Question
Which one is a normal salt?
- Na2SO4
- NaHSO4
- NaHCO3
- Pb(OH)Cl
Answer
Na2SO4
Explanation
Na2SO4 (sodium sulfate) is a normal salt because it is derived from a strong base (NaOH) and a strong acid (H2SO4) and does not have acidic or basic properties. The other compounds are either acidic or basic salts. NaHSO4 (sodium bisulfate) and NaHCO3 (sodium bicarbonate) are acidic salts because they are derived from a weak base (NaHCO3) and a strong acid (H2SO4) or a weak acid (H2CO3) and a strong base (NaOH), respectively. Pb(OH)Cl (lead(II) hydroxychloride) is a basic salt because it is derived from a strong base (NaOH) and a weak acid (HCl).
