Adding acid is "belt and braces" - iron II is readily oxidised to iron III but this is greatly reduced in the prescence of the ammonium ion which is slightly acidic. Adding more acid merely futher reduces the tendancy for oxidation of the iron II.

What happens when you add universal indicator to sulfuric acid?

It turns the universal indicator to scale 1


If zinc is first added to dilute sulfuric acid then concentrated sulfuric acid and acetic acid in which case will the fizzing be most and least?

The most fizzing will come from the concentrated sulfuric acid, then dilute sulfuric acid, then the acetic acid.The amount of fizzing is due to the concentration of H+ in the solution, and concentrated sulfuric acid has the most H+ in solution. The dilute sulfuric acid has less (because it is dilute) and the acetic acid solution has the least of all because it is a weak acid rather than a strong acid.See the Related Questions for more information.


When lithium hydroxide pellets are added to a solution of sulfuric acid what is formed?

When lithium hydroxide pellets are added to a solution of sulfuric acid Lithium Sulfate and water are formed. The balanced equation is 2LiOH + H2SO4 ------> Li2SO4 + 2H2O


An aqueous solution of sodium sulphate containing sulfuric acid is?

Aqueous solutions of sodium sulfate do not contain sulfuric acid as they are separate compounds. If sulfuric acid is added to the solution, a reaction may occur to form sulfuric acid and sodium sulfate may dissociate into its ions in water.


What colour does sulfuric acid turn when you put methyl orange in?

Sulfuric acid will turn red when methyl orange is added, indicating that the solution is highly acidic.


Why sulfuric acid added to water during electrolysis?

Sulfuric acid is added to water during electrolysis to increase the conductivity of the solution. This helps ions move freely in the solution and facilitates the electrolysis process by allowing the flow of electric current. It also helps in stabilizing the pH of the solution.


What is the name of the aqueous solution of H2SO4?

The aqueous solution of H2SO4 is called sulfuric acid.


Why sulphuric acid is added in silver nitrate solution in electroplating?

Sulfuric acid is added to the silver nitrate solution in electroplating to increase the conductivity of the solution. This allows for better passage of electric current through the solution, aiding in the deposition of silver onto the object being plated. Additionally, sulfuric acid helps in maintaining the pH of the solution at an optimal level for the electroplating process.


Why is sulfuric acid added to sodium ethanedioate and hydrated ethanedioic acid?

to acidify the solution so that it can become a good oxidising agent


What colour should sulfuric acid be after universal indicator is added?

Sulphuric Acid is colourless. When universal indicator (UI) is added, sulphuric acid remains colourless. The universal indicator turns 'RED'. Howver, because the UI is in solution with the sulphuric acid, the solution appears to be red.


What volume in mLs of 0.100 M sodium hydroxide solution must be added to 20.0 mL of 0.08 M sulfuric acid solution to reach the end point?

To neutralize the sulfuric acid completely, you need a 1:2 molar ratio of sodium hydroxide to sulfuric acid. Therefore, you would need to add twice the amount of sodium hydroxide compared to the amount of sulfuric acid, which is 40.0 mL of the sodium hydroxide solution.


What percentage of sulfuric acid is 40 grams per liter?

A 40 grams per liter solution of sulfuric acid would be approximately a 4% solution. This is calculated by dividing the mass of sulfuric acid by the total mass of the solution and multiplying by 100.
