In summary, when sodium acetate is dissolved in water, it dissociates into sodium ions (Na⁺) and acetate ions (CH₃COO⁻). This process is endothermic, meaning it absorbs heat from the surroundings, which can lead to a decrease in temperature of the solution. The acetate ions can also participate in acid-base reactions in the water, acting as a weak base. Overall, the reaction contributes to the solution's conductivity and alters its pH.

Removes a 'proton' from the water molecule. You might think of it like, CH3COO-is the anion of a weak acid and Na+ is the cation of a strong base. Sodium acetate dissolved in water would if conc. is high enough, make the solution alkaline.

Congratulations, you just discovered process of hydrolysis 
Yes, that's what is happening:
CH3COO- + H2O ↔ CH3COOH + OH-
You might want to read on Brønsted–Lowry acid–base theory, this reaction is an important part of it.

0.01M solution of sodium acetate has a calculated pH of 8.4, you don't need high concentrations for the effect to be easily observable.

Some fading of precise knowledge has been happening the last several years. (That is, in my knowledge)Borek said:
FAQ: How does Sodium acetate react with water?
How does Sodium acetate react with water?
When sodium acetate is added to water, it dissociates into sodium ions and acetate ions. The sodium ions remain in solution while the acetate ions react with water molecules to form acetic acid and hydroxide ions.
Is the reaction between Sodium acetate and water exothermic?
Yes, the reaction between sodium acetate and water is exothermic. This means that it releases heat energy as the reaction proceeds.
What are the products of the reaction between Sodium acetate and water?
The products of the reaction between sodium acetate and water are acetic acid and hydroxide ions.
Does Sodium acetate dissolve in water?
Yes, sodium acetate is highly soluble in water. When added to water, it readily dissolves to form a clear solution.
What is the pH of the solution formed by mixing Sodium acetate with water?
The pH of the solution formed by mixing sodium acetate with water is slightly basic due to the presence of hydroxide ions produced during the reaction.
