21 When determining titanium by the additive method, a sample of steel a was dissolved and the volume was brought to 50 ml. Then 20.0 ml aliquots of the solution were taken into two 50 ml volumetric flasks. A sample of titanium salt containing 0.0010 g of titanium was added to one of them. Hydrogen peroxide was added to both flasks and the volumes were adjusted to the mark. Calculate the percentage of titanium in steel if the following results were obtained during photometry of solutions:
a, g 0.6150
Dx 0.25
Dx st 0.45
