1. |
100cm3 volumetric flask is used in this experiment. Determine the amount of volume of hydrochloric acid of that need to used to produce a diluted hydrochloric acid of 0.2mol dm-3 by using the dilution equation.

2. |
10cm3 of 2mol dm-3HCl is transferred from the given solution into a 100cm3 volumetric flask by using pipette. |
3. |
Distilled water is added to the 100cm3 mark; the flask is then closed and inverted for few times until the solution is well mixed. A 0.2mol dm-3HCl solution is obtained. |
4. |
To prepare 100cm3 of 0.02mol dm-3HCl, step 2 and 3 are repeated using 10cm3 of 0.2mol dm-3HCl. |
5. |
To prepare 100cm3 of 0.002mol dm-3HCl, step 2 and 3 are repeated using 10cm3 of 0.02mol dm-3HCl. |
