Pour 50 mL of 1 mol/L HCl into a 100 mL beaker. Label the beaker as " 1 mol Hcl"
Using the dropper, transfer 1 Ml of the 1 mol/L HCl into a 250 mL beaker and add 100 mL water. Stir. Label beaker as "0.01 conc. HCl"
Using a cleaned dropper, transfer 1 mL of the new solutions into a 250 mL beaker and add 100 mL of water. Stir. Label beaker as "0.0001 conc HCl"
Weigh out 2 g of NaOH, place in a 100 mL beaker and add 50 mL water. Stir until dissolved. Label beaker as "1 mol NaOH"
Repeat steps 2-3 with the NaOH solutin
Pur 10 mL of each of the prepared solutions into separate test tubes and label them with their corresponding solutions.
Pour 10 mL of the distilled water into another test tube.
Arrange the 7 test tubes in order from most acidic to neutral to most alkaline. Add 2-3 drops of one of the indicators and record the colours of the solutions.
Repeat steps 6-8 for each of the indicators
