How many resonance structures does HSO4- have? The way I've been doing it would make it 12 but that seems like it'd be too many.
determine the minimum concentration of the percipitation the cation from the solution of the left. 0.035 M BaNO3; Naf.
potassium hydrogen phthalate is a monoprotic acid. Dihydrogen phthalate(H2C8H4O4) is a diprotic acid. An analyte sample contains 0.127 M KHP and 0.0678 M H2C8H4O4. What volume of a 0.205 NaOH solution is required to neutralize 25.0mL of the analyt..
