Answer

Explanation:

Step1: Recall limestone - acid reaction

Limestone is mainly calcium carbonate ($CaCO_3$). In acidic water, it reacts with hydrogen ions ($H^+$). The reaction is $CaCO_3 + 2H^+ \rightarrow Ca^{2+}+H_2O + CO_2\uparrow$.

Step2: Consider temperature effect

Warmer water can hold less carbon - dioxide. As the reaction produces carbon - dioxide, the increased temperature can drive the reaction forward.

Answer:

The limestone precipitation would dissolve more readily as the acidic water reacts with the calcium carbonate in limestone, and the warmer temperature can further promote the reaction by reducing the solubility of carbon - dioxide in water.
