Answer:
Formula for sodium hydroxide is represented by NaOH.
Step-by-step explanation:
The reaction of Sodium oxide with water is as follow,
Na₂O + H₂O → 2 NaOH
Na₂O is considered as a strong basic oxide as it contains O²⁻ which has high tendency to bind with hydrogen atoms. This reaction is an exothermic reaction and is conducted in cold water to produce NaOH.
