Isotonic

Hypotonic and Isotonic. The Hypertonic solution has a higher concentration of NaCl. The Hypotonic solution has less concentration of NaCl. The Isotonic solution has about the same NaCl content and the blood cell. Based on the facts that water molecules are always moving from a high concentrated to low concentrated gradient, the water molecules will move out of the red blood cells when placed in hypertonic solution and will swell up when placed in the hypotonic solution. In the Isotonic solution, the

hypotonic which means that the solution has a lower concentration than the potato core and this would cause water to flow into the potato and make it larger and therefore increase its mass. The state the cell is in is called turgid. It could also be an isotonic solution. This is when the concentration (or molarity) of the cell is identical with the concentration of the solution. In this case the cell (or potato core) stays the same in size, which is called flaccid. No water moves either in or out of the

to the isotonic saline solution, blood concentration increased, therefore the protein concentration become greater in the solution. The greater concentration of protein in the solution the more light is scattered. The intensity of the scattered light increased, resulted in a lower voltage was detected by the LIM device. Thus resulted in a trend of decreasing voltage with an increasing blood concentration. Figure 1 indicates that the output of the LIM is linear. RBCs were added in an isotonic solution

for the topic of osmosis, the movement of water from high to low concentration. Five artificial cells were created, each being filled with different concentrated solutions of sucrose. These artificial cells were placed in hypertonic, hypotonic, or isotonic solutions for a period of 90 min. Over time, the rate of osmosis was measured by calculating the weight of each artificial cell on given intervals (every 10 minutes). The resulting weights were recorded and the data was graphed. We then could

In their case study, “Fatal hyponatremia in a young woman after ecstasy ingestion,” Kamyar Kalantar-Sadeh, Minhtri Nguyen, Roger Chang, and Ira Kurtz present a 20-year old female, Asian-American, college student who took multiple tablets of ecstasy and drank excessive amounts of water at a party. This student was found the next morning, unresponsive, foaming at the mouth, with rapid and shallow breathing, and a weak pulse. After being admitted into the emergency room, the patient was determined to

diffusion and osmosis to see the effects of either corn syrup or water on a shell-less raw egg over a three day period. While looking to see the effects of these liquids on the raw egg, one can also apply the properties of hypotonic, hypertonic, and isotonic solutions. Introduction Cells have an outer covering called the cell membrane. The membrane is selectively permeable meaning that it has tiny pores or holes that allow objects to move across it. The cell membrane controls what moves in and out of

Definitions and Preliminary Observations: Finding the Isotonic Point of Potato Cells In this lab we will be doing an experiment to find the isotonic point of potato cells by placing potato cores in solutes with varied and measured concentrations of urea. Other solutes will be tested by other groups following the same procedure. We will track the change in weight by removing the cores and weighing them at timed intervals. In order to understand how and why we will be following this protocol,

In order to understand how this could cause irritation, one must understand the basic mechanisms of isotonic and hypertonic solutions. Isotonic solutions match the osmolality of the blood, which is around 280mOsm/L – 310mOsm/L. This type of solution is used to enhance the fluid volume within the blood vessels. As for hypertonic solutions, they have a higher solute to solvent ratio, which means the solutions’ osmolality is higher than the normal serum levels and the pH is lower than the normal serum

Cell function changes depending on the types of fluid loss. There are three types of fluid loss: Isotonic fluid, hypotonic fluid, and hypertonic fluid. The isotonic fluid loss means that the water loss is in the same proportion to the electrolytes. Water and electrolytes are lost from extracellular compartment first. Then, they are moved out of the cells to replace the loss in extracellular fluid. Since there is no osmotic pressure change, there is no shrinkage or swelling of the cells, but only

cells had different isotonic points and, therefore, proved that the internal solute concentration of plants in a different environment are different. To elaborate further, the isotonic point is defined in this lab as having about 50% plasmolyzed and 50% unplasmolyzed cells in a specific species. In terms of salt concentration, a higher isotonic point indicates that the solute concentration inside the cell is higher than outside the cell. For example, plant cells with an isotonic point at 4% salt concentration
