Saturation

leaving the lungs of a healthy person at sea level pressure has an oxygen saturation level of 97 %. The saturation level will drop to 90% at approximately 10,000 feet. Folks in the medical industry consider an O2 saturation level below 93 % unhealthy. If an aircrew reacts slowly after an airplane depressurize at or above 25,000 feet, there’s a possibility that the crew would become unconscious. At that altitude the O2 saturation level is 55%. Prudent pilots that are aware of aeromedical factors, fly

Abstract In this experiment, the Ksp for calcium sulfate dihydrate, CaSO4·2H2O, by titrating 4 times a calcium sulfate dihydrate solution with diprotic EDTA, H2(EDTA)2-. For each trial we found the Ksp by means of molarities and activities. The results for the Ksp using only molarities was very different than the Ksp using activities. The average Ksp using molarity only was 2.26 x 10-4 and the average Ksp using activity turned out to be 2.31 x 10-5. The actual Ksp however, is 3.14 x 10-5. A percent

Saturation Assignment Questions Notes Describe the PLACE: Where are you? What do you see? What do you hear? What do you smell? At St. Mary's Square. A large statue of Dr. Sun Yat-Sen, the founder of the Chinese Republic. Also, a busy city. Lots of noise. Sounds of buses, people, and drum beats from a far. Looks like a lot of fish being cooked around. Describe the PEOPLE: Who is around you? What are they doing? What are their interactions? What is the mood of the people?

If a plant cell is surrounded by a solution with a high concentration of sucrose, then the cell will decrease in volume and mass. In this experiment, chunks of potato were placed inside 6 different solutions, each varying in concentration of sucrose. The potato chunk placed in water with 0 molars of sucrose added began with a volume of 2.025mm3, and increased to a volume of 2.268mm3 overnight. This was an increase in volume by 12%. This potato chunk began with a mass of 2.1 grams and increased to

The data collected from this experiment demonstrates that the potato undergoes a hypotonic change when exposed to water as well as a hypertonic change when saturated in a sucrose solution. Throughout the experiment, each piece of potato was introduced to a different concentration of a sucrose and water solution. The sucrose solution, due to its density, did not enter the potato cells while the water was easily diffused into the cells through pores in their membranes. Water undergoes osmosis in situations

The results of this experiment supported only part of my hypothesis. My hypothesis was that the potato in the 0m salt solution would create an isotonic reaction, the potato in the 0.2m salt solution would create a hypotonic reaction, and the potato in the 0.4m and 0.6m salt solutions would create hypertonic reactions. Although the results of the experiment say otherwise. In the 0m salt solution the potato gained mass. The initial mass of the potato piece was 4.79 grams and after it was placed in

The 0.0 M to 0.2 M sucrose solutions remained positive on the graph in figure one, while steadily approaching 0.00% mass difference. When the concentrations were 0.3 M to 0.5 M sucrose the percent mass difference became negative, decreasing continuously. As shown in Figure 1, the control 0.0 M sucrose solution yielded the highest percent mass difference (13.24%). From there, the percent difference in mass continually decreased in the treatment sucrose solutions; 0.1 M yielded a 4.76% difference,

Discussion When the degree of saturation Ω is equal to one, the system is at equilibrium. When Ω is greater than one, precipitation should occur because the solution is saturated in ions with respect to the solid mineral form. The data show that gypsum should have started precipitating between sample 1 and sample 2 collection time, because this is when the degree of saturation moves to beyond 1. The peak saturation for gypsum occurs between sample 3 and sample 4, and decreases afterwards. This decrease

solid dissolves. But only a certain amount of solid can be added to a volume of water before the solution becomes saturated and no more solid will dissolve. This saturation point can be affected by a number of variables including temperature. Task In pairs, conduct an experiment to determine the effect of temperature on the saturation point of ammonium chloride or potassium nitrate. A proposed method for conducting the experiment is outlined below. Prepare a practical report (1000-1500 words) that

Saturation vapor pressure is a unique function of temperature as given in Table 5.6. Each temperature in the table may be interpreted as a dew point temperature, because as the ground cools, dew will begin to form at the temperature corresponding to the vapor pressure.
