1. A 25 cm3 of 2M/dm3 solution of Sodium ehtnadioate was placed in 500 cm3 volumetric flask. What will be the concentration of this solution? 2. Write an equation for the reaction of ehtandioate with HCl. 3. 25 cm3 of the ethandioate solution made in (1) was titrated with HCl. The average titre volume of HCl required to neutralise this solution was 23.5 cm3. Using the information given work out the concentration of HCl in mol/dm3. Give your answer to 3 decimal points.
