Sodium ______________ has inverted solubility curve i.e. its solubility increases with the lowering of temperature?
Correct answer: A. Carbonate (monohydrate)
- A. Carbonate (monohydrate)
- B. Chloride
- C. Thiosulphate
- D. Bisulphite
Explanation
Sodium carbonate monohydrate shows retrograde or inverted solubility over the relevant temperature range, so cooling can increase its solubility. Sodium chloride and sodium thiosulphate show the usual positive temperature-solubility trend.
