Determination of sulfuric acid concentration is very similar to titration of hydrochloric acid although there are two important diferences First of all as sulfuric acid is diprotic stoichiometry of the neutralization reaction is not 1:1 but 1:2 (1 mole of acid reacts with 2 moles of sodium hydroxide)

Since 2004 the ACGIH TLV for sulfuric acid of 0 2 mg/m 3 has carried with it a 'T' endnote indicating that this TLV applied to the portion of the mist being sampled capable of penetrating the pulmonary tract into (and beyond) the Thoracic region This lower TLV (as opposed to the OSHA PEL of 1 0 mg/m 3) is based on the theory that the farther a substance can penetrate into the respiratory
