What is conc sulfuric acid?

Conc sulfuric acid is short for concentrated sulfuric acid, which refers to sulfuric acid that has a high concentration of H2SO4, typically around 95-98%. This form of sulfuric acid is highly corrosive and can cause severe burns upon contact with skin. It is commonly used in industrial processes such as manufacturing chemicals, refining petroleum, and in laboratory settings.


What happen when H3PO4 is used instead of H2SO4 in preparation of dry NH3?

If H3PO4 is used instead of H2SO4 in the preparation of dry NH3, the most common method being the reaction with an ammonium salt like NH4Cl or NH4NO3, the reaction will still occur but phosphoric acid (H3PO4) may impart some impurities or affect the yield compared to sulfuric acid (H2SO4). However, the overall process will still generate dry ammonia gas. The choice between H3PO4 and H2SO4 depends on the specific requirements of the experiment or application.


What are the properties and uses of conc. H2SO4?

Concentrated sulfuric acid (H2SO4) is a strong mineral acid that is highly corrosive and can cause severe burns. It is commonly used in various industries for purposes such as manufacturing fertilizers, refining petroleum, and in the production of chemicals. Its properties include being a strong dehydrating agent, a powerful oxidizing agent, and a catalyst in various chemical reactions.


Why HCl and HNO3 can be used in combination but HCl and H2SO4 not?

this is because when hcl and hno3 is mixed then it ionizes into h+and cl- and and and you may knaw rust is the mixing of foriegn particles in the pure substances. eg-fe+o2=fe2o3 so when gold is mixed with hcl and hnoc the it gives off aucl4. ie au pure gold is mixed with the pollutant cl4 similarly when h2so4 cant be used because s04 is not the neutral radical like no3 of hno3 thus s04 not being neutral and no3 being neutral h2so4 cant be used


How do you standardize 1N H2SO4 with a KHP?

To standardize 1N H2SO4 with KHP, you would first prepare a solution of KHP of known concentration. Then, titrate the KHP solution with the 1N H2SO4 solution until the endpoint is reached. The volume of H2SO4 used in the titration can then be used to calculate the exact concentration of the H2SO4 solution.


Is h2so4 a acid or base?

H2SO4 is a strong acid known as sulfuric acid


Sodium formate is heated with conc sulphuric acid?

When sodium formate is heated with concentrated sulfuric acid, it undergoes dehydration to form sodium oxalate and water. This reaction typically occurs at elevated temperatures and can be used as a method for preparing sodium oxalate.


H2SO4 what is this base or acid?

H2SO4 is sulfuric acid, which is a strong mineral acid. It is widely used in various industrial processes and laboratory experiments.


A 25.00ml sample of h2so4 requires 22.65 ml of the 0.550m naoh for its titration what was the concentration of sulfuric acid?

The balanced chemical equation for the reaction is H2SO4 + 2NaOH -> Na2SO4 + 2H2O. From the mole ratio, 1 mole of H2SO4 reacts with 2 moles of NaOH. Using the volume and concentration of NaOH, we can calculate the moles of NaOH used. Then, knowing the moles of NaOH used and the volume of H2SO4, we can find the concentration of sulfuric acid.


Is H2SO4 oxidising?

H2SO4 is sulphuric acid To find out more about his material go to the related link(H2SO4) below


How do you calculate the moles of H2SO4 in a titration?

To calculate the moles of H2SO4 in a titration, you can use the formula: moles Molarity x Volume. First, determine the molarity of the H2SO4 solution. Then, measure the volume of the solution used in the titration. Multiply the molarity by the volume to find the moles of H2SO4.


What is the procedure to prepare anthrone reagent?

To prepare anthrone reagent, dissolve 200 mg of anthrone in 100 ml of concentrated sulfuric acid. Mix the solution thoroughly and allow it to cool before use. Anthrone reagent is used for the detection of carbohydrates, specifically sugars, in various biological samples.
