Final answer:
The reaction between sulfuric acid and potassium hydroxide is an acid-base reaction option (a), typically resulting in the formation of salt and water. Other reactions can include redox, precipitation, and decomposition, depending on the reactants and products involved.
Step-by-step explanation:
When sulfuric acid reacts with potassium hydroxide, it undergoes an acid-base reaction. This type of reaction is also known as a neutralization reaction, where an acid and a base react to form a salt and water. In this case, the products are potassium sulfate and water.
Looking at other examples:
- (b) 2KClO3(s) → 2KCl(s) + 3O2(g) is a decomposition and redox reaction because potassium chlorate decomposes upon heating to potassium chloride and oxygen gas, involving a change in oxidation states.
- (d) Pb(NO3)2(aq) + H2SO4(aq) → PbSO4(s) + 2HNO3(aq) is a precipitation reaction as it results in the formation of a solid, lead sulfate, from two aqueous reactants.
