14 Ιουλ 2023 · The liquid form of sodium hydroxide is devoid of color and scent. The substance exhibits a high degree of reactivity toward both strong acids and water. Table of Contents. Physical Properties of Sodium Hydroxide. Chemical Properties of Sodium Hydroxide. (1) Precipitation Reactions. (2) Addition Reaction With Carbon monoxide (CO) (3) Basic Nature.
The hydroxide ion makes sodium hydroxide a strong base which reacts with acids to form water and the corresponding salts, e.g., with hydrochloric acid, sodium chloride is formed: NaOH(aq) + HCl (aq) → NaCl (aq) + H 2 O ( l )
26 Ιουν 2024 · Highly soluble in water, forms a heat-generating solution: Melting Point: 318°C (604°F) Boiling Point: 1,388°C (2,530°F) Density: 2.13 g/cm³ at 20°C (68°F) pH: Very high, typically around 14 when in solution: Thermal Stability: Stable up to its melting point but decomposes upon heating above
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
