Detailed explanation-1: -What is Hydroxide? OH− is a diatomic anion with the chemical name Hydroxide. Hydroxide is also called Hydroxyl or Hydroxyl radical or hydroxide ion. It consists of hydrogen and an oxygen atom which are held together by a covalent bond.
Detailed explanation-2: -The hydroxide ion consists of a single oxygen and single hydrogen atom bonded together, sharing two electrons and has a negative charge on the oxygen. The formula for a hydroxide ion is OH− O H − .
Detailed explanation-3: -It’s written in “reverse order” because hydroxide is a polyatomic ion that still needs balance to be part of a compound. In most cases, when OH bonds to another ion the oxygen is the one that bonds to the other ion. Because of this it’s is written as OH, so that it will be easier to tell how the molecule is bonded.
