select all of the following that are salts.\n□ nacl\n□ nh₃\n□ (nh₄)₂so₄\n□ nh₄cl\n□ h₂so₄\n□ nano₃\n□ nh₄oh

Answer

Explanation:

Step1: Recall salt definition

A salt is a compound formed by the reaction of an acid and a base, consisting of a cation (positive - ion) and an anion (negative - ion).

Step2: Analyze each compound

  • $\ce{NaCl}$: Formed from $\ce{HCl}$ and $\ce{NaOH}$, has $\ce{Na+}$ cation and $\ce{Cl-}$ anion, is a salt.
  • $\ce{NH3}$: Ammonia is a base, not a salt.
  • $\ce{(NH4)2SO4}$: Formed from $\ce{H2SO4}$ and $\ce{NH3\cdot H2O}$, has $\ce{NH4+}$ cations and $\ce{SO4^{2 - }}$ anions, is a salt.
  • $\ce{NH4Cl}$: Formed from $\ce{HCl}$ and $\ce{NH3\cdot H2O}$, has $\ce{NH4+}$ cation and $\ce{Cl-}$ anion, is a salt.
  • $\ce{H2SO4}$: Sulfuric acid, not a salt.
  • $\ce{NaNO3}$: Formed from $\ce{HNO3}$ and $\ce{NaOH}$, has $\ce{Na+}$ cation and $\ce{NO3-}$ anion, is a salt.
  • $\ce{NH4OH}$: Ammonium hydroxide is a base, not a salt.

Answer:

$\ce{NaCl}$, $\ce{(NH4)2SO4}$, $\ce{NH4Cl}$, $\ce{NaNO3}$
