The following data was collected for the titration of 0.2M KOH with an unknown molarity of HCI. Calculate the volume used in each titration in the table below: Burette Readings Initial volume (cm³) Final volume (cm³) Volume used (cm³) (Titre) 1 0.00 25.25 2 25.25 49.00 3 49.00 74.00 4 74.00 97.85 Using the titration results in the table above, calculate the average volume of KOH used to neutralise the HCI. Using the result above, calculate the unknown molarity of the acid, HCI. Assume that a fixed volume of 25cm³ of HCl is used for each titration. Complete the table below by performing the appropriate calculations: Solution 0.1M Sodium hydroxide 0.1M Boric acid Vinegar Mineral water 0.1M Hydrochloric acid PH 12.26 5.02 3.43 6.67 1.28 [H*] (moldm³) POH Value [OH-] (moldm³) Give the following volumes with the appropriate units: (i) 20 21 22 23 24 25 (ii) 28 The following data was collected for the titration of 0.2M KOH with an unknown molarity of HCI.
