Arm & Hammer washing soda and baking soda are two common household products with distinct properties and applications. While both are forms of sodium bicarbonate, they differ in their composition, physical characteristics, and uses. This article delves into the differences between these two substances, exploring their chemical makeup, properties, and practical applications.
What is Arm & Hammer Washing Soda?
Arm & Hammer washing soda, also known as sodium carbonate, is a white, crystalline compound with the chemical formula Na2CO3. It is a strong alkali, with a pH of around 11, and is commonly used as a cleaning agent and water softener.
Chemical Composition and Properties
Washing soda is highly soluble in water, forming an alkaline solution. It is a strong base, capable of neutralizing acids and removing dirt and grease. It also has water-softening properties, as it reacts with calcium and magnesium ions in hard water to form insoluble precipitates, preventing them from interfering with cleaning processes.
Uses and Applications
Washing soda is primarily used for cleaning and laundry purposes. It is effective in removing tough stains, grease, and dirt from various surfaces, including clothing, carpets, and cookware. It is also commonly used as a water softener in regions with hard water, helping to improve the efficiency of detergents and cleaning agents.
What is Baking Soda?
Baking soda, also known as sodium bicarbonate, is a white, powdery substance with the chemical formula NaHCO3. It is a mild alkali, with a pH of around 8.1, and is widely used in baking, cooking, and household cleaning.
Chemical Composition and Properties
Baking soda is a weak base, less alkaline than washing soda. It is soluble in water, forming a slightly alkaline solution. It is also a mild abrasive, making it useful for cleaning and scouring surfaces. Additionally, baking soda has odor-absorbing properties and can be used as a natural deodorizer.
Uses and Applications
Baking soda is primarily used as a leavening agent in baking. When combined with an acidic ingredient, such as lemon juice or buttermilk, it releases carbon dioxide gas, causing baked goods to rise. It is also used as a tenderizer in meat and poultry, helping to break down tough fibers and improve texture. Additionally, baking soda has various household applications, including cleaning, deodorizing, and stain removal.
Composition Differences
The primary difference between washing soda and baking soda lies in their chemical composition. Washing soda is sodium carbonate (Na2CO3), while baking soda is sodium bicarbonate (NaHCO3). This difference in composition results in distinct properties and applications for each substance.
Chemical Composition
Washing soda contains two sodium atoms, one carbon atom, and three oxygen atoms, while baking soda contains one sodium atom, one hydrogen atom, one carbon atom, and three oxygen atoms. The presence of the hydrogen atom in baking soda makes it a weaker base and less alkaline than washing soda.
Properties and Applications
The difference in chemical composition leads to several notable differences in properties and applications. Washing soda is a stronger alkali, with a higher pH and greater ability to neutralize acids and remove dirt and grease. It is also more effective as a water softener. Baking soda, on the other hand, is a milder alkali, making it suitable for use in baking and cleaning tasks where a gentler touch is required.
Physical Properties
Washing soda and baking soda differ in their physical properties as well.
Washing Soda
Washing soda is a white, crystalline solid with a slightly bitter taste. It is highly soluble in water, forming an alkaline solution.
Baking Soda
Baking soda is a white, powdery solid with a slightly salty taste. It is also soluble in water, but to a lesser extent than washing soda, forming a slightly alkaline solution.
Comparison
Washing soda is more soluble in water than baking soda, and its solution is more alkaline. Baking soda has a finer texture and is less abrasive than washing soda.
Uses and Applications
Washing soda and baking soda have distinct uses and applications due to their different properties.
Washing Soda

Baking soda is primarily used as a leavening agent in baking, helping baked goods to rise. It is also used as a tenderizer in meat and poultry, and as a natural deodorizer. Additionally, baking soda has various household applications, including cleaning, deodorizing, and stain removal.
Safety Considerations
Both washing soda and baking soda are generally safe to use, but certain precautions should be taken when handling them.
Washing Soda
Washing soda is a strong alkali and can cause skin irritation and eye damage. It is important to wear gloves and eye protection when handling it. It should also be kept out of reach of children and pets.
Baking Soda
Baking soda is a milder alkali and is generally safe to handle. However, it can also cause skin irritation and eye damage if not handled properly. It is advisable to wear gloves when handling large amounts of baking soda.
Comparison
Washing soda is more hazardous than baking soda due to its stronger alkaline properties. It is important to take appropriate safety precautions when handling both substances.
Availability and Pricing
Washing soda and baking soda are both readily available in most grocery stores and household goods retailers.
Availability
Washing soda is typically found in the laundry detergent section, while baking soda is usually located in the baking aisle.
Pricing
The price of washing soda and baking soda varies depending on the brand and quantity purchased. In general, washing soda is slightly more expensive than baking soda.
Conclusion
Arm & Hammer washing soda and baking soda are two distinct substances with different chemical compositions, properties, and applications. Washing soda is a strong alkali, commonly used for cleaning, laundry, and water softening. Baking soda is a milder alkali, primarily used as a leavening agent in baking, as well as for cleaning, deodorizing, and stain removal. While both substances have their own unique uses and benefits, it is important to understand their differences and handle them safely.
