What happens when copper reacts with concentrated nitric acid? Give balanced chemical equation. View Solution (a) How does benzene diazonium chloride react with (i) phenol (ii) aniline (b) Describe the method for the identification of primary, secondary and tertiary amines. Also write chemical ...
Why does copper not react with water or steam? Why is chloroacetic acid stronger than acetic acid? Why is sodium bicarbonate used in fire extinguishers? Why is burning a chemical reaction? Why does sodium carbonate not decompose when heated?
Since limestone is mostly calcium carbonate,it is damaged by acid rain. Sodium carbonate, magnesium carbonate, zinc carbonate and copper carbonate also react with acids - they fizz when in contact with acids, and the carbon dioxide released can be detected using limewater . Calcite and Dolomite ...
Nitric acidFeather analysis has been widely used as a biomonitoring tool to assess metal contamination in birds, as their sampling is a non-destructive and ethically preferable technique. However, for feathers to be useful as a biomonitor of heavy metals, exogenous contamination has to be ...
Why is copper (II) sulfate solution a good conductor of electricity? Why are galvanic cells kept in two different half-cells? Explain why aluminum does not react with potassium nitrate (KNO3) although it reacts with copper nitrate (Cu(NO3)2). ...

The sulfuric acid, in addition to removing the alcohol from the air, also might provide the acidic condition needed for this reaction. During this reaction, the reddish-orange dichromate ion changes color to the green chromium ion when it reacts with the alcohol; the degree of the color ...
This formed when the copper sulphate in the indicator was reduced by/reacted with the (reducing) sugars in the test solution. Why do we need to heat the solutions?We need heat to provide the energy for the reaction. The human body needs glucose as a fuel for all the cells. ...
As shown in Fig.1, DA extracted from disproportionated rosin could be chemically modified to its derivative DAMBA41, which is herein applied as a precursor to react with a series of various substituted salicylaldehyde to yield their corresponding Schiff bases, DAMB-SA, DAMB-SAB, and DAMB-SAN,...
A sample of tap water produces a white precipitate when treated with silver nitrate. What ion is most responsible for this effect? What is the white precipitate? There are two reactants, copper (II) oxide and hydrochloric acid. The products are copper (II) chloride an...
