← ScienceWhich risk increases when using deionized water in steel piping?
A)Accelerated galvanic corrosion occurs✓
B)Passivation layer formation slows
C)Water hardness increases rapidly
D)Erosion corrosion rate declines
💡 Explanation
Galvanic corrosion accelerates because the **dissociation** of water creates H+ and OH- ions; therefore, with impurities severely limited via deionisation forming hydroxide electrolytes, electrons flow between cathodic and anodic sites is optimized promoting oxidation, rather than restricted as with a robust oxide.
