← ScienceWhich outcome occurs when industrial NaCl electrolysis contaminates membrane?
A)Increased electrical resistance develops rapidly✓
B)Platinum catalyst is irreversibly poisoned
C)Hydrogen embrittlement affects downstream pipes
D)Over-chlorination produce dangerous halogens occur
💡 Explanation
Electrical resistance sharply increases when ionic contaminants accumulate in membrane pores, blocking ion flow; this is due to **membrane fouling**, because the membrane's selective transport decreases, therefore cell voltage increases, rather than other chemical processes.
