After this, 5 mL samples of the saturated solution were taken by pipette, diluted to 25 mL with water and titrated against 0.1 N sodium hydroxide solutions by using phenolphthalein indicator.", "reference": {"citation": "Timmermans, J.; Physico-Chemical Constants of Pure Organic Compounds (Elsevier, New York, 1950).", "pubtype": "book"}, "dataset": [{"series": 1, "title": "Solubility of heptanedioic acid (2) in acetonitrile (1)", "points": [{"pntnum": 1, "conditions": [{"property": "Ambient temperature", "number": "0e+00", "significand": "0.0", "exponent": "0", "sigfigs": "0", "unit": "&deg;C"}, {"property": "Ambient temperature", "number": "2.732e+02", "significand": "2.732", "exponent": "2", "sigfigs": "4", "unit": "K"}], "data": [{"property": "Amount Concentration (1)", "number": "1.5e-02", "significand": "1.5", "exponent": "-2", "sigfigs": "2", "unit": "mol/L"}], "supplemental": [{"property": "Percent mass fraction (2)", "number": "3.0e-01", "significand": "3.0", "exponent": "-1", "sigfigs": "2", "unit": "1"}, {"property": "Mole fraction - Liquid (2)", "number": "8e-04", "significand": "8", "exponent": "-4", "sigfigs": "1", "unit": "1"}]}, {"pntnum": 2, "conditions": [{"property": "Ambient temperature", "number": "1.50e+01", "significand": "1.50", "exponent": "1", "sigfigs": "3", "unit": "&deg;C"}, {"property": "Ambient temperature", "number": "2.882e+02", "significand": "2.882", "exponent": "2", "sigfigs": "4", "unit": "K"}], "data": [{"property": "Amount Concentration (1)", "number": "3.2e-02", "significand": "3.2", "exponent": "-2", "sigfigs": "2", "unit": "mol/L"}], "supplemental": [{"property": "Percent mass fraction (2)", "number": "6.5e-01", "significand": "6.5", "exponent": "-1", "sigfigs": "2", "unit": "1"}, {"property": "Mole fraction - Liquid (2)", "number": "1.7e-03", "significand": "1.7", "exponent": "-3", "sigfigs": "2", "unit": "1"}]}, {"pntnum": 3, "conditions": [{"property": "Ambient temperature", "number": "2.50e+01", "significand": "2.50", "exponent": "1", "sigfigs": "3", "unit": "&deg;C"}, {"property": "Ambient temperature", "number": "2.982e+02", "significand": "2.982", "exponent": "2", "sigfigs": "4", "unit": "K"}], "data": [{"property": "Amount Concentration (1)", "number": "5.5e-02", "significand": "5.5", "exponent": "-2", "sigfigs": "2", "unit": "mol/L"}], "supplemental": [{"property": "Percent mass fraction (2)", "number": "1.1e+00", "significand": "1.1", "exponent": "0", "sigfigs": "2", "unit": "1"}, {"property": "Mole fraction - Liquid (2)", "number": "2.8e-03", "significand": "2.8", "exponent": "-3", "sigfigs": "2", "unit": "1"}]}, {"pntnum": 4, "conditions": [{"property": "Ambient temperature", "number": "3.50e+01", "significand": "3.50", "exponent": "1", "sigfigs": "3", "unit": "&deg;C"}, {"property": "Ambient temperature", "number": "3.082e+02", "significand": "3.082", "exponent": "2", "sigfigs": "4", "unit": "K"}], "data": [{"property": "Amount Concentration (1)", "number": "1.2e-01", "significand": "1.2", "exponent": "-1", "sigfigs": "2", "unit": "mol/L"}], "supplemental": [{"property": "Percent mass fraction (2)", "number": "2.4e+00", "significand": "2.4", "exponent": "0", "sigfigs": "2", "unit": "1"}, {"property": "Mole fraction - Liquid (2)", "number": "6.3e-03", "significand": "6.3", "exponent": "-3", "sigfigs": "2", "unit": "1"}]}]}]}}
