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:
1. What happens when sodium acetate is dissolved in water?
When sodium acetate is dissolved in water, it dissociates into sodium ions (Na+) and acetate ions (CH3COO-). This process is typically exothermic, releasing heat into the surrounding solution, which results in an increase in temperature of the solution.
2. Does sodium acetate change the pH of water?
Yes, sodium acetate can alter the pH of water. Being the salt of a weak acid (acetic acid) and a strong base (sodium hydroxide), it acts as a basic buffer. When dissolved, it slightly increases the pH of the solution, making the water more basic.
3. Can sodium acetate react chemically with water itself?
No, sodium acetate does not chemically react with water. Instead, it simply dissolves and dissociates into its constituent ions. There is no chemical reaction involving the breaking or forming of covalent bonds with water molecules.
4. What is the solubility of sodium acetate in water?
Sodium acetate is highly soluble in water. At room temperature (25°C), about 76 grams of sodium acetate can dissolve in 100 milliliters of water. Its solubility increases with temperature, making it even more soluble in hot water.
5. Are there any visual changes when sodium acetate dissolves in water?
There are typically no dramatic visual changes when sodium acetate dissolves in water, as it is a colorless and odorless salt. The solution may become slightly warmer due to the exothermic nature of the dissolution process, but visually, it remains clear and transparent.
