between concentration of hydrochloric acid (HCl) and the rate of diffusion?” My hypothesis for this research question is that change in rate of diffusion will be observed when the agar blocks are placed in solutions of different concentrations of HCl. As the concentration of HCl increases‚ the rate of diffusion will also increase due to the steeper concentration gradient created. To investigate the change in rate of diffusion when different concentrations of HCl are used‚ I used agar blocks that are stained

Experiment 11.1 Conversion of t-Amyl Alcohol to t-Amyl Chloride Using HCL October 27‚ 2011 Purpose: Alkyl halides can be prepared from alcohols by reacting them with a hydrogen halide‚ HX (X = Cl‚ Br‚ or I). The mechanisms of acid-catalyzed substitution of alcohols are termed SN1 and SN2. The “S” stands for substitution‚ the “N” stands for nucleophilic‚ and the “1” or “2” stand for unimolecular or bimolecular. Secondary alcohols react with hydrogen halides by both SN1 and SN2

The full strength 1M HCl acid had a pH level of 3.12 (Table 3.1). Sample A2 to A4 remained in the pH 3 level‚ while sample A5 and A6 had a pH range of 4 (Table 3.1). The pH level for 1M HCl dilutions slightly increased between each sample (Table 3.1). The diluted solutions of 1 M NaOH showed a few unexpected results. The original solution of 1 M NaOH was at a pH level of 11.50 (Table 3.1). However‚ the pH of sample B2 increased to 12.81 (Table 3.1). The remaining samples had a decreasing pH pattern

Determining the Ksp of Calcium Hydroxide by Titration of Saturated Ca(OH)2(aq) with HCl(aq) Abstract: Titration is a technique that has been used in this experiment to identify the Ksp value of calcium hydroxide in order to determine the extent to which the compound is soluble in water. A known volume of 50 mL of hydrochloric acid‚ a concentration of 0.05 M hydrochloric acid‚ a volume of 50 mL calcium hydroxide base‚ an unknown concentration

1. Gather all the equipments needed. 2. Measure 50ml of HCL in a 250 ml measuring cylinder and pour it into a flask‚ then measure 50ml of HCL again and pour it into the second flask. 3. Measure the 50ml of KOH in a measuring cylinder. Repeat it again in another measuring cylinder. 4. Attach both of the burette clamps to both of the burette stands and clamp the burette at a certain level so that it can fit a flask underneath. 5. Then‚ place a funnel on top of each burette. 6. Place a flask underneath

financial reporting standards around the world‚ with particular reference to investors and multinational firms. What are the disadvantages of moving toward a set of global standards and what barriers need to be overcome to achieve the goal of standardization? (ESSAY) As people need to speak the same language to understand each other while talking‚ participants on the global market also need to have similar accounting language in order to communicate in between. For that reason‚ it is not a surprise
