WebAs inorganic salts, sodium hydrosulfide (NaHS) and sulfide (Na2 S) are classic H 2 S donors. NaHS and Na 2 S were the first H 2 S donors to be studied in the cardiac system [80,81]. They have been used extensively to give a short burst of H 2 S. NaHS dissociates to Na + and HS −, and then binds partially to H + to form undissociated H 2 S.
