HClO 4 + NaOH = NaClO 4 + H 2 O is a neutralization reaction (also a double displacement reaction). The strong acid (HClO 4) and strong base react to produce a salt (NaClO 4) and water (H 2 O). To balance net ionic equations we follow these general rules: Write the balanced molecular equation. Write the state (s, l, g, aq) for each substance Thermal stability: H OC l <H C lO2 <H C lO3 < H C lO4 . Acid with higher oxidation number is more capable of oxidising other species. Higher the oxidation number more is the acidity. (e) Equal (25%) each Cl-atom is sp3 hybridised

What is the Formal charge on Cl in HClO4? Answer: The formal charge over an atom of a polyatomic molecule or ion is the difference between the valence electron of that atom in the elemental state and the number of electrons assigned to that atom in the Lewis structure.
