Fluoride test with acid and the product formed and the properties of the acquired product

HF is the acquired product

it’s not stored in a glass bottle since it reacts with SiO2 to form H2SiF4 and melts it! actually, that’s how also the presence of HF is tested!

Confirmatory test for carbon dioxide reactions and the product acquired

CO2 is treated with Ca(OH)2 or Ba(OH)2 and forms the carbonate salt

also the Ba(OH)2 is also called baryta water
