Copper reacts with cold and dilute nitric acid to yield copper nitrate, water and nitric oxide. This is a rather unusual reaction between a metal and an acid, since copper is less reactive than hydrogen on the reactivity series, and so … Solutions of barium chloride and sodium sulphate in water react Es importante mencionar que la reacción en los productos existen dos nitrógenos, el Cu(NO 3) 2 sin embargo éste no llevará coeficiente, pues usaremos al … Молекулярное уравнение реакции имеет вид: HNO3 đặc nguội thì Fe, Al và Cr không phản ứng. Encuentra respuesta a tu tarea ahora en "Tareas Gratis". 硝酸銅是銅(II)的硝酸鹽，化學式為Cu(NO3)2。無水物和水合物都是藍色晶體，但性質有很大不同。水合硝酸銅常用於在學校中演示原電池反應。 Khi cho KL vào HNO3 đặc (riêng Fe, Al và Cr ngoài đk axit đặc còn phải đun nóng) luôn cho NO2. However, nitric oxide is produced with dilute nitric acid, but it can still become nitrogen dioxide when in contact with oxygen gas.
