Question

What salt is produced in each of the following neutralization reactions?

a) NaCl
b) K₂SO₄
c) Mg(OH)₂
d) CaCO₃

Answer 1

Balanced chemical equations show the formation of BaSO4, MgSO3, PbSO4, and AgCl from their respective neutralization reactions, indicating the types of salts produced.

Step-by-step explanation:

To find out what salt is produced in each of the specified neutralization reactions, we need to write balanced chemical equations. Here are the balanced reactions for the given scenarios:

1. BaSO4: Barium sulfate is produced by the reaction between barium hydroxide and sulfuric acid or barium metal and sulfuric acid.
   Ba(OH)2(aq) + H2SO4(aq) → BaSO4(s) + 2H2O(l)
   
   Ba(s) + H2SO4(aq) → BaSO4(s) + H2(g)
2. MgSO3: Magnesium sulfite is produced by the reaction of magnesium hydroxide with sulfurous acid (SO3 dissolved in water is sulfurous acid):
   Mg(OH)2(s) + SO3(g) → MgSO3(s) + H2O(l)
3. PbSO4: Lead(II) sulfate is produced by the reaction of lead(II) nitrate with sulfuric acid:
   Pb(NO3)2(aq) + H2SO4(aq) → PbSO4(s) + 2HNO3(aq)
4. AgCl: Silver chloride is produced by the reaction of silver nitrate with hydrochloric acid:
   AgNO3(aq) + HCl(aq) → AgCl(s) + HNO3(aq)

The products of these reactions are the salts listed, and the hydrogen and hydroxide from the acid and base, respectively, combine to form water, displaying the nature of a neutralization reaction.
