I-sulfuric acid ejiyile (H₂SO₄, amaphesenti angu-96 ngesisindo), yisenzi esinamandla sokususa amanzi ne-asidi eqinile esetshenziswa ekwenziweni kwempushana yombala, ekuhlanzeni insimbi nge-asidi, nasezimweni zamakhemikhali ezidinga i-asidi engahwamuki. Idla kakhulu futhi ikhipha ukushisa okukhulu uma ixutshwa namanzi — NJALO faka i-asidi emanzini, ungalokothi ufake amanzi kwi-asidi.
