Osmosis


Aim: to investigate the effect of solute assiduousness on the assess and direction of osmosis by comparing the mass (and therefore body of wet content) of a shell-less egg before and after immersion in solutes of different salt concentration.

Independent Variable: salt concentration of the solutions (0%, 1%, 5%, 10%).

Dependant Variable: ramble and direction of osmosis (measured by the eggs change in mass).

possible action: as the salt concentration of the solution increases the rate at which water diffuses into the egg by osmosis will also increase, causing in an increase in the eggs mass.

Thermometer
salinity (NaCl) solutions of 1%, 5% and 10% concentrations
Paper toweling
Distilled water
Plastic container

function
Materials
2 fresh hens eggs
2M Hydrochloric acid
Gloves
2 250ml beakers
sprightly roll
Electronic scales

Method
1.Tare a plastic container on the electronic scale.
2.Without touching it, gently unwrap one egg and press it by placing it in the plastic
container on the electronic scale. armorial bearing should be taken never to touch the egg with spare hands to minimise the risk of food intoxication from ingesting part of the egg.



Touching or breaking the eggs membrane would not only introduce a source of hallucination but would present a risk of food poisoning if part of the egg was ingested. Record the eggs clog in a table. Re-wrap the egg in glad wrap and take it out of the plastic container.
3.Repeat step 2 for the second egg.
4.Rinse two 250ml beakers with distilled water to remove whatever dust and possible chemical residues.
5.Half fill individually 250 ml beaker with distilled water.
6. concurrently place one egg in each beaker and start the stopwatch. Using a thermometer measure the water temperature in each beaker and record in a table.
7. afterward ten minutes measure and record the water temperature again. Simultaneously remove both eggs from the beakers and pat them dry with paper toweling. Weigh each egg and record its weight in...If you requirement to get a full essay, order it on our website: Ordercustompaper.com
