For the complexometric titration of Ca (II) ions in the shell of the egg sample weighing 59.427 g, necessary procedures were applied to the egg shells and 100 mL sample was prepared. 1 mL of the prepared sample was taken and diluted to 100 mL, the pH was adjusted, and two drops of EBT indicator were dropped on it. The solution prepared was titrated with 27.4mL of 0.0097 M EDTA solution. Calculate the amount of calcium in the sample in terms of% CaCO3. (Ca = 40 g / mol, CaCO3 = 100g / mol)
