Exactly 17.0 mL of a H2SO4 solution was required to neutralize 45.0 mL of 0.235 M NaOH. What was the concentration of the H2SO4 solution? Given: H2SO4 (aq) + 2NaOH (aq) → 2H2O (l) + Na2SO4 (aq)

#sf(0.31color(white)(x)"mol/l")#

Explanation:

#sf(H_2SO_4+2NaOHrarrNa_2SO_4+2H_(2)O)#

#sf(n_(NaOH)=cxxv=0.235xx45.0/1000=0.010575)#

#:.##sf(n_(H_2SO_4)=0.010575/2=0.0052875)#

#sf(c=n/v)#

#:.##sf([H_2SO_4]=0.0052875/(0.0170)=0.31color(white)(x)"mol/l")#
