Potassium sodium tartrate

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…

properties of Sodium Chloride, being that it is not Hygroscopic, Efflorescent or Deliquescent. Thus, based on this experiment solely, it is not ensured that the salt is Sodium Chloride as 3 other salts share this…

Sodium polyacrylate is a polymer with a unique structure, that chemists are leveraging in a variety of lucrative industrial applications. Sodium polyacrylate possesses a unique chemical property: the ability to absorb incredible amounts of water. It can absorb 300 to 800 times its weight in water (Superabsorbent Polymers). Industrial chemists have taken advantage of the polymer’s special function, and have incorporated it into dozens of different products. In fact, the industry behind…

Since suitable crystals for X-ray single crystal analysis was not obtained, to have reliable structural information, HR-TEM analysis of the product was carried out. The average size of the assembly calculated from HR-TEM measurement is found to be 2.8 nm which is in good agreement with the size of the previously reported Pd6L8 assembly where L is the non N-methylated (2.5nm, Fig. 2).9 As first step, to explore the catalytic activity of 1 in copper and phosphine free Sonogashira coupling reaction…

Research Question: How do different concentrations of nitric acid (measured in molars) with copper powder (grams) affect the rate of reaction (measured in seconds) measured using a stopwatch? Hypothesis: The copper powder placed in the most concentrated amount of nitric acid, measured in molar, will take the least amount of time, measured in seconds, to react compared to the amounts of copper powder in other less concentrated amounts of nitric acid. This is as if the concentration of nitric acid…

In conclusion, we reported the synthesis of fused and isolated triazoles based on thieno[2,3-d]pyrimidines. The synthesized 1,2,4-triazolo compounds were screened for their anticancer activity at a concentration of 10 μΜ against a panel of 60 cell lines derived from nine different types of cancers, and also screened for their PDE 5 inhibitory activity. The possibility of combining 1,2,4-triazolo moiety to thieno[2,3-d]pyrimidines should open new opportunities for the rational design of…

Introduction: In this lab, seven test tubes containing solutions in equilibrium had different stresses added to them to examine the balance in each example. The purpose of the experiment was to indentify the details of shifting in equilibrium reactions and determine how the adding of a stress can affect a reaction. A chemical reaction that is in equilibrium is reversible, where a reactants can create products and products can go back to products. Equilibrium is reached when the rate of a…

Endothermic or Exothermic? The energy changes lab was an interesting lab in which the class compared two chemical reactions, the solute baking soda and the solvent vinegar, and the solvent baking soda solution with the solute of calcium chloride to see whether the changes were endothermic or exothermic reactions. I concluded that vinegar and baking soda was the endothermic reaction and baking soda solution and calcium chloride was the exothermic reaction. I knew this because in the vinegar and…

What I have found about this experiment is some really interesting ideas and other ways to the experiment. Some other people use Sodium or other words, for Sodium on the periodic table this chemical is called “Na” other people use that to make the Elephant Toothpaste. The call it Elephant Toothpaste because it’s supposed to look like toothpaste and since it's so big and it looks like toothpaste so the first thing people thought of was Elephant Toothpaste. Is that it was so deadly and that it…

Chlorine is a chemical added to swimming pools to keep the water free of bacteria and algae. Chlorine levels in swimming pools vary based on how much chlorine has already been used to remove bacteria and how much sunlight has broken down the chlorine molecules. This means that pool owners spend a lot of time testing and adjusting the levels of chlorine in their pools. To reduce the amount of time spent on pool maintenance, pool chemical manufacturer's created chlorine tablets. These tablets are…
