Key Differences
Baking soda, scientifically known as sodium bicarbonate (NaHCO3), is a white crystalline powder commonly used as a leavening agent in baking. It reacts with acidic components in recipes, releasing carbon dioxide and causing dough or batter to rise. Washing soda, or sodium carbonate (Na2CO3), is a more potent alkali and is mainly used for cleaning purposes. It is effective in removing grease, oil, and stains from fabrics and surfaces.
In terms of pH level, baking soda is milder, making it safe for cooking and gentle cleaning tasks, like removing odors from refrigerators or freshening carpets. Washing soda, with a higher pH, is a stronger cleaning agent. It is often used in laundry detergents to enhance cleaning power and remove hard water minerals.
Baking soda has a variety of uses beyond cooking, including as a deodorizer, mild abrasive for cleaning, and ingredient in homemade health and beauty products. Washing soda, due to its caustic nature, is more limited to household cleaning tasks. It's used in heavy-duty cleaners, grease cutters, and as a descaling agent.
The chemical composition of baking soda makes it suitable for consumption in small amounts, as it is non-toxic. Washing soda, however, is not edible and can be harmful if ingested. It requires careful handling, especially when used in concentrated forms.
Baking soda can neutralize acids, making it useful for soothing indigestion or heartburn. Washing soda, on the other hand, can soften hard water, making it useful in areas with mineral-rich water. It can effectively remove build-up from laundry and dishwashers.
