Letting the subscript x stand for the unknown solution‚ x + s stand for the unknown plus standard‚ and Vt the total volume of solution‚ we can write Ax = ε bcxVx / Vt Ax + s = ε b(cxVx + csVs ) / Vt Dividing the first equation by the second and rearranging gives cx = Ax csVs 0.656 × 25.7 ×10.0 = = 21.1 ppm ( Ax + s − Ax )Vx (0.976 − 0.656) × 25.0 14-2.
