How Long Does It Take for Phosphoric Acid to React?

Explanation:

The question 'how long to the acid sticks (phosphoric acid) need' appears to be incomplete or contains a typographical error, which makes it difficult to provide a precise answer. Generally, in the context of chemistry, when discussing phosphoric acid and its applications or reactions, it's crucial to provide complete information about the specific use case or the reaction conditions.

The duration of time phosphoric acid requires to react or to be used in a certain process (like cleaning or rust removal) depends on factors like concentration, temperature, and the materials involved. For example, when used in rust removal, phosphoric acid may need several minutes to several hours to react with the rust, depending on the product formulation and the extent of the rust.
