Un higrómetro que para calcular la humedad se vale de la diferencia de temperaturas entre un termómetro con el bulbo seco y otro con el bulbo húmedo, normalmente se denomina psicrómetro.
Explanation:
MgSO₄ + Pb(NO₃)₂ = PbSO₄(s) + Mg(NO₃)₂
Mg²⁺ + SO₄²⁻ + Pb²⁺ + 2NO₃⁻ = PbSO₄ + Mg²⁺ 2NO₃⁻
Pb²⁺ + SO₄²⁻ = PbSO₄
