what is the highest freezing point of H2O, NaCl, and HF
To determine the highest freezing point among H2O (water), NaCl (sodium chloride), and HF (hydrogen fluoride), we need to compare their respective freezing points.
Water (H2O) has a freezing point of 0 degrees Celsius or 32 degrees Fahrenheit.
Sodium chloride (NaCl) is a salt and has a much higher freezing point than water. The freezing point of a saturated NaCl solution is around -21.1 degrees Celsius or -6 degrees Fahrenheit.
Hydrogen fluoride (HF) is a highly polar molecule and has an even higher freezing point than NaCl. The freezing point of HF is -83.6 degrees Celsius or -118.5 degrees Fahrenheit.
Therefore, out of the three substances, hydrogen fluoride (HF) has the highest freezing point at -83.6 degrees Celsius or -118.5 degrees Fahrenheit.
To find such information, you can refer to credible scientific sources, chemistry textbooks, or conduct an internet search with the name of the substance and the phrase "freezing point." These sources provide reliable and accurate information on various chemical properties, including freezing points.
