Question
I need help! I'm confused with this problem and cannot evenstart. Here goes the problem: An environmental chemist analyzed the released wastematerial from an industrial process that was known to produce amixture of several compounds, including benzoic acid(HC7H5O2) a monoprotic acid. A0.3518-g sample of this waste material was shaken in water todissolve the benzoic acid. The resulting aqueous solution required10.59 mL of 0.1546 M NaOH for neutralization. a) Write a blanaced net ionic equation for this neutralizationreaction. Please include state symbols such as (s), (aq),etc. b) Calculate the percent by mass of benzoic acid in theoriginal sample. *My comment: If you don't have time to solve all this, can youplease teach me what's happening when I shake the benzoic acid inwater? What acqueous product do I get? Thank you! I need help! I'm confused with this problem and cannot evenstart.

The total ionic equation isHC6H5CO2(aq) + Na+ (aq) + OH¯(aq) ===> Na+(aq) + C6H5CO2¯(aq) + H2O (l) spectator ions: Na + HC6H5CO2(aq) + OH¯(aq) ===> C6H5CO2¯(aq) + H2O (l) when benzoic acid is dissolved in water its acqueous solutionis formed. HC6H5CO2(aq) + OH¯(aq) ===> C6H5CO2¯(aq) + H2O (l) when benzoic acid is dissolved in water its acqueous solutionis formed.
