A lab experiment for osmosis with potatoes involves putting half a potato in plain water and the other half in salt water and observing the difference in appearance. Osmosis is defined as the manner in which molecules pass through a membrane into a more concentrated solution.Know More
Only a few supplies are required for this experiment. Gather a large potato, knife, two plastic plates, salt and water.
The potato that was in plain water will not look much different than before, except it may be a bit more rigid. That is because the plain water moved into the potato's cells. The potato in the salt water will be slightly discolored, soft and flexible. This is because the contents of the potato's cells moved out of the potato and into the salt water by osmosis.Learn more about Chem Lab
A physics lab report is typically divided into five sections consisting of the abstract, the introduction or statement of purpose for the lab experiment, a description of the experiment's procedure, the actual results including data collected and the conclusions drawn from the experiment. These are fundamentally the same sections that appear in most scientific papers but shortened somewhat for student lab reports.Full Answer >
Some possible sources of errors in the lab includes instrumental or observational errors. Environmental errors can also occur inside the lab.Full Answer >
A Bunsen burner is a type of device used for heating in a laboratory setting. This apparatus works by adjusting the size of the flame by mixing gas and air in the appropriate amounts.Full Answer >
Errors in the chemistry lab can arise from human error, equipment limitations and observation errors. Some other sources of errors include measurement values that are not well defined and inconsistent experiment techniques.Full Answer >
