Which of the following minerals will fizz in contact with hydrochloric acid?

A) quartz
B) calcite
C) fluorite
D) gold

Respuesta :

Calcite is the mineral that fizzes.

A mineral will fizz if it will produce carbondioxide on reaction with HCl

quartz in a mineral of silicon so it will not produce fizz

fluortie is CaF2, so it could not produce CO2 on reaction with HCl

Gold, for sure cannot product CO2


Calcite is CaCO3

it reacts with HCl as

CaCO3  + 2HCl  ===>  CO2(g) (fizz) + CaCl2  + H2O

This is in fact a test for presence of calcite ore
