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
