Sodium carbonate contains sodium ions, Na+ and carbonate ions, CO32-
All compounds with the sodium ion are soluble and will dissolve forming ions.
The dissociation reaction (the reaction showing an ionic substance dissolving into its ions) is:
Na2CO3 -->2Na+(aq) + CO32-(aq)

Why is Na2CO3 alkaline in nature?
Because it contains sodium cations, which are strongly basic, and carbonate anions which are weakly acidic. So the basic ions win over acidic ions, making Na2CO3 alkaline(i.e. basic).
A solution of sodium carbonate Na2CO3 that has a molarity of 0.0100 M contains equivalents of sodium ions per liter of the solution?
0.01 mole
How many ions does a metal have?
Metals are not discrete molecules therefore they have an infinite amount of ions essentially. The bigger the metal is the more ions it contains.
Is Na2CO2 ionic or covalent compound?
Na2CO3 is an ionic compound. However, note that it contains covalently bonded carbonate ions, which are not compounds because they are not electrically neutral.
Does a solution of ammonia contain mostly ammonia molecules or mostly ammonium ions and hydroxide ions?
It contains more ammonia molecules because ammonia is only a weak base.

What is the compound Na2CO3 name?
Na2CO3 contains two sodium ions and one carbonate ion. The naming rules dictate that the anion in always written second, and the number of each ion is omitted. Thus, this compound is sodium carbonate.
Is Na2CO2 ionic or covalent compound?
Na2CO3 is an ionic compound. However, note that it contains covalently bonded carbonate ions, which are not compounds because they are not electrically neutral.
Does a solution of ammonia contain mostly ammonia molecules or mostly ammonium ions and hydroxide ions?
It contains more ammonia molecules because ammonia is only a weak base.
Why there are no molecules in ionic compound?
Ionic compounds contain ions, there are no neutral molecules. These are often charged atoms as in NaCl but may be polyatomic ions such as NH4+ which contains covalent bonds
How many moles of ions are produced by the dissociation of 0.5 mol of Na2CO3?
1.5 moles
What materials would be present in a calcium and chloride solution after it has dissolved in water?
It contains Ca2+ ions Cl- ions and water molecules . The word material is not used for ions . The word material often used for solids
What differentiates molecules from ions?
Molecules are electrically neutral. Ions have electric charges.
How do ions become molecules?
Ions and molecules are the results of two different types of bonds. Ions are the result of ionic bonds and molecules are the result of covalent bonds.
What is a substance containing molecules and ions?
Water: H2O molecules, H+ and OH- ions
