Colligative properties lab essay
The physical properties that the solution and solute do not share are known as colligative properties and they depend solely on the solute concentration some of these properties include vapor pressure lowering, boiling-point elevation, freezing point lowering, and osmotic pressure. Colligative properties- page 7 colligative property 2: boiling point elevation δt b = k b m molality which is the amount of solute added temperature constant which is the boiling point elevation constant for water increase because of solute for water, k b is 0512 o c/molal so. Colligative properties are properties of solutions that depend on the total number of solute particles in a solvent the number of solute particles effects both the freezing point depression and boiling point elevation of solutions. Colligative properties & osmotic pressure essay sample in this experiment, the objective was to observe the effects of some of the colligative properties of solutions the freezing points of distilled water and saltwater were measured, and found to both be about 0 °c.
Below is an essay on hands on lab colligative properties & osmotic pressure from anti essays, your source for research papers, essays, and term paper examples make two graphs of your data on one graph plot the data from the pure water. Colligative properties lab report sheet doc 10 pages cation analysis assignment indiana university, purdue university indianapolis experimental chemistry ii determination ka weak acid essay 2 pages crystalline structures essay indiana university, purdue university indianapolis. Since the colligative properties depend only on the amount of solute, not on its nature, the concentration of the 'stuff' in solution is actually twice that of the nominal concentration of the salt this must be accounted for in the case of electrolytes dissolving in water.
Colligative properties depend on the number of particles present, not on the type of particles or their mass osmotic pressure the osmotic pressure of a solution is the difference in pressure between the solution and the pure liquid solvent when the two are in equilibrium across a semi-permeable membrane, which allows the passage of solvent. Colligative properties depend upon: the type of solute particles the number of solute particles both the type and number of solute particles for a non-volatile solute, colligative properties are measured on: the solvent the solute both the solvent and solute the freezing point depression is defined as: t f - t f o.

Lab 9 colligative properties in this online lab activity you will use freezing point depression and boiling point elevation data to calculate the k f some colligative properties are vapor pressure lowering, boiling point elevation, freezing point depression and osmotic pressure. Colligative properties are properties resulting from the ratio of the number of solute particles to the number of solvent molecules in a solution they do not depend on the identity of the solute they can be applied to solutions.
Pre-lab questions 1 define the term colligative property, and list the four common colligative properties of solutions 2 (a) discuss the difference between an electrolyte electrolyte in terms of and a non-colligative properties, why is this difference relevant. We help our clients develop different kinds of academic writings including essays, research papers, dissertations, and term papers colligative properties order instructions answer the following pre-lab questions in your lab notebook prior to the start of lab. Chemistry experiment 3 colligative properties – freezing point depression objective to determine the molar mass of an ethyl alcohol solute by measuring the freezing point depression of a solution of this solute in a solvent as compared the freezing point of the pure solvent introduction colligative properties are a collective group of properties unique to solutions.

A lecture on colligative properties in an undergraduate curriculum boka w hadzija1 school of pharmacy, university of north carolina, chapel hill, nc 27599-7360 additional credit hour for the lab components of these courses although pharmacy as other health professions is colligative properties using many examples of how to calcu. Colligative comes from colligate –to tie together colligative properties have common origin colligative properties depend on amountof solute but do notdepend on its chemical identity. Colligative properties are all dependent upon the molality (m) of a solution molality is defined as moles of solute/kg of solvent the more, or less, of a solute that is present in ratio with the solvent will affect the calculations of the four colligative properties outlined above.
