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.

In estimation of copper and nickel why we are using volumetric for copper and gravimetric for nickel seperately?
It is simply because they could not be found together!! copper can be estimated by treating with potassium iodide and iodine will be liberated in the reaction which is titrated against sodium thiosulphate during the reaction we will add sulphuric acid to prevent the hydrolysis of copper sulphate and we follow by, adding ammonia to neutralize sulphuric as it may hinder the reation between iodide and copper!! now again we will add acetic acid to neutralize ammonia.. and the indicator is added at the last because it will get absorbed with the iodine!! now atlast we add ammonium, thiocyanate to prevent the excess of iodine getting added to copper iodide. end point is disappearance of blue color.
How will excess magnesium be removed from sulphuric acid during experiment'?
you can add more H2SO4 to complete the reaction you can add water and then by filtration
How do you remove excess salt from cooked rice?
put some tomato. that will dilute the curry and balance the salt level by karunaidoss.

How do you separate unused zinc after reacting excess zinc with dilute sulphuric acid?
When excess zinc metal is used in a reaction, it can be removed by simple filtration, as long as the particles are big enough. If the zinc particles are too small to be removed by filtration, other techniques such as centrifugation must be employed.
How do you get rid of excess copper from the body?
I recently had a hair annalysis done and copper was off the charts. How do I get rid of the excess copper?

What is the action of dilute hydrochloride on sodium carbonate?
Dilute hydrochloric acid? Carbon dioxide gas escapes and leaves sodium chloride solution, possibly leaving either an excess of acid, or an excess of sodium carbonate.

Where is the excess copper from after adding zinc to copper sulfate?
The "excess" metallic copper produced by adding zinc metal to a copper sulfate solution comes from exchanging zinc atoms from the metal for copper atoms from the copper sulfate solution. During the reaction, the zinc atoms are ionized to cations and the copper cations from the solution are reduced to neutral atoms.
What is formed when solid copper sulphate is mixed with water?
Take a cupful of water in a beaker and add few drops of dilute sulphuric acid. Heat water. When it starts boiling add copper sulphate powder slowly while stirring continuously. Continue adding copper sulphate powder till no more powder can be dissolved. Filter the solution. Allow it to cool. Do not disturb the solution after some time. We can see the crystals of copper sulphate. If we do not see any crystals, wait for some more time. Your copper sulphate crystal is ready. By: darani.a
How does drinking excess water cause hyponatremia?
Drinking excess water sometimes causes hyponatremia, because the absorption of water into the bloodstream can dilute the sodium in the blood.
Why excess zinc was used in making zinc sulphate crystals?
to ensure that all the sulphuric acid has been used up
How do copper enter the body?
Copper is a metal that is found in food. It is found in foods like pistachios. An excess of copper is called Wilson's Disease and can result in a bluish ring around the colored part of the eye. Excess copper in the body is toxic and can be removed via chelation therapy.
