Answer:
B. Household ammonia.
Explanation:
NH₃ is a base, so the solution always will be basic.
NH₃ takes the proton from the water. In conclusion we have free OH⁻ in medium, that's why the solution is basic.
NH₃ + H₂O → NH₄⁺ + OH⁻
- HCl + H₂O → H₃O⁺ + Cl⁻
This reaction makes an acid solution, cause the H₃O⁺
- Vinegar is a compound made of acetic acid.
CH₃COOH + H₂O ⇄ H₃O⁺ + CH₃COO⁻
This reaction also makes an acid solution, cause the H₃O⁺
- Pure water makes neutral solution. It is not acid, neither basic.
2H₂O ⇄ H₃O⁺ + OH⁻
