Citric acid is also used as a chelating agent in food processing. It binds to metal ions, which can cause oxidation and affect flavor and color. By binding these metals, citric acid helps maintain the stability and quality of food products, preserving their appearance and taste. This property is especially useful in products like canned vegetables and fruits, where maintaining color is vital for consumer appeal.

The production of sodium bicarbonate typically involves the Solvay process, which utilizes sodium chloride (table salt), ammonia, and carbon dioxide. The cost of sourcing raw materials is a significant component of the overall price. Fluctuations in the prices of these raw materials directly affect sodium bicarbonate's market price. For instance, any variation in ammonia costs can lead to changes in production costs, ultimately impacting end-user prices.

Despite its benefits, aluminum hydroxide is not without potential side effects. Some dogs may experience gastrointestinal issues such as diarrhea, constipation, or an upset stomach after taking this medication. Long-term use of aluminum hydroxide as a phosphate binder can also lead to aluminum toxicity, especially in cases where the dog has impaired renal function. Symptoms of aluminum toxicity can include lethargy, bone pain, and neurological problems.
