is NaH2CO3 soluble and separate into Na+ and H2CO3- ions?
To determine if NaH2CO3 is soluble and if it separates into Na+ and H2CO3- ions, we can analyze the compound and use solubility rules.
NaH2CO3 is the chemical formula for sodium bicarbonate, also known as baking soda. It is composed of sodium ions (Na+) and bicarbonate ions (H2CO3-).
To determine its solubility, we need to consider the solubility rules for common ionic compounds:
1. Most sodium (Na+) compounds are soluble, meaning they will dissolve in water.
2. Most bicarbonate (HCO3-) compounds are also soluble.
Therefore, based on these solubility rules, NaH2CO3 is soluble in water.
When it dissolves in water, NaH2CO3 will dissociate into its component ions, Na+ and H2CO3-. This is due to the strong attraction between the positively charged sodium ion (Na+) and the negatively charged bicarbonate ion (HCO3-). The dissociation can be represented by the following equation:
NaH2CO3 (s) → Na+ (aq) + H2CO3- (aq)
In water, the sodium ions (Na+) and bicarbonate ions (H2CO3-) will be surrounded by water molecules (hydration), making them indistinguishable and allowing them to move freely in the solution.
