Bakar(I) sulfid je bakar sulfid, hemijsko jedinjenje bakra i sumpora. Njegova hemijska formula je Cu₂S. On se nalazi u prirodi u mineralu halkocitu. On ima uzak stehiometrijski opseg od Cu_1.997S do Cu_2.000S.^[6].

Priprema i reakcije

Cu₂S se može pripremiti jakim zagrevanjem bakra u sumpornoj pari ili H₂S^[5]. Reakcija bakarnog praha u istopljenom sumporu brzo proizvodi Cu₂S, dok je kuglicama bakra potrebna mnogo viša temperatura.^[7] Cu₂S reaguje sa kiseonikom da formira SO₂:^[8]

2Cu₂S 3O₂ → 2Cu₂O 2SO₂

U proizvodnji bakra dve trećine istopljenog bakar sulfida se oksiduje na gornji način, a Cu₂O reaguje sa neoksidovanim Cu₂S da formira Cu metal:^[8]

Cu₂S 2Cu₂O → 6Cu SO₂
