  1. Sodium Hydroxide | NaOH or HNaO | CID 14798 - structure, chemical names, physical and chemical properties, classification, patents, literature, biological activities, safety/hazards/toxicity information, supplier lists, and more.

  2. It melts congruously at 7.55 °C into a liquid with 35.7% NaOH and density 1.392 g/cm 3, and therefore floats on it like ice on water. However, at about 4.9 °C it may instead melt incongruously into a mixture of solid NaOH·3.5H 2 O and a liquid solution.

  3. 14 Ιουλ 2023 · At a temperature of 20 °C, the solubility of sodium hydroxide (NaOH) in water is 109 grams per 100 grams of water. Additionally, the heat of solution for this process is -44.5 kJ mol -1 (kilojoules per mole).

  4. C p ° = A + B*t + C*t 2 + D*t 3 + E/t 2 H° − H° 298.15 = A*t + B*t 2 /2 + C*t 3 /3 + D*t 4 /4 − E/t + F − H S° = A*ln(t) + B*t + C*t 2 /2 + D*t 3 /3 − E/(2*t 2 ) + G

  5. Physical Properties. As a solid, sodium hydroxide is colorless, odorless, and features a crystalline structure. When dissolved in water or neutralized with acid it liberates substantial heat, which can be dangerous. 1 Its melting point is 318°C, and it has a boiling point of 1388°C.

    29 Ιουλ 2024 · Our boiling point calculator uses the Clausius–Clapeyron relation to establish the boiling point of any substance at a given pressure. This equation characterizes phase transitions (such as vaporization) and relates the pressure to boiling point in the following way: ln(P₁/P₂) = -ΔH/R × (1/T₁ − 1/T₂) where: P₁ — Pressure at ...

  7. 18 Νοε 2023 · Sodium hydroxide, sometimes called caustic soda, is a strongly basic inorganic compound with chemical formula NaOH. It is a hygroscopic white solid with a variety of uses, such as in double replacement reactions to form metal hydroxides or oxides.
