Is sodium chloride the same as sodium hydroxide?
No they are not. For starters, their names are different. Secondly, in one molecule of sodium chloride (NaCl), there is one atom of sodium to each chloride atom. In sodium hydroxide (NaOH), there is one sodium atom, one oxygen atom, and one hydrogen atom. Sodium chloride is known as salt, and sodium hydroxide is known as lye, or caustic soda.
