Dissolve it in diluted nitric acid. WARNING: This is potentially highly dangerous and proper safeguards should be employed, for example gloves, facemask, fume cupboard with shield down etc etc. and take advice.

These react with acids to make salt and water?
Insoluble metal oxide + strong acid ---> salt + water
What does metal oxide and nonmetal oxide make?
Metal oxide reacting with a nonmetal oxide makes a salt.Examples:CaO + CO2 --> CaCO3PbO + SO3 --> PbSO42 NaO + H2O --> 2 NaOH
Why do you heat an copper oxide and sulfuric acid?
Most metal oxides react with dilute acids.The reaction between an insoluble metal oxide and a dilute acid is often quite slow so it is possible to observe the progress of the reaction as the solid reactant disappears as a soluble product is formed. Hence to enhance the speed of the reaction, excess Copper Oxide is used in preparing Sulphate Salt.
How do you know if something is soluble or insoluble?
Two important rules are: - polar compounds are soluble in water - nonpolar compounds are soluble in nonpolar solvents But is essential to make experiments to determine the solubility.
What happens when silver reacts with air?
it tarnishes and can make a dull layer of metal oxide on the surface"tarnish" or oxidation.
These react with acids to make salt and water?
Insoluble metal oxide + strong acid ---> salt + water
Insoluble base used to make copper sulfate?
copper (II) oxide
What insoluble base used to make copper sulphate?
copper (II) oxide
Is it best to get both kind of fiber in your diet insoluble and soluble?
soluble fiber is digestable, and insoluble fiber is not.1 will dissolve to make a solution, 1 won't.
What does metal oxide and nonmetal oxide make?
Metal oxide reacting with a nonmetal oxide makes a salt.Examples:CaO + CO2 --> CaCO3PbO + SO3 --> PbSO42 NaO + H2O --> 2 NaOH
Is white sand soluble in water?
Beach sand, or white sand, has the molecular formula, SiO2 and is used to make glass. It is completely insoluble in water
How do you make a metal oxide into a metal?
The final stage of metal refining is typically electrolysis.
Which metal oxide is often added to paint to make it bright white?
Antimony oxide
How could you make a substance that is insoluble in water-soluble?
Insoluble generally means that a substance does not dissolve in water. Some examples include: sand, fats, wood, metals, and plastic. So you'd just make an item out of one of those insoluble parts.
How would you make a soluble salt from an from an insoluble base?
Most succesfully you should try with dilute nitric acid, be careful with concentrated acids. All nitrates are soluble!
What is the reaction of metallic oxide with water?
Reaction of a metal oxide with water produces a metal hydroxide, which is a strong base
