The equivalence point for titration of 50 ml of 0.1 M formic acid, HCO2H (a weak acid) requires what volume of 0.2 M sodium hydroxide? less than 25 ml as formic acid is a weak acid. 100 ml. 25 ml. between 25 and 50 ml as formic acid is a weak acid. 50 ml.
a 100 ml solution of 0.250 M formic acid (HCOOH) was titrated to its equivalence point with 50 mL of sodium hydroxide. The complete molecular equation for the reaction is shown below HCOOH (aq) + NaOH (aq)---------> HCOONa (aq) +H20 (l) Ka of HCOOH= 1.7 x 10 ^-4 calculate the pH at the equivalence point
