What additional agent is commonly used with ammoniated citric acid to enhance its effectiveness?

The use of ammoniated citric acid in various applications, particularly in cleaning and maintenance tasks, is enhanced significantly by the addition of sodium nitrate. Sodium nitrate acts as a synergistic agent that improves the overall efficacy of the cleaning solution, primarily by modifying pH and contributing to the removal of rust, scale, and other deposits. This interaction can result in a more potent formulation that can tackle a wider range of contaminants while ensuring that the cleaning process remains efficient.

Sodium nitrate also plays a role in preventing the corrosion of metals during cleaning by providing passivation, which helps protect surfaces after cleaning. This is particularly important in power engineering and industrial applications, where the longevity and integrity of equipment are critical.

In contrast, acetic acid, hydrochloric acid, and chlorine do not enhance ammoniated citric acid in the same synergistic manner. While these substances may have their own applications in cleaning or chemical processes, they do not combine with ammoniated citric acid to improve its effectiveness in the same way that sodium nitrate does.
