Answer:
The solid base among the choices is NaOH (sodium hydroxide).
Step-by-step explanation:
A solid base is a substance that can promptly acknowledge protons (H+ particles). Among the given choices:
- НСI (hydrogen cyanide) is certainly not a base.
- NaOH (sodium hydroxide) is areas of strength for a.
- NH3 (smelling salts) is a feeble base.
- H3CO3 (carbonic corrosive) is certainly not a base; it's really a corrosive.
Thus, NaOH is serious areas of strength for the in light of the fact that it separates totally in water to create hydroxide particles, making it a solid salt.
