Results and discussion 3.1 Ionic conductivity measurements The complex impedance plots for the polymer electrolytes with different amounts of TBAI /LiI is shown in Fig. 1. It can be displayed that the ionic conductivity increases with the increase in TBAI salt content and reaches the maximum value of 1.737×10-3 S cm-1 at 298 K for 60 % of TBAI content, beyond decreases on further addition of TBAI. At a low content of TBAI, the conductivity is low due to the small number of charge carriers in…

The concentrations of difference between the membrane phase and feed phase based on the mechanism of mass extraction. In the case of feed solution represented radioactive simulated waste solution and dissolved in 0.5M HNO3. In the feed phase decreasing with H+ concentration. pH values at 2.5 into 5.5 in the feed phase. Fig,s(5a-5c). Shown the effect of hydrogen ion concentration in the feed phase and studied of pH range 2.5-5.5 for 0.5M HNO3. Stripping solution of 0.05M of EDTA. Initial…

Describe the Properties of Biopol Biopol is a copolymer made of the monomers PHV and PHB. PHB alone, with its short methyl side chain, is brittle and has very high crystallinity, meaning it cracks easily. Due to its high crystallinity and overall unsuitable properties for industrial use, PHV has been added to created PHBV, or Biopol. Biopol is semicrystalline, meaning it can still crystallize as well as melting at a lower temperature than PHB, making it industrially suitable. Due to its long…

The value in setting goals is finding the courage and commitment to achieve them. I have dedicated countless hours to my challenging coursework in hopes of achieving my goal of earning a Bachelors in Chemical Engineering. Hundreds of other hours have been put into church and clubs that I hope I will continue to participate in. Especially, since those programs helped me grow as a person while helping others. I push myself to work to my best in hopes that; ultimately, I will find a satisfying and…

Aim: This is an investigation to establish the effect of different temperatures (from 0°C -100°C) on the production of oxygen gas in a potato catalase reaction, using hydrogen peroxide as a substrate. The oxygen gas produced will be measured using a gas pressure sensor. Introduction: Enzymes are proteins, known as biological catalysts that increase the rate of reaction in a biochemical reaction without being chemically altered. The human body consists of various different types of enzymes,…

The rate at which a reaction occurs, referred to as reaction rate, is a type of reaction property that directly measures the extent of a reaction. Changes in concentration affect reaction rates in chemical formulas, and if the reaction is not specifically known, the rate cannot be determined. The rates are given in negative or positive measurements depending on whether the concentration is a reactant or product. Knowing this, the first step in finding the reaction rate would be to determine the…

This lab is designed to find the mass of copper produced when excess aluminium is reacted with 2.00g of copper salt [Copper (II) chloride decahydrate]. This will be achieved by dissolving the given amount of copper salt in distilled water and then adding in the aluminium rod. The reaction will commence as copper will begin to form on the aluminium. Calculating the percent yield is commonly used in the atom economy of a chemical reaction, which is a measure of the initial substance which becomes…

1. Identify the key technical characteristics of the Daguerreotype and Calotype processes. Illustrate your answer with examples of images form each technology, and say how they reflect its characteristics. (25%) Before the invention of the wet collodion process, which produces an unlimited number of copies of finely detailed images on paper and to print, by Frederick Scott Archer in 1851, there were two photograph processes previously: the daguerreotype and the calotype. The…

The lab calculations resulted in an average of 21.7L/mol which was fairly close to the theoretical value, 22.4L/mol. In order to obtain that result through calculations, the water vapor pressure and the water height correction had to take place. After, the combined gas law had to be utilized and manipulated to find the volume and divide that volume by moles of magnesium. Being close to the theoretical value, 22.4L, it verifies that one mole of all gases occupy 22.4L in any container under…
