A buffer solution can maintains a narrow range of pH even when strong acid are added. In our experiment‚ we can see water is not a buffer‚ water can undergo very big changes when small amounts of strong acid or strong bases are added. When the strong acid‚ 100µl HCl was added into the dd water‚ the pH value changed from 7.38 to 5.83 which mean the dd water has turn into acid. The same phenomenon occurs while strong base‚ 100µl NaOH was added into the dd water. The pH value changed from 7.07 to 9

“An organization is a place with definite goals and objectives. It has several people working to achieve those goals. Some work at a smaller level‚ while some work at a higher level. However‚ everyone works for the development of the organization. Planning‚ organizing‚ managing‚ controlling and sustaining are the keys to organizational growth and development. At the departmental level‚ all these tasks are done by the supervisory level people and the junior management. But‚ who is the person taking

Irodov Problem 3.7 As shown in Figure 1‚ the charges are located in at the four corners of the square ABCD whose diagonal is of length 2l. Since the point Xis located at a height of x units from the plane of ABCD along its central axis‚ the distance of X from any of the corners A‚B‚C and D is . The electric field strengths due to each of the four charges located at corners A‚B‚C and D are given by‚ The vertical components of EC and EB will cancel

Solutions for Homelessness This great nation of awesome power and abundant resources is losing the battle against homelessness. The casualties can be seen on the street corners of every city in American holding an "I will work for food" sign. Homeless shelters and rescue missions are at full capacity. There is no room at the inn for the nation’s indigent. Anyone who has studied this issue understands that homelessness is a complex problem. Communities continue to struggle with this socio-economic

Electrolytic Solutions Solutions are sometimes grouped according to their ability to conduct electricity. Substances whose solutions conduct electricity are called electrolytes and those that do not conduct electricity are called nonelectrolytes. Also electrolytes can be strong or weak. Under strong electrolytes we have NaCl and CaCl2 which are ionic compounds‚ HCI‚ HNO3‚ HBr and H2SO4 are under acids and NaOH‚ KOH‚ and LiOH are under bases. Weak electrolytes are ionic compounds and slightly

Kristin’s Cookie Company Solution This is what the process looks like. [pic] 1. The capacity of the system is based on the output of the bottleneck. The bottleneck is the oven‚ which can process 60min/10min = 6 dozen orders per hour. This assumes one-dozen order sizes. 2. The throughput time is the sum of the processing times for each of the steps. This equals 8+10+5+2+1=26 minutes. 3. In a four-hour shift you can produce the hourly capacity for each hour. This

non-agri products than agri products. However an increased focus on non-agri products may lead to a loss of core customer focus and trust. Further‚ it is seen that ‘spoke’ stores tend to break even in 2 years while ‘hub’ stores take 3 years. In addition to increasing sales‚ variable and fixed costs must be controlled. Increased competition must be tackled. Solutions must be found to hasten operational breakeven without losing customer focus. Options: Modify the hub/spoke model. Add more spokes so
