    yes. calcium hydroxide is more desirable than limestone.

    it is because calcium hydroxide is soluble in water . it will

    react with the acidic soil. but the limestone is insoluble

    in water.

    calcium hydroxide is a weak alkali

    it is only slightly soluble in water

    CaO is even better than Ca(OH)2 (although it's out of the scope of this question)

    CaO reacts with water, dissolves faster than Ca(OH)2
