How get back copper from nitric acid?
To recover copper from nitric acid, you can add a reducing agent such as iron or zinc to the solution. The copper will be displaced from the nitric acid and form a solid precipitate, which can then be filtered out. This process is known as cementation or displacement reaction.
Which piece of apparatus is used to add dilute nitric acid to potassium hydroxide?
A burette is typically used to add dilute nitric acid to potassium hydroxide in a controlled and precise manner for titration experiments.
How do you separate table salt aluminum filings iron filing?
Use a magnet to remove the iron filings. The add water to dissolve the salt, and the aluminum filings will settle to the bottom of the container. Pour that salt water into a pan, heat it and evaporate the water, leaving the salt in the pan.
How do you dissolve lead oxide?
To dissolve lead oxide, you can use dilute nitric acid. Add the nitric acid to the lead oxide and heat the mixture gently until the lead oxide dissolves. Be sure to handle nitric acid with care as it is a corrosive substance.
Can nitric acid be diluted with water?
Yes, nitric acid can be diluted with water to reduce its concentration and acidity. It is important to add the acid to water slowly while stirring to prevent splashing or releasing heat. Always follow proper safety precautions when handling and diluting nitric acid.
What happen when you add table salt and iron filings?
When you add table salt and iron filings together, they do not react chemically. The salt and iron filings will remain as separate entities in the mixture.

What do you add to sulpuric acid to get iron sulphate?
You would add iron oxide (rust) to sulfuric acid to produce iron sulfate and water in a chemical reaction.
How can you separate a mixture of sand iron filings and salt?
To separate a mixture of sand, iron filings, and salt, you can use a magnet to remove the iron filings, then dissolve the salt in water and filter the sand out. Lastly, evaporate the water to obtain the salt.
How do you raise the pH of nitric acid?
To raise the pH of nitric acid, you can add a base such as sodium hydroxide (NaOH) or potassium hydroxide (KOH) in small increments while monitoring the pH. The reaction will neutralize the acid and increase the pH level. Remember to add the base slowly and carefully to avoid any sudden increase in pH.
How do you prepare 5 percent nitric acid solution from 55 percent nitric acid?
To solve this problem, we basically have 2 equations and 2 unknowns. The unknowns are the (volume of water) & the (volume of 70 wt%) nitric acid to add. * This problem will assume that you are interested in making 1 L (or 1000 mL) of 5 wt% nitric acid solution. Equation 1: (volume of water) + (volume of 70 wt% nitric acid) = 1000 mL Equation 2: mass of nitric acid / [mass of water + mass of 70 wt% nitric acid solution] = 0.05 (0.05 is 5 wt%) * Remember that mass = density * volume * Remember that 70 wt% nitric acid solution mean that for 100 grams (gm) of this acid, then there's 70 grams of HNO3 * Remember that density of 70 wt% nitric acid solution is 1.413 gm/cm^3 * Remember that density of water is 1 gm/cm^3 Equation 2 is now re-written as: [(density of 70 wt% nitric acid soln)*(volume of 70 wt% nitric acid)*0.70] / [(volume water)*(1gm*cm^3) + (volume of 70 wt% nitric acid)*(1.413gm/cm^3)] = 0.05 Solving for the 2 equations gives answer to the 2 unknowns: Answer: To make 1000 mL of 5 wt% nitric acid solution, add 1) 51.63 mL of 70 wt% nitric acid solution 2) 948.37 mL of water
What thing can separate sulfur from iron filings except from magnets?
If the mixture is powdered sulfur and iron filings, use a strong electrostatic field. The sulfur will jump to the opposite charge leaving the conductive iron behind. ***************************** Or, you could add carbon disulfide which would dissolve the sulfur.
