Question

which ion is characteristic of all acids in water?
oh - (hydroxide ion)
h + (hydrogen ion)
na + (sodium ion)
cl - (chloride ion)

Explanation:

According to Arrhenius theory, acids in water dissociate to produce hydrogen ions (\(H^+\)). Hydroxide ions (\(OH^-\)) are characteristic of bases. Sodium (\(Na^+\)) and chloride (\(Cl^-\)) ions are not specific to all acids.

Answer:

H + (hydrogen ion)
