Limestone is formed.
Limestone is a sedimentary rock, composed mainly of skeletal fragments of marine organisms such as coral, forams and molluscs. Its major materials are the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO3).
About 10% of sedimentary rocks are limestones. The solubility of limestone in water and weak acid solutions leads to karst landscapes, in which water erodes the limestone over thousands to millions of years. Most cave systems are through limestone bedrock.

Sodium ion when subjected to fire or flame produces yellow flame.
Calcium ions and lithium ions produces red flames.
Potassium ions produces violet or purple flames when put to fire.
The color of the flame of each ion depends on the atomic spectrum of the element.
Thus the answer is Potassium ion.
