Potassium sodium tartrate

Preparing Dilutions of the Silver Nanoparticles 1. Gather all materials. 2. Put on a pair of disposable gloves. 3. Make a paper towel damp with some 70% isopropyl rubbing alcohol. Wipe down the work surface with the rubbing alcohol-dampened paper towel. 4. Using a permanent marker, label the five baby food jars #1 to #5. 5. Using the 25 milliliter (mL) graduated cylinder, measure and pour 22.5 mL of distilled water (from a new, unopened container) into each of jars #2, #3, #4, and #5. 6. Using…

are cold. Dr. Richard L. Mueller defines TRPM8 as "an ion channel, upon activation it allows the entry of Na+ (sodium) and Ca2+ (calcium) ions to the cell that leads to depolarization and the generations of an action potential." In other words the TRPM8 cells open for sodium and calcium. However, in an article by Matt Soniak, he states that the TRPM8 ion cells don't only open to Na+ (sodium) and Ca2+ (calcium), but certain natural chemicals can activate TRPM8 on their own such as menthol that…

Purpose Ibuprofen is one of the most common over-the-counter medications. It reduces pain and inflammation by limiting certain hormones. The drug is taken orally, usually in the form of a pill, and is absorbed into the bloodstream once it dissolves. Both human saliva and human stomach acid aid in dissolving the pill. Human saliva has a pH of about 6, and stomach acid has a pH of approximately 2. The purpose of this investigation is to discover whether the pH of a solution will affect the time…

measure software. 5.2 Interaction study by FT-IR The infrared (IR) spectra of ARP, plain ME and optimized AME were taken using an IR spectrophotometer (Shimadzu FTIR- 8400 spectrophotometer). The plain ME, AME were spread as a thin layer onto a potassium bromide cell and then scanned between 4000cm-1 to 400cm-1 range. The resulting IR spectra of ARP and plain ME were then compared with AME to detect any possible interaction between the drug and different components used. 5.3 pH measurement…

In the present studies, we have made an attempt to investigate the catalytic activity of as synthesized AuNPs for a model reaction of reduction of 4-NP to 4-AP in the presence of sodium borohydride. The reaction was analyzed by measuring the absorbance of the reaction mixture in the wavelength range of 200-700 nm for fixed time intervals (Fig.8a-b). Initially, the absorption spectra of 4-NP (0.05 mM) showed the absorption peak at…

Synthesis of ZnO Nanostructures ZnO nanoparticles were prepared by using the following reagents : Starch solution Zinc nitrate hexahydrate {Zn〖(NO_3)〗_2 .6 H_2 O} Sodium hydroxide { NaOH) Freshly prepared ammonia solution. In order to prepare 0.01M of ZnO nanoparticles, the following steps were followed: The 0.01 M of Sodium hydroxide { NaOH} solutions in starch was prepared by adding 0.04 gm of NaOH powder dissolved in 100 ml of 3% starch solution. The solutions were stirred for 1…

experiment, a titration was carried out using a standard solution of hydrochloric acid to establish the molarity of a solution of sodium hydroxide. The concentration of acid in the gastric juice sample was determined using that solution of sodium hydroxide. The pH of gastric juice was then calculated and compared with the value determined by…

Pectin yield was determined as weight of dry pectin against the weight of initial residues multiplied by 100%. Y=100(P/Bi) Where Y is the extracted pectin yield (%), P is the amount of extracted pectin in grams and Bi is the initial amount of sweet potato residues used to extract pectin. Equivalent weight and Degree of methoxylation The equivalent weight was determined according to the method by Barretina et al., (Barretina et al. 2012). 0.25g pectin was wetted with 5ml ethanol and topped…
