None - because H represents hydrogen - which all acids have, as an acid is a hydrogen ion combined with a base. but there must be other atoms involved and 50 does not represent any other chemical. Maybe you mean H2 SO4 which is sulphuric acid

At school a favourite poem went.
.
Dead and gone is Johnnie,
His face we'll see no more,
For what he thought was H2o
Was H2So4
