Unit 2 PPA 1 Complexometric Determination of Nickel using EDTA Introduction: The Aim of the experiment is to determine the percentage of nickel salt using a complexometric technique. Ethylenediaminetetraacetic acid (EDTA) is a hexadentate ligand which forms stable complexes with most metal ions‚ thus is widely used to determine metals in complexometric titrations. EDTA can be represented as H4Y and in alkaline conditions‚ it exists as Y+ ions: The Y4- ions form 1:1 complexes with metal ions

Hofstede’s dimensions of national culture Hofstede distinguished five dimensions of national culture: Power Distance (PDI)‚ Individualism/Collectivism (IDV)‚ Masculinity/Femininity (MAS)‚ Uncertainty Avoidance (UAI)‚ and Long-Term versus Short-Term Orientation (LTO). For those readers who are unfamiliar with his dimensional model‚ a short description follows. The dimensions are measured on index scales from 0 to 100‚ although some countries may have scores above 100 on certain dimensions because

put in place by the Peruvian government an option? Real options represent the right but not the obligation to make investment decisions once uncertainties unfold. Real options include management flexibility which is the concept that management can change their decisions about a certain investment over time when a particular aspect of the investment uncertainty becomes known. In real options‚ an initial choice is followed by more choices as additional information becomes available. Real options give

According to Table 5‚ the uncertainty associated with the temperature of the enzymatic solution at 40°C and 50°C read the volume as 31.70 mL at 40°C with a final uncertainty of ±0.06 and at 50°C‚ 28.80 mL. There is a positive correlation between the temperature of the enzymatic solution and the increase in uncertainty associated with the average volume of Pink Lady’s red apple juice extract with the exception of the final value as 14.90 mL with a ±0.05 uncertainty‚ this is attributed to possibilities
