Calcium is an active metal and its carbonate when, Made to react with hydrochloric acid or rather any strong acid gives an effervescence of carban dioxide gas. The anion of acid that in this case is chloride ion makes salt with metal by displacing its weaker anion. ...
What does a travertine rock look like? Travertine often hasa fibrous or concentric appearanceand exists in white, tan, cream-colored, and even rusty varieties. It is formed by a process of rapid precipitation of calcium carbonate, often at the mouth of a hot spring or in a limestone cave....
Recrystallization: Recrystallization is when a substance is dissolved so that it can be purified in a hot liquid. When the solvent cools down, the solution is saturated with the solute that crystalizes, or forms a solid again. Carbonate minerals can recrystallize due to their structure. ...
like gold and platinum-group metal do not react with nitric acid, though pure gold does react withaqua regia, a mixture of concentrated nitric acid and hydrochloric acid. However, some less noble metals like silver or copper can be easily dissolved by nitric acid. Therefore nitric acid ...
