Question
Based on the amphoteric nature of water, which of the following compounds in which water would act as an acid upon reaction?Question 12Select one:A.Ca(OH)2B.All of the optionsC.NaOHD.NH3
Solution
The amphoteric nature of water means it can act as both an acid and a base. When water acts as an acid, it donates a proton (H+) to a base.
Looking at the options:
A. Ca(OH)2 - This is calcium hydroxide, a strong base. Water would not act as an acid with this compound because it would not need to donate a proton.
B. All of the options - This cannot be the answer because we've already established that water would not act as an acid with Ca(OH)2.
C. NaOH - This is sodium hydroxide, another strong base. Again, water would not act as an acid with this compound.
D. NH3 - This is ammonia, a weak base. Water could donate a proton
