Na2CO3aq

Na2CO3aq refers to sodium carbonate in an aqueous solution, commonly known as sodium bicarbonate or baking soda. It is a white, crystalline solid that is highly soluble in water, forming a colorless solution. Sodium carbonate is a strong base and a weak acid salt, which means it can react with both acids and bases. In aqueous solution, it dissociates into sodium ions (Na+) and carbonate ions (CO3^2-). The carbonate ions can further react with water to form bicarbonate ions (HCO3-) and hydroxide ions (OH-), making the solution slightly basic.

Na2CO3aq is widely used in various industries, including glassmaking, paper production, and as a pH regulator in water treatment. It is also a common ingredient in household cleaning products and as a leavening agent in baking. In the laboratory, it is used as a titrant in acid-base titrations and as a precipitating agent for various metal ions.

The chemical formula for sodium carbonate is Na2CO3. Its molar mass is approximately 105.99 g/mol. It is non-flammable but can release toxic fumes of carbon dioxide when heated to decomposition. It is also corrosive to metals and tissue. Proper handling and disposal procedures should be followed when working with sodium carbonate solutions.
