Question

20. You're becoming quite skilled at acid-base titrations. In another titration, you titrate 10.00 mL of 0.300 M KOH with 0.150 M HBr. (12) c. Calculate the volume (in mL) of titrant necessary to reach the equivalence point. Use circles to draw a particulate representation of the solution in the beaker when 10.00 mL of titrant is added to the beaker. Use one circle to represent polyatomic ions and omit water for clarity. Include a key. (3) d. 10.00 mL titrant added Calculate the pOH of the solution when 8.00 mL of titrant has been added pOH--loglHO], where [HO] is the molar concentration of hydroxide ions. (5) e.

Answer 1

Molarity =number of moles/volume

Therefore, number of moles= Molarity ×volume

1 OH^- require 1 H⁺

so when we add H⁺ to OH^- it react with it and form H₂O
