WebOct 9, 2024 · The finished reaction is: 2 KCl (aq) + Pb (NO 3) 2 (aq) → 2 KNO 3 (aq) + PbCl 2 (s) The solubility rules are a useful guideline to predict whether a compound will dissolve or form a precipitate. There are many other factors that can affect solubility, but these rules are a good first step to determine the outcome of aqueous solution reactions. WebJul 29, 2024 · We opted to run the calibration in 0.1 mol L −1 KNO 3 with the gain computed from a DPP also in 0.1 mol L −1 KNO 3. The procedure AGNES-SCP_1P.nox was applied (see Section F.2 in the Supplementary Materials). The retrieved value of η Q was 4.12 × 10 −5 C mol −1 L (see Excel file 220240_G_Cal_2_Zn.xls in Supplementary Materials).
