Živa(II) sulfat je hemijsko jedinjenje sa formulom Hg S O₄. To je bezbojna čvrsta materija koja formira bele granule ili kristalni prah. U vodi se razdvaja kao nerastvorni sulfat žute boje i sumporna kieselina.^[5]

Proizvodnja

Živa sulfat, HgSO₄, se može formirati na dva načina:

Zagrevanjem koncentrovane H₂SO₄ se elementarnom živom:^[6]

Hg + 2 H₂SO₄ → Hg(SO₄) + SO₂ + 2 H₂O

Ili, rastvaranjem čvrstog žutog živa oksida u koncentrovanoj sumpornoj kiselini i vodi.^[7]
