. It is light pink and looks like strawberry…

Name: Ben Tanke, Brooke Binkley, and Hailey Fenn Block: 3rd Title: Gunpowder QPOEE Question: Which amount of Sulfur(.25 grams, .5 grams, .75 grams, and 1 gram) creates the closest reaction with fire as the store bought gunpowder in terms of size of flame and the time duration of the flame? Knowledge Probe: The equation for the reaction of our gunpowder is 10Na NO3 + 8C + 3S → 2 Na2 CO3 + 3Na2SO4 + 6CO2 + 5N2. This shows that Sodium Nitrate is reacting with…

Bam! Bam! Bam! goes the gun of a soldier. Have you ever wondered where gunpowder came from? Gunpowder, as well as silk and paper, are just some of many objects traded along the Silk Road that have an impact on our lives today. To begin with the silk road was a trading system and gunpowder was one of the objects exchange on the silk road.Gunpowder is made out of charcoal but it is also known as black powder. Gunpowder is a explosive chemicals which means it is very dangerous. Back to what I was…

The Thermodynamics of Potassium Nitrate Dissolving in Water Introduction: This experiment focuses on thermodynamics or the study of heat and molecular randomness. It helps illustrate how and why potassium nitrate (KNO3) dissolves in water. When it dissolves, it dissociates into potassium (K+) and nitrate (NO3-) ions. These ions can also recombine into solid potassium nitrate. This reaction can reach a state where concentrations of ions remain constant or Ksp; which stands for the equilibrium…

(200 mL), and 37% HCl solution (20 mL) to form 1.0 L solution. Both the stock solutions were sonicated to form clear solution. Cu2+ stock solution was prepared by adding water to a mixture of CuSO4·5H2O (5.0 g, 20 mmol), distilled water (700 mL), potassium sodium tartrate tetrahydrate (25 g, 89 mmol), and NaOH (7.0 g, 0.18 mol) to form 1.0 L…

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…

charge across the cell membrane is measured in (mV). The resting membrane potential is the difference between the charges inside and outside the sarcolemma. The intracellular concentration consists of sodium (Na+), potassium (K+), and Chlorine (Cl-). The concentration of potassium is high inside the cell and the concentration of sodium outside is high. The ion channels are watery pores in which ions can only cross through the neuron membrane (Pearson Cummings 2008). The ion channel is the…

Bury the fruit waste directly into the soil at the base of the plants. Lemon and orange rinds are high in potassium, and the potassium they contain is easily transferred over. Fruit and vegetables that are also high in potassium work too. ~ Phosphorus (P) - Low ~ 1. Why is phosphorus important in soil? What does phosphorus do for the soil? ~Phosphorus is essential in plants. Phosphorus is a component of DNA, RNA,…
