Question

what does an oxygen scavenger used in cooling towers affect? choose an option below ph conductivity microbiological growth galvanic action

Explanation:

Oxygen scavengers in cooling towers remove dissolved oxygen. Galvanic action (corrosion from electrochemical cells) relies on oxygen as a cathodic reactant; reducing oxygen directly impairs this process. pH is affected by acid/base chemicals, conductivity by dissolved solids, and microbial growth by biocides, not oxygen scavengers.

Answer:

galvanic action
