How is Zinc bis(hydrogen carbonate) (CAS: 5263-02-5) typically synthesized?

Zinc bis(hydrogen carbonate) is typically synthesized by reacting zinc carbonate with a strong acid such as sulfuric acid or hydrochloric acid. The process involves a stepwise reaction where zinc carbonate is first converted to zinc sulfate or zinc chloride, followed by the formation of zinc bis(hydrogen carbonate) through the addition of water or carbon dioxide. The reaction is carried out under mild conditions, and the product is usually filtered and dried.
