What happens when sodium acetate is heated?
When a solution of sodium acetate is heated above 58 degrees C, it loses its hydration capacity and dissolves in the resulting steam. The heat of this process is 19.7 kJ / mole (an endothermic process).
What are the solubilities of anhydrous and trihydrate sodium acetate?
Anhydrous sodium acetate is very soluble in water with a solubility of 1190 grammes per litre at 0 deg Celsius. However, the trihydrate is not as soluble and has a solubility of 464 grammes per litre at 20 deg Celsius.
What is the acid dissociation constant of sodium acetate?
When an aqueous solution of sodium acetate is added to a diluted solution of the weak base NaOH, the dissociation of the weak acid from the salt causes hydroxyl ions to be liberated. This causes the solution to become basic as OH- ions are produced.
What is the concentration of hydrogen ions in a 1.0 M solution of a weak acid?
When a 1.0 M aqueous solution of the weak acid is added to a diluted solution of sodium acetate, the dissociation of the weak acid causes hydroxyl ions to be liberated. The hydrogen ion concentration is much less than the molar concentration of the weak acid, so the solution is considered to be basic.
