77-09-8: Density: 1.385 g/cm 3: Solubility: Water: 0.1 g/100 mL Melting Point: 258-263 °C: Formula: C 20 H 14 O 4: Boiling Point: 557.8 °C at 760 mmHg Molecular Weight: 318.32 Flash Point: 206.5 °C Transport Information The boiling point of water is 100 degrees Celsius. Phenolphthalein: EINECS: 201-004-7 CAS No. They can, but only slightly. This boiling-point difference of 16.1 millikelvins between the Celsius scale's original definition and the previous one (based on absolute zero and the triple point) has little practical meaning in common daily applications because water's boiling point is very sensitive to variations in barometric pressure. The Celsius scale sets the freezing point and boiling point of water at 0°C and 100°C respectively. Boiling Point: 557.8±50.0 °C at 760 mmHg Vapour Pressure: 0.0±1.6 mmHg at 25°C Enthalpy of Vaporization: 87.1±3.0 kJ/mol Flash Point: 206.5±23.6 °C Index of Refraction: Phenolphthalein is a chemical compound with the formula C 20 H 14 O 4 and is often written as "HIn" or "phph" in shorthand notation.Phenolphthalein is often used as an indicator in acid–base titrations.For this application, it turns colorless in acidic solutions and pink in basic solutions. is liable to change without any intimation or notice. 77-09-8: einecs no. Color change: colorless to pink at ~pH 8.3. phenolphthalein: product identification. Ltd. makes every effort to ensure that the information Pepper has the least effect on the boiling point because it doesn’t really dissolve well in liquids. An estimated BCF of 14 was calculated for phenolphthalein (SRC), using a log Kow of 2.41 (1) and a regression-derived equation (2). Stiffness is … It belongs to the class of dyes known as phthalein dyes. Celsius scaled his measurements as 0 for boiling point and 100 for freezing point but the order was later reversed. or. Example. Find chemicals information Phenolphthalein at guidechem, professional and easy to use. Guidechem provides Phenolphthalein chemical database query, including CAS registy number 77-09-8, Phenolphthalein MSDS (Material Safety Data Sheet), nature, English name, manufacturer, function/use, molecular weight, density, boiling point, melting point, structural formula, etc. Click to see full answer. Very sensitive to CO 2; and, in estimating carbonates, the liquid must be boiled.Borax can be titrated with phenolphthalein as an… View information & documentation regarding Phenolphthalein, including CAS, MSDS & more. You might have been told that water boils at 100 degrees Celsius (212 Fahrenheit) but the boiling point of water actually depends on the oxygen content and atmospheric pressure. Celsius, scale based on zero degrees for the freezing point of water and 100 degrees for the boiling point of water. Water boils at a lower temperature as you gain altitude (e.g., going higher on a mountain), and boils at a higher temperature if you increase atmospheric pressure (coming back down to sea level or going below it). The fundamental explanation of the process has to do with the fact that in the liquid state, the molecules move constantly and are united to each other by attractive forces. Sigma-Aldrich offers a number of Phenolphthalein products. Since \"grade\" was already in use as a unit of measurement, Celsius was chosen to avoid confusion. Which of the following units is used to measure the weight of a paper? Phenolphthalein Indicator, 1% (w/v) in 95% (v/v) Alcohol, Neutralized, Related Products: Phenolphthalein Indicator, Phenolphthalein can be used in a 1% alcoholic solution as an indicator in titrations of mineral and organic acids and most alkalies. - 263 deg C Decomposition temperature: Not available 500 ml ( 00500 ) it taken... 8.3 and colorless in acidic solutions % ( w/v ), Volumetric volume.Then we say that liquid boils decided standardize...
