Concentration

The concentration of CDCL and CSER is obtained by solving equation (1) and (2) CX = A1 / ax1 ………………..... (1) CY = [A2 – (ax2 × CX)] / ay2…...(2) Where,  A1 and A2are absorbance of mixture at λ1 and λ2respectively.  ax1 and ax2 are absorptivities of DCL at λ1 and λ2, respectively,  ay1 and ay2 are absorptivities of SER at λ1 and λ2, respectively,  CXandCYare concentrations of DCL and SER, respectively. Concentration of DCL and SER in the powder mixture is found by using equation (3) and (4)…

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…

The goal of this lab was to find the molar sucrose concentration at equilibrium. Which is when the potato core and the sucrose solution reach equilibrium, so that no water is entering or leaving the cell. After collecting the data, the line of best fit never crossed the x-axis or showed where the molar sucrose concentration at equilibrium. I had to extrapolated the point at which it crossed the x-axis. This led to the data being unreliable because there is no physical evidence present that…

Figure 1 shows the relationship between concentration and absorbance known as the Beer-Lambert law or calibration curve. The data from the made solutions in table 2 was used to create the graph. The graph has a linear trend line that predicts where a point would fall on the graph. The equation of the trend line is equation 7: y=0.9508x-0.0055 with a R2 value of 0.99943. This equation was used to find the true concentration of the made solutions as well as the unknown solution. The R2 value…

absorbance behavior of triclosan in a solution. It acts as a viable way to measure the concentration of triclosan in a mixture. The data obtained using spectroscopy showed the soap sample contained 0.461% triclosan by mass. This coincides exactly with the information on the antibacterial concentration found on the bottle of soap. When using the spectroscopy method as a simple procedure for measuring the concentration of triclosan in a given mixture, outside data needs to be considered to…

The primary purpose of this experiment was to determine the concentration of solutions of copper (II) sulfate using visible spectrophotometry and Beer’s law. In this experiment, we used Beer’s law, which states that absorbance, i.e. the amount of light absorbed by a solution, is equal to the molar absorptivity of a compound, times the path length of the cuvette, times the concentration of the solution. First, we measured the absorbance of a cuvette filled with water, then calibrated the…

Daily Life in concentration camps was terrifying and draining emotionally and physically to the prisoners. The prisoners were always fearful of unnecessary beating and lashes from whips. The Nazi’s changed every person so that they could no longer feel or have emotions. The Nazi’s forced the prisoners to do unnecessary work in terrible conditions. Daily life in the Concentration Camps can be described as absolutely terrifying. The able-bodied prisoners worked in the slave labor complex. To…

the most known concentration camp case, Adolf Hitler hunting down Polish Jews to send them to internment(known as concentration camps). Prisoners in camps ended up living a painful life until death. The most well known method of death for prisoners in concentration camps was putting them to gas chambers. If you don’t know what are concentration camps, they’re camps that holds political prisoners, people that belonged to a specific race, religion, or ethnic group. The first concentration camp was…

different concentration camps and what effect did it have on the victims and the bystanders of the Holocaust? The significance of having three types of concentration camps was that Hitler, the SS and the Nazis were able to concentrate their sub-human victims. Having three types of concentration camps was an essential part of the Nazis ultimate goal of the Final Solution, as it dictated the fate of not only the victims but also the bystanders of the Holocaust. The three types of concentration…

It is expected that if the concentration of sucrose increases from 0.0 M, 0.2 M, 0.4 M, 0.6 M and 0.8 M (±0.01 g) in a 40 (±0.5) mL sucrose solution, then the average percent change in mass in Solanum tuberosum core will decrease. This is because if the Solanum tuberosum cores are placed in a hypotonic sucrose solution, which is described as having lower osmolarity, than the percent change in mass of the Solanum tuberosum core will increase due to the fact that water molecules will be moving…
