Sodium bicarbonate, a white alkaline powder that is easily soluble in water, begins to act after combining with water to release carbon dioxide CO2, which reacts faster in acidic liquids (such as fruit juice), and the effect of releasing gas becomes faster as the ambient temperature increases.
Sodium bicarbonate will remain sodium carbonate after the action, and too much use will give the finished product an alkali taste.
1. Chemical Properties
• Weak Alkalinity: Sodium bicarbonate (baking soda) exhibits weak alkalinity when dissolved in water, with a pH value of approximately 8-9. It is capable of neutralizing acidic substances.
• Thermal Stability: It is relatively stable at room temperature but gradually decomposes when heated above 60°C, forming sodium carbonate, water, and carbon dioxide gas. This property makes it useful as a leavening agent in baking.
• Reactivity: When it reacts with acids, it rapidly releases carbon dioxide gas. This reaction is commonly utilized as a leavening agent in baked goods or as a cleaning agent for stain removal.
2. Physical Properties
• Appearance: It is typically a white crystalline powder with a fine texture, odorless, and has a slightly salty taste.
• Solubility: It is highly soluble in water, with its solubility increasing as the temperature rises.
• Stability: It is stable in a dry environment but tends to clump when exposed to moisture.
3. Production Processes
1. Synthesis Method: Sodium bicarbonate is primarily produced using the Hou's process (Hou Debang method). This method uses table salt (sodium chloride), and carbon dioxide as raw materials. Is first introduced into saturated brine, followed by carbon dioxide, resulting in the formation of sodium bicarbonate crystals. The product is obtained through filtration, washing, and drying.
2. Purification: During the production process, impurities are removed through multiple washings and filtrations to ensure the purity and quality of the product.
