NaOH is the chemical formula which represents the lye correctly.
Answer: Option D
Explanation:
Lye is termed for molecules made up of metal hydroxide family. As the compound is a metal hydroxide, it should be a base and an alkali according to the properties of metal and OH group. Mostly lye is obtained by leaching ashes or derived from strong alkali metal hydroxides.
So among the given choices, NaOH is the correct option as it is the chemical formula for sodium hydroxide. It is well known that sodium hydroxide is one of the efficient base metal in the alkali group and they can be also termed as caustic soda. Thus NaOH is the chemical formula which represents the lye correctly.
