Application	Sodium acetate serves multiple purposes across various industries due to its versatile nature. Primarily, it is used as a buffering agent to maintain consistent pH levels, particularly in the range of 3 to 6, which is essential for stabilizing the pH of certain foods. In the textile industry, sodium acetate is utilized to neutralize sulfuric acid waste streams and acts as a photoresist with aniline dyes, while in the synthetic rubber production, it helps retard vulcanization. For concrete, it functions as an effective and environmentally friendly sealant to protect against water damage. In the food industry, sodium acetate is often added as a seasoning, commonly in the form of sodium diacetate to provide a salt and vinegar flavor, for instance, to potato chips. Additionally, it's a key component in consumer heating pads or hand warmers, where it releases heat upon crystallization. The compound can also participate in chemical reactions, such as forming esters with alkyl halides, showing its broad applicability beyond fundamentals in pH buffering.
