1-Naphthaleneacetic acid

chemicals. I will explain how the class had gotten answer they did. And how they think it is right. The claim that will be explaining will be citric acid and baking soda. One of the first reasons that it is alike is when you turn the vial upside down it makes a does not stick to the sides of the vile. The same thing happens when you have citric acid and baking soda. When you shake the vial with the substance, it does not make a loud…

idea may be very simple, but requires great efforts because some developed countries have become so dependent on the combustion of hydrocarbons as an energy source. By limiting pollution such as sulfur oxides, nitrogen oxides, and carbon dioxide, acids would not be able to form within the atmosphere to create acidic solutions. The cut-off of air pollution would also solve other environmental problems. The solution seems to be to turn to renewable sources quickly to avoid further ocean…

It is well known that all organisms require at least some water to survive, even the most hardy creature on the planet earth, the tardigrade, Hypsibius dujardini, which can survive near complete dehydration, exposure to extreme radiation, vacuum, temperature and pressure, must be rejuvenated with water if it is to resume life after near complete desiccation (Gabriel, et al. 2007). H. dujardini, famous for surviving some of the harshest conditions of any organism we know of, is a perfect example…

either acid or base. Note: This activity may take more than one lessons. On the first lesson, students group, discuss and prepare their experiment. On the second lesson, students will have opportunities to carry out the investigation, then record, process, and evaluate their data. Preparing materials In the original experiment, hydrochloric acid and sodium hydroxide solutions have been used as acidic and basic solution, respectively. However, year 9 students might know that hydrochloric acid…

Determining the Chemical Formula of Hydrated Copper (Ⅱ) Sulfate Using the Empirical Formula Introduction In this experiment, the molecular formula of hydrated Copper (Ⅱ) Sulfate will be determined. In order to determine the molecular formula, the empirical formula is needed which is the ratio of moles of one substance to another. In this experiment, it is the ratio of Copper (Ⅱ) Sulfate to water. CuSO₄・XH₂O The empirical formula can be determined if the moles of the compared substances…

ACID-BASE PROPERTIES OF SODIUM CHLORIDE, SODIUM FORMATE AND AMMONIUM CHLORIDE INTRODUCTION The objective of this experiment is to examine the definitive characteristics of acids and bases by investigating the characteristics of strong versus weak acids; more specifically, why these differences are important in the process of titrations. In this experiment, there are two titrations performed and measured the pH of one salt solution. This experiment includes a strong acid and strong base…

containing 01Kg of dried fruit. Further The dried samples obtained were ground to a fine powder and stored at 5°C in air-tight containers prior to further analysis. Sample Preparation: Grounded samples of 10 g were extracted using 70% of ethanol (100 mL 1:10 w/v)) twice at room temperature for 24h and 6 h respectively. The mixture obtained were subsequently filtered with Whatman No. 5 filter paper. Filtrate obtained…

ANALYTICAL METHODS Determination of λ max Gemifloxacin mesylate λ max is determined by preparing one standard concentration of 10μg/ml and scanning should be done. Preparation of 0.1N HCL 8 ml of hydrochloric acid is taken in 1000ml volumetric flask and dissolved with distilled water and then make up to 1000ml with distilled water. Standard graph of Gemifloxacin mesylate: The λmax of Gemifloxacin mesylate in 0.1N HCL was scanned in UV-Visible Spectrophotometer and found to have maximum…

Tenofovir. l) pKa value: 3.75 m) Trade Name: Viread 2.2.5 Drug profile of Efavirenz: Efavirenz is an antiretroviral drug and it belongs to the class of Non-nucleoside reverse transcriptase inhibitor (NNRTI). It is used for the treatment of HIV type 1. Efavirenz was approved by the Food Drug and Administration on 21 September 1998. Efavirenz inhibits the activity of reverse transcriptase enzyme, which copies HIV…

A important tests were performed on the product to pressure the results: melting point value, percent yield, IR, and TLC. The experimental melting point value was found to be a range of 165-167 ºC being a little lower than the literature value for camphor, the intended product, was 175 ºC. The sharp range was resulted in a slightly pure product. The percent yield was lower than expected which can be the reason most of the product was lost during the extraction and almost completely sublimated…
