How does copper oxide and sulphuric acid react to
Mixing copper oxide and sulphuric acid is an experiment involving an insoluble metal oxide which is reacted with a dilute acid to form a soluble salt. Copper (II) oxide, is a black solid, which, when reacted with sulphuric acid creates a cyan-blue coloured chemical called copper II sulfate.
Copper - Wikipedia
Copper is a chemical element with the symbol Cu (from Latin: cuprum) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity.A freshly exposed surface of pure copper has a pinkish-orange color.Copper is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys, such

Copper sulfate | CuSO4 - PubChem
Cupric sulfate is a salt created by treating cupric oxide with sulfuric acid.This forms as large, bright blue crystals containing five molecules of water (CuSO4∙5H2O) and is also known as blue vitriol.The anhydrous salt is created by heating the hydrate to 150 °C (300 °F). Cupric sulfate is used primarily for agricultural purposes, as a pesticide, germicide, feed additive, and soil additive.

Chemical Properties of Metals: Metal Properties, Examples
Dec 21, 2021· As a result, as soon as hydrogen gas is formed in the reaction between a metal and dilute nitric acid, the nitric acid oxidises it to water. Very dilute nitric acid, however, reacts with magnesium and manganese metals to evolve hydrogen gas. This is because the very dilute nitric acid is a weak oxidising agent that cannot oxidise hydrogen to water.
