Write the correct chemical formula to distinguish between?….. calcium sulfide and calcium hydrogen sulfide
February 20th, 2023
##CaS##, ##”calcium sulfide………”##
##Ca(HS)_2##, ##”calcium hydrogen sulfide………”##
Calcium forms a ##Ca^(2+)## ion, and thus requires 2 negative charges to form a neutral salt. The salts of ##H_2S## could be sulfides, ##S^(2-)##, or hydrogen sulfides, ##HS^(-)##.
