sulphuric acid
Potassium hydroxide is a strong alkali. Therefore it can be neutralized by using a strong acid such as nitric acid or sulfuric acid.
Actually there are two possibillities:K2SO4, potassium sulfate, when 1 mole sulfuric acid is added to 2 moles potassium hydroxide 2 KOH + H2SO4 ------> K2SO4 + 2 H2OorKHSO4, potassium hydrogen sulfate (-bisulfate), when 1 mole sulfuric acid is added to 1 mole potassium hydroxide 1 KOH + H2SO4 ------> KHSO4 + H2O
2 KOH + H2SO4 --> 2 H2O + K2SO4 Potassium Hydroxide + Sulfuric Acid --> Water + Potassium Sulfate.

Potassium sulfate = K2SO4
2 KOH + H2SO4 --> 2 H2O + K2SO4 Potassium Hydroxide + Sulfuric Acid --> Water + Potassium Sulfate.

Hydrochloric acid Sulfuric acid Phosphoric acid Sodium hydroxide Calcium hydroxide Potassium hydroxide
[2K+]tribunated + 2I-(aq) + Cu2+(aq) + [SO42-]tribunated --> --> CuI2(s) + [2K+ + SO42- ]tribunated
when sulphuric acid is reacted with potassium hydroxide, neutrallisation reaction occurs to form water and potassium sulphate.
2KOH + H2SO4 -> 2H2O + K2SO4
Potassium sulphate and water: H2SO4 + 2 KOH----------K2SO4 + 2H2O
