  3.2 Acid reaction:
• KHSO₄ + NaOH -> –> NaHSO₄ + H₂O ->
• KHSO₄ + KOH -> –> K₂SO₄ + H₂O ->
  3.3 Nonmetal reaction:
• KHSO₄ + H₂O -> –> K₂SO₄ + 2H₂O ->
• KHSO₄ + Cl₂ -> –> KCl + H₂SO₄ ->

4. Synthesis of KHSO₄:

4.1 Laboratory synthesis of KHSO₄: KHSO₄ can be synthesized from the reaction of K₂SO₄ with H₂SO₄.

• K₂SO₄ + H₂SO₄ -> –> 2KHSO₄

4.2 Industrial synthesis of KHSO₄: In industry, KHSO₄ is typically produced by reacting K₂SO₄ with H₂SO₄ at high temperatures.
