Does copper react with dilute nitric acid?
Yes, copper reacts with dilute nitric acid to form copper(II) nitrate, nitrogen dioxide gas, and water. The reaction between copper and dilute nitric acid is a redox reaction where copper is oxidized from its elemental form to copper(II) ions, and nitric acid is reduced to nitrogen dioxide gas.
Why is nitric acid in the dilute form not used in the laboratory preparation of hydrogen from metals?
It is because nitric acid is a strong oxidising agent (because it decomposes to yield nascent oxygen as:2HNO3 →2NO2 + H2O + [O])and it oxidises the hydrogen formed to water.Only 1% dilute and cold nitric acid reacts with magnesium and manganese to liberate Hydrogen gas.
What is the balanced equation for the reaction of phosphorus with concentrated nitric acid?
Pieces of copper are added to hot concentrated solutions of hydrochloric, phosphoric, sulfuric and nitric acids. A reaction clearly takes place between copper and nitric acid. The presence of copper ions can be observed by adding each solution to a dilute solution of ammonia. If copper ions were present, we would see the blue color of the copper-ammonia complex. Sulfuric acid has oxidized the copper metal, as indicated by the blue color. Nitric acid is a stronger oxidizing agent (and produces a higher concentration of copper(II) ions), as indicated by the darker blue color.
What would be expected when sodium hydroxide solution is added gradually to a conical flask of dilute nitric acid containing universal indicator?
The sodium hydroxide will neutralize the nitric acid, resulting in a color change of the universal indicator from red to purple to blue, indicating the solution is becoming more basic. This reaction will also generate heat due to the exothermic nature of the neutralization reaction.
What happens when nitric acid is mixed with methyl orange?
When nitric acid reacts with methyl orange, the color of the solution changes. Methyl orange is an indicator that changes color from orange/yellow in acidic solutions to red in basic solutions. In the presence of nitric acid, which is a strong acid, the solution would turn red.

Can you breed a buckskin stalllion and a paint mare and get a buckskin paint?
Well possibly, this would mainly depend on the color of the mare. Buckskin is a dilute color and will dilute the base color of a horse (Bay + Cream= buckskin etc,).

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!

Carbon dioxide and bromothymol blue?
Carbon dioxide can react with water to form carbonic acid, which can lower the pH of a solution. Bromothymol blue is a pH indicator that changes color from blue to yellow in acidic solutions. When carbon dioxide is bubbled through water containing bromothymol blue, the solution will turn yellow due to the decrease in pH caused by the formation of carbonic acid.
What are the products when HCL reacts with Na2CO3 using bromothymol blue as indicator?
the products of this reaction is NaCl, H2O and CO2. this is because the bromothymol has a pka of 7.1 and it changes color from yellow to blue in acidic medium just like metyl orange. the products of this reaction is NaCl, H2O and CO2. this is because the bromothymol has a pka of 7.1 and it changes color from yellow to blue in acidic medium just like metyl orange.
What will hppen if you put a piece of magnesium into dilute nitric acid?
Im not sure about very dilute acid and strong magnesium but; magnesium and dilute nitric acid formed alot of gas, the color changed to a browney orange and the temperature increased significantly. I was told (by my science teacher) that when writing the chemical equation you didnt have to include water so; magnesium + nitric acid-------> magnesium nitrate + hydrogen Hope this helps. :)
What acid and base would you use to make zinc nitrate?
To make zinc nitrate, you would typically react nitric acid with zinc oxide or zinc metal. Nitric acid is the acid needed for the reaction, while zinc oxide or zinc metal can serve as the base to neutralize the acid and form zinc nitrate.
What colour is made by mixing bromothymol blue and sulphuric acid?
Mixing bromothymol blue and sulfuric acid would not result in a colour change, as sulfuric acid is a strong acid and bromothymol blue is a pH indicator that changes colour based on the acidity or alkalinity of a solution.
