naming of acids

For binary compounds with hydrogen as the positive ion, place the term HYDRO at the front of the stem of the negative ion, the letters IC at the end of the stem, and add the word acid.

Examples :

HBr is hydrobromic acid
H2S is hydrosulfuric acid
HF is hydrofluoric acid
H2Te is hydrotelluric acid
HCN is hydrocyanic acid
