Which of the following is the common name of a natural admixture mineral of zinc carbonate and hydrous zinc silicate?

Calamine

The correct answer is option 1. Calamine.

Calamine is a mineral composed of a mixture of zinc carbonate \((ZnCO_3)\) and a hydrous zinc silicate. It typically appears in a pink to white color and is known for its soothing properties, making it useful in various skincare products. The primary components of calamine are zinc oxide \((ZnO)\), which forms from the decomposition of zinc carbonate, and the hydrous zinc silicate.

The name "calamine" is often associated with a pinkish lotion or powder that is derived from this mineral. This calamine lotion has been traditionally used to soothe and relieve skin irritations, such as itching and mild burns. It has anti-inflammatory properties and helps cool and protect the skin.

In summary, calamine is both a mineral and a product derived from it, commonly used for its skin-soothing properties due to the presence of zinc compounds in its composition.
