What is the name of the ionic compound Cu(NO3)2?
This compound is copper(II) nitrate.
Is copper sulfate a compound or an element?
Copper sulfate (CuSO4) is a compound as it contains the elements copper, sulfur and oxygen chemically combined. Copper, sulfur and oxygen are elements because they cannot be broken down into any simpler forms of substance. Anhydrous copper sulfate appears as a white solid while hydrated copper sulfate appears as a blue solid.
What do the roman numerals mean in Copper II?
The Roman numeral II in Copper II denotes the oxidation state of copper, which is +2. This indicates that copper in the compound has lost two electrons and has a 2+ charge.
What are the colours of cuso4.6h2o?
The compound CuSO4·6H2O, known as copper(II) sulfate pentahydrate, appears as blue crystals.
Why does a black colour come when you put a copper coin on yop of a Bunsen flqme?
When a copper coin is heated on a Bunsen flame, it undergoes oxidation, forming copper oxide. Copper oxide is a black compound, which is why the coin appears black.

What is the ratio of copper II ions to phosphate ions?
The ratio of copper(II) ions (Cu2+) to phosphate ions (PO4 3-) in the compound copper(II) phosphate (Cu3(PO4)2) is 3:2. This is because the formula of copper(II) phosphate indicates that there are three copper(II) ions for every two phosphate ions in the compound.
When copper chloride reacts with aluminum why does the color of the solution seem to fade?
When copper chloride reacts with aluminum, the aluminum replaces the copper in the compound through a single displacement reaction. The resulting compound formed, aluminum chloride, is colorless in solution. Therefore, the color of the solution appears to fade as the copper is displaced and the products of the reaction are colorless.
Is copper sulphate a compound?
Yes, it is a compound of copper, and sulfur( sulphur) Hence, Copper sulphate
Is copper oxide an element or a compound?
Copper is a chemical element. It can be a compound but copper is usually known as a chemical element.
