Which of the following is the correct chemical formula for the hydronium ion?
A
OH^-
B
H3O^+
C
NH4^+
D
HCO3^-
Verified step by step guidance1
Understand that the hydronium ion is formed when a water molecule (H2O) gains an extra proton (H+).
Recognize that adding a proton (H+) to H2O results in H3O+, which carries a positive charge.
Recall the chemical formula for the hydroxide ion is OH-, which is different from hydronium.
Note that NH4+ is the ammonium ion, and HCO3- is the bicarbonate ion, both distinct from hydronium.
Conclude that the correct chemical formula for the hydronium ion is \(H3O^{+}\).
