In Table 4 below, [Fe] after mixing is obtained by using M₁V₁-M₂V₂ This data is to be transferred to Table 5 below as the initial [Fe³"] (column 2). Similarly in Table 4 of Data sheet [SCN] after mixing obtained using M₁V₁-M₂V₂. This data is then to be transferred to Table 5 below as the initial [SCN] (column 3).
