![]() ![]() Too low for the temperature rise to be a concern, however, as the concentration of acid increases above about 1% the temperature rise is not only measureable but can be of concern.įor example, neutralizing a 10% solution of sulfuric acid will yield a temperature rise of nearly 30 0C while neutralizing a 93% solution of concentrated sulfuric will yield a temperature rise of over 150 0C. In most practical applications the acid concentration is Of Ca(OH) 2 (lime) as lime is also two normal:Īll pH neutralization reactions are exothermic and heat will be released. One mole of sulfuric acid will neutralize two moles of sodium hydroxide, as follows:Ĭonversely one mole of sulfuric acid will neutralize one mole Sulfuric acid is a two normal solution which means that for each mole of sulfuric two moles of H+ or acid are liberated packing twice the punch thanĪn equivalent molar concentration of hydrochloric acid, for example. Sulfuric acid is typically used in concentrations ranging from 25% to 96%. Unless calcium is abundantly present this is not an issue. If calcium is present then calcium sulfate (CaSO 4), also known as gypsum, will precipitate. Although adverse reactions are always a possibility, they are rare. It is easier and safer to use than HCl or HNO 3 and is more potent than all of the other acids except for phosphoric. Sulfuric acid is used almost universally for neutralization reactions. Available in concentrations ranging fromĪlso the least expensive acid to use as a neutralizing agent. Sulfuric Acid H 2SO 4: The most widely used and produced chemical in the world. ![]()
