Select one: a. 0 M solution of KNO 3 in water would be less than 0. 1 g/mL<br />Boiling and Freezing Point: 400°C, 333°C<br />Solubility: Water, Glycerin, and Alcohol<br />Synonyms: Potash Nitrate, Materials that will not burn in air when exposed to a temperature of 820 °C (1,500 °F) for a period of 5 minutes. It is a potassium salt of nitric acid. 0^ Potassium nitrate is a chemical compound with a sharp, salty, bitter taste and the chemical formula KNO3. Nitre, or potassium nitrate, because of its early and global use and production, has many names. 0°C is -0. ChemSpider record containing structure, synonyms, properties, vendors and database links for Potassium nitrate, 7757-79-1, Niter, FGIUAXJPYTZDNR-UHFFFAOYSA-N The freezing points of the solutions arranged from highest to lowest are: LiNO₃ > K₂CO₃ > CoBr₃. (e. Explain how this observation is consistent with what is known about colligative properties. Its solubility curve makes recrystallization easy, being only somewhat soluble in To start solving the problem, identify the given values: the molality m of the solution is 0. Carbon tetrachloride) Avoid dust formation. , Which has the higher boiling point: Explanation To determine which solution has the highest freezing point, we need to consider the concept of freezing point depression, which states that the presence of solute particles Study with Quizlet and memorize flashcards containing terms like Which aqueous solution has the lowest freezing point? 0. 0 M KNO3 b. The freezing point of a 1.
