Dissolve 0.59 g of Ba(NO3)2 in 1 L of water. Adjust the castile soap solution so that 2.4 mL of it will give a permanent lather with 40 mL of solution (b). When adjusted, 2.4 mL of soap solution is equivalent to 220 parts per million of hardness (as CaCO3) for a 40 mL sample. See also Soap solution. Brucke’s reagent (protein precipitation). See Potassium iodide-mercuric iodide. Clarke’s soap solution (estimation of hardness in water).. * Literature Review Boutron — Boudet soap solution 1. Dissolve 200 g of Rochelle salt and 150 g of NaOH in sufficient water to make 1 L of solution. 2. Dissolve 40 g of CuSO4 in enough water to make 1 L of solution. 3. Dissolve 50 g of Fe2(SO4)3 and 200 g of H2SO4 (sp. gr. 1.84) in sufficient water to make 1 L of solution. 4. Dissolve 5 g of KMnO4 in sufficient water to make 1 L of solution. Hypotheses * Hypothesis 1. Dissolve 100 g of pure powdered castile soap in 1 L of 80% ethanol and allow to stand over night Subhypotheses 2. Prepare a solution of CaCl2 by dissolving 0.5 g of CaCO3 in HCl (sp. gr. 1.19), neutralize with NH4OH and make slightly alkaline to litmus, and dilute to 500 mL. One mL is equivalent to 1 mg of CaCO3. * Bibliography Dissolve 200 g of Rochelle salt and 150 g of NaOH in sufficient water to make 1 L of solution. 2.
