Extracellular Fluid Lab Report
Extracellular and Intracellular fluid
The first thing to be explained is intracellular fluid and extracellular fluid. Intracellular fluid is the liquid that is found inside cells. Extracellular fluid is found in things like plasma and this stands for all the body fluid outside of the cells. Intracellular fluid is separated by membranes and put into compartments.
Electrolytes
Electrolytes are found in the blood, urine and fluid inside cells in the body and in the space surrounding them. There are many different electrolytes in the body such as: sodium, magnesium, potassium and chloride. Electrolytes help the heart, nerves and muscles to work and function in the correct way. Electrolytes are electrically charged, this means they can send electrical impulses around the …show more content…
Petri dish- This is used to transfer the agar cubes as you should put the cubes in there as some of the chemicals can be dangerous
Safety goggles- These are essential to keep your eyes protected from harmful chemicals
White tile- To help to see the colour change
Stop clock- To time how long it takes for the cube to change colour.
Method
1-Stop the clock and quickly but carefully place one of the agar cubes into the specimen tube containing 3.7g/100cm3 of hydrochloric acid.
2-Close the tube securely with a bung and place the tube on its side in the petri dish to stop it rolling away. Place the dish on the white tile to help you see the colour change
3-Gather the results and record time taken for the block to completely change from pink to colourless.
4-Reapet steps A-C for each of the other acid concentrations
Results
The results that we produced from this experiment are shown below:
Time taken for complete colour change
Concentration of acid Time started First run (minutes) Time started Second run(minutes)
