Question

A solution of HClO4 was standardized by dissolving 0.4008 g of primary-standard-grade HgO in a solution of KBr: HgO(s) + 4Br- + H2O → HgBr4 2- + 2OH- The liberated OH- consumed 43.75 mL of the acid. Calculate the molar concentration of the HClO4.

Step 1

- The atomic mass of Hg (mercury) is approximately 200.59 g/mol. - The atomic mass of O (oxygen) is approximately 16.00 g/mol. So, the molar mass of HgO is: \[ \text{Molar mass of HgO} = 200.59 \, \text{g/mol} + 16.00 \, \text{g/mol} = 216.59 \, \text{g/mol} \] Show more…
