Which property is shown by the alkali sodium hydroxide?
Which property is shown by the alkali sodium hydroxide?
- A. It has a pH less than pH 7
- B. It produces a gas when it is warmed with ammonium chloride
- C. It turns blue litmus red
- D. It turns Universal Indicator green
Step-by-step solution
Sodium hydroxide (NaOH) is a strong base. When warmed with ammonium chloride (NH4Cl), it undergoes a double displacement reaction producing ammonia gas (NH3), water, and sodium chloride. This is a characteristic property of bases reacting with ammonium salts. Options A, C, and D are incorrect because NaOH is basic (pH>7), turns red litmus blue, and turns universal indicator blue/purple, not green.
