Sulfuric acid (H2SO4) is a strong acid which should be neutralized with a base. Ideally, sodium bicarbonate (NaHCO3) is used to treat acid spills. The reaction is as follows:

H2SO4 + 2NaHCO3 → Na2SO4 + 2H2O + 2CO2

Bubbles will be formed as CO2 is released. Once all H2SO4 has been neutralized the bubbles will stop. The pH of the spill after neutralization can be checked with a pH and should be between 6-9. If optimal pH is observed the waste can be disposed into a proper container and the work station can be cleaned with a paper towel.
