Dilution Formula
M1V1=M2V2
Preparation of any Experiment
Clean all glassware used with soap and water, then rinse with distilled water
How much distilled water needed to prepare for 500mL volumetric flask?
3/4 of the entire 500ml volumetric flask or 375 ml
Where should the HCl concentration be transferred before collecting from pipet?
a Beaker
Where to transfer the HCl concentration inside the pipet?
To the volumetric flask
How many minutes do you need to stir the volumetric flask with solution in circular motion?
2 minutes
Why do we need to stir the volumetric flask with solution in circular motion?
To ensure that the solute and solvent has been incorporated properly
What do you do after making the solution?
Store it in a reagent bottle
After doing the experiment, what do you do with the glassware?
Clean with soap and water then rinse with distilled water
Why do we boil the water to 100 degree celsius and cool it down back to 40 degree celcius?
To ensure the gases are dissolved (oxygen and carbon dioxide), sterilizes water and makes the temperature stable throughout the experiment
Why do we need to rinse three times the beaker that was contaminated with NaOH?
To rinse the remaining NaOH present in the beaker
