Potassium sodium tartrate

surface, such as 1 part per million, are enough to catalyze Luminol’s chemi-luminescence (react and cause it to glow). However, Luminol sensitivity is not blood-specific, and the compound also reacts with other substances for example, saliva, rust, potassium, permanganate, animal proteins, vegetable enzymes, etc. Therefore, Luminol tests [aren’t] [decisive] for blood and cannot be admitted for evidence in court. (“Lerner & Lerner,…

3-(4-acetylphenyl)-6-bromo-2-(4-chlorophenyl)quinazolin-4(3H)-one (2) Compound 1 ( 0.01 mol) fused with p-aminoacetophenone ( 0.01 mol) at 160 oC in an oil bath for 2 h. Crystallized from ethanol to give redish brown crystals of 2, m.p. 210oC in 80% yield. Analysis for C22H14BrClN2O2, Calcd.: % C, 58.24; H, 3.11; N, 6.17, Found: % C, 58.31; H, 3.17; N, 6.20, IR spectrum (KBr, cm-1) showed characteristic absorption bands at 3380 (C-H aromatic), 1710 (C=O of acetyl), at 1690 (C=O of…

Creating food: Before making the food, make sure to wash your hands thoroughly. After washing your hands, make sure to wipe down your station before using it. There are alcohol spray bottles throughout the lab. Spray it in your area and use the paper towels to wipe it down. Obtain a clean polystyrene vial and fill one eighth of the tube with dry food. The fly food was purchased from the Carolina Biological Supply company. Add about 9 ml of water to the dry food and gently roll the vial five…

As it can be seen the concentration of the phenol compounds decreased as the hydrogen peroxide increases. The presence of the anions decreases the rates of the phenolic compounds, the sulfates influence in a smaller degree. For phenol and 2-nitrophenol the difference in slope or degradation rates for chloride and sulfate are 0.71 and 0.55, and only 0.16 for 2-chlorophenol. The presence of chloride inhibits in greater proportion the formation of hydroxyl radicals than the sulfate , this can be…

from words are essential skills in chemistry. Before we proceed with the lesson, let us remember that when we refer to single elements such as carbon, magnesium, we can easily refer to the periodic table and write down their symbols. Carbon is C, potassium is K and Magnesium is Mg in chemical reactions. There are, however, seven elements that exist as __‘’diatomic molecules’’__, which are molecules that are composed of two atoms of the same element. These are: hydrogen, nitrogen, oxygen,…

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 Carbon/Charcoal and Sulfur to form Nitrogen, Carbon Dioxide, Sodium Carbonate, and Sodium Sulfate. In gunpowder, the Sodium Nitrate is decomposed at a high temperature to produce oxygen for the gunpowder reaction. Since the Sodium Nitrate is able to…

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…

Fireworks have a few different parts such as Potassium Nitrate, Charcoal, and Sulfur and they use different chemical compounds to create three kinds of results: A tremendous "boom" A bright light Heat What is the recipe for black powder? Why do you think Potassium Nitrate, Charcoal, and Sulfur become explosive after they are ground together? Black Powder is a mixture of Potassium Nitrate, Charcoal and Sulfur. The Sulfur and Charcoal act as fuels, and the Potassium Nitrate is an oxidizer.…

In part one the Styrofoam cups and the substances that are in the cup which is distilled water and sodium hydroxide was the system while the stir rod and thermometer and the Vernier unit is the surroundings. In part two the Styrofoam calorimeter, HCl and NaOH are the system while the stir bar and the tool that is used to measure the temperature is the surroundings. In part 3 HCl, Styrofoam cup calorimeter and NaOH are the system while the temperature probe, stirring rod are the soundings 6.)…

Checking your car's battery is an extremely important part of car maintenance. If you keep your battery clean and running in tip top shape, it will last much longer. When checking your battery, you should look for problems like corrosion, dirt, cracks, and broken cables. It's important to be cautious when working on your car's battery. You should always make sure the engine is off and you are removing the battery and its cables correctly so that you don't cause harm to yourself or the battery.…
