Approximately 40 mL of the ionized water was added to the 100 mL beaker‚ then in a 10-mL graduated cylinder‚ 5-mL of HCl was measured then added to the 100-mL beaker of water. The 100 mL beaker was then placed on the assembled ring stand. Approximately 40 mL of the 0.1M NaOH was added to the 250 mL beaker. The 40-mL of NaOH was then added to the buret which was then attached to the ring stand. The LabQuest and the Vernier pH sensor was then hooked up and turned on to measure and graph the pH of the

With my test result‚ it clearly shows that the concentration of sulfuric acid is 0.05 mol/dm3 using the concentration equation‚ c= n/v. 25 cm3 of the volume with sodium hydroxide is equal to 0.025 dm3 by dividing a thousand with cm 3 and multiply it with 0.1 mol/ dm3 which is the concentration of sodium hydroxide. With the ratio between sulfuric acid and sodium hydroxide is 1 to 2 so‚ 0.0025 should be divided by 2 and 0.00125 moles of sulfuric acid is come out. Finally‚ using c = m/v‚ 0.00125 mole/0
