dissociation NaCH3COO*3H2O
CH3COONa.3H2O ==> CH3COO^-(aq) + Na^+(aq) + 3H2O
The dissociation of NaCH3COO*3H2O can be explained step-by-step:
Step 1: Write down the chemical formula of the compound.
The compound is sodium acetate trihydrate, and its chemical formula is NaCH3COO*3H2O.
Step 2: Identify the ions present in the compound.
The compound contains sodium ions (Na+) and acetate ions (CH3COO-).
Step 3: Separate the ions.
When NaCH3COO*3H2O dissociates, it releases the sodium ions and the acetate ions. The water molecules remain as part of the compound.
So, the dissociation of NaCH3COO*3H2O can be represented as follows:
NaCH3COO*3H2O (s) → Na+ (aq) + CH3COO- (aq) + 3H2O (l)
Please note that the (s) and (l) notations indicate the physical states - solid and liquid, respectively. The (aq) notation indicates that the ions are dissolved in water.
The dissociation of NaCH3COO·3H2O involves breaking apart the compound into its respective ions when it is dissolved in water. In this case, NaCH3COO·3H2O dissociates into sodium ions (Na+), acetate ions (CH3COO-), and water molecules (H2O).
To calculate the dissociation of NaCH3COO·3H2O, we need to write down the balanced chemical equation for the dissociation. The formula for sodium acetate trihydrate is NaCH3COO·3H2O, and when it dissolves in water, it breaks apart into its ions:
NaCH3COO·3H2O (s) → Na+ (aq) + CH3COO- (aq) + 3H2O (l)
This equation shows that one formula unit of NaCH3COO·3H2O dissociates into one Na+ ion, one CH3COO- ion, and three H2O molecules.
The sodium ion (Na+) and acetate ion (CH3COO-) formed from the dissociation are both soluble in water. They will exist as separate entities in the resulting solution.
Additionally, the three water molecules (H2O) that are released in the process remain in the liquid state as individual water molecules.
It's important to note that the presence of water molecules in the compound NaCH3COO·3H2O does not affect the dissociation process. In water, the compound dissociates into its ions regardless of the presence of water molecules within the crystal structure.
