  • Sucrose Diffusion Lab Report

    Analyzing Various Permeable Bags Placed in Different Concentrations of Water and Sucrose Introduction Osmosis is defined as the movement of water from a region of water that has a higher potential to a region of water that has a lower potential through semipermeable membranes. There are three types of solutions, hypertonic, hypotonic, and isotonic. Hypertonic solutions have a higher concentration of solute while hypotonic solutions have a lower concentration of solute. Isotonic solutions have an equal concentration of solute. There is no net movement going in or going out of the isotonic solution or solute. The purpose of this experiment is demonstrate osmosis by weighing the dialysis bag to indicate whether or not the bag is hypotonic, hypertonic or isotonic in the different concentrations of water and sucrose. By carrying out this experiment we will be able to better understand how the process of diffusion and osmosis works. My hypothesis is that diffusion will continue to occur throughout these various mixture of concentrations in the dialysis bags until equilibrium is reached. Once equilibrium is reached there should not be any net movement. Therefore, I predict that the bag with the higher concentration of sucrose will turn out to be hypertonic and while the lower levels of dialysis bags with sucrose will…

  • Adh Secretion Lab Report

    Discussion The results of this experiment for the hypotonic treatment group did support the tested hypothesis that urine production rate should increase, while salt concentration and specific gravity of urine should decrease for this group. For the isotonic treatment group, the tested hypothesis was supported in that the specific gravity and salt concentration went up slightly, but was not supported in that the the urine production rate did not greatly increase over time. The findings for the…

  • Potato Lab Report

    Abstract This lab was conducted in order to determine the molarity of sucrose concentration where the mass of 2cm^3 of Classic Russet potato segments and pear segments does not change, representing an isotonic concentration. By calculating the change of mass of the potato segment and pear segments prior to being placed in the sucrose solution against the mass after being in the sucrose solution for 45 minutes. Our goal was to determine what type of osmotic concentration was created as compared…

  • Chicken Egg Osmosis Lab Report

    the ability to easily identify which solutions were hypotonic, hypertonic and isotonic. Eggs that increased in size are said to be hypotonic because the solution has a lower solute concentration than the egg itself, the liquid then moves into the egg causing it to swell and burst. We can observe this when we look at the 0% sucrose solution; the weight of the egg increased 9.19 g throughout the 75 minutes. The solution from the mason jar entered the egg increasing its weight and creating a…

  • Creatinine Clearance Experiment

    This lab included various experiments that demonstrated how renal system responses and reacts when subjects consuming different types of fluids. Respective fluid volumes are based on each subject’s body mass. Based on each subject’s body mass, after converted from pounds to kilograms, every subjects has different volume and fluids for ingestion. For the control subject, she ingested no fluid throughout entire lab which represented the conditions of normal fluid. For the hypotonic subjects, she…

  • Fluid Balance In Nursing

    be the cause of the symptoms or be a result from a disease process or treatment; intravenous fluid administration is one commonly used method for treating these electrolyte and fluid imbalances. Hypertonic fluids have a higher osmolality than body fluids; examples of hypertonic fluids include D5/0.9% saline, 3% saline, D5/0.45% saline, and D5/Lactated Ringers (Trakalo, 2015). The difference in pressure gradients pulls fluid out of the intracellular space to create more volume within the…

  • Observing Osmosis

    becomes hypertonic, hypotonic, and isotonic. My hypothesis was that bag A would shrink because the water would leave the bag to go to the higher concentration. Bag B would stay the same because it would be isotonic. Bag C and D would swell because water would rush into the cell where…

  • Progressive Resistance Training Report

    throughout time. (Waller, 2010) Three type of progressive resistance exercises are commonly used, isotonic, Isometric, and Isokinetic. Isotonic exercise stimulates movement of a part of the body through a full range of motion (caused by the shortening and lengthening of muscles) via variable resistance from equipment. The resultant movement is not at a constant speed, but instead at a variable or changing speed. More simply put, isotonic exercises entail the conditioning of a group of muscles…

  • Water And Osmosis Experiment

    only being used once, and one cup filled with the only 100ml of Karo syrup. Using the materials above we measured the 7 model cells (or dialysis tubing filled with water) on the scale, writing down the mass of each. We then put the model cells inside the solutions and leaving them overnight. After returning to the lab station to finish the experiment, we took the cells out of the solutions, dried the tubing off with a paper towel and weighed the mass of the model cells on the scale. We used a…

  • Osmosis Egg Lab Report

    Fausto B. Mariano L. Daniel E. Diego R. Ms. Gudiño Science 3B 27/OCT/15 Lab Report Osmosis -Research Question: How will uncovering the egg shell by exposing the egg to vinegar will make it possible to understand the osmosis process in action? -Background information Diffusion: It's the net movement of molecules down a concentration gradient. This process allows small molecules like water and carbon dioxide to cross the Plasma Membrane. (Movement of dense areas to less dense areas.)…
