Respuesta :
The concentration of the 2.22 mL perchloric acid that was neutralized with barium hydroxide is 3.1 M.
What is neutralization?
The neutralization is given as the reaction of the acid and the base forming salt. The reaction of 1 mole of barium hydroxide requires 2 moles of perchloric acid to neutralize completely.
The volume of barium hydroxide given was 15.1 mL. The moles of barium hydroxide has been:
[tex]\rm 1000\;mL\; Ba(OH)_2 = 0.2288 \;mol Ba(OH)_2\\\\15.1\;mL\;Ba(OH)_2=0.0034\;mol[/tex]
The moles of perchloric neutralized by 0.0034 mol barium hydroxide will be:
[tex]\rm 1\;mol\;Ba(OH)_2=2\;mol\;HClO_4\\\\\rm 0.0034\;mol\;Ba(OH)_4=0.0069\;mol\;HClO_4[/tex]
The volume of perchloric has been 2.22 mL. The concentration of the acid is given as:
[tex]\rm Concentration=moles\;\times\dfrac{1000}{volume(mL)}\\\\Concentration=0.0069\;mol\;\times\dfrac{1000}{2.22}\\\\Concentration=3.1\;M[/tex]
The concentration of the perchloric acid aliquot is 3.1 M.
