MHT CET Chemistry Question (2026) — Solution
Options
- A. It is highly water soluble.
- B. It absorbs atmospheric CO _2 to form Na _2 CO _3.
- C. the solution of NaOH turns blue litmus red.
- D. NaOH is a white deliquescent solid.
Answer
C. the solution of NaOH turns blue litmus red.
Step-by-step solution
Sodium hydroxide ( NaOH ) is a strong base. Basic solutions turn red litmus paper blue. Therefore, the statement that the solution of NaOH turns blue litmus red is false. The other statements are true: NaOH is highly soluble in water. It reacts with atmospheric CO _2 to form sodium carbonate ( Na _2 CO _3). It is a white, deliquescent solid that readily absorbs moisture from the air. Answer: the solution of NaOH turns blue litmus red.
