You need to remove the water by evaporation.

I would like to dilute some 5N sulfuric acid with water, and make 0.1N sulfuric acid solution. I want 1000ml of 0.1N . I think it's a 50 to 1 ration, but just want to make sure. <Volume of concentrated> x <Concentration of Concentrated> = <Volume of dilute> x <Concentration of dilute> Therefore, <Volume of concentrated> = <Volume of dilute> x <Concentration of dilute> / <Concentration of dilute> = 1000 mL x 0.1 N / 5N = 20 mL. Meaning: Dilute 20 mL of the 5N H2SO4 to 1000 mL in a volumetetric flask will give you 1000 mLs of 0.1 N H2SO4 (aq.).

no, not really, if you can its very dilute... its probably better to make it. Make concentrated nitric acid ~95% by distilling a mixture of 2 parts nitrate salt and 1 part sulfuric acid.

Use 0.54 mL of Concentrated H2SO4 to 1000 mL DiH2O.

The concentrated sulfuric acid should be diluted to prepare diluted sulfuric acid. The water should not be added directly as the tremendous heat would cause an explosion. Firstly, a desired amount of water should be added to a beaker of similar apparatus. Then it should be followed with the addition of the concentrated acid drop wise.

more dilute not less dilute. "Less Dilute" means more concentrated.

A spoonful of concentrated Sulfuric acid

Add slowly to 1020 mL of water 3.0 mL of conc sulfuric acid. This will give you 0.1 N Sulfuric Acid.

A dilute solution of sulfuric acid (<50%) is a very good conductor. This is because it produces ions in the water that carry the electricity. Concentrated solutions of solutions of sulfuric acid do not conduct electricity well. Sulfuric acid has a hard time making ions with itself (it does not make H3SO4+). Since there is very little water in 99% sulfuric acid, it does not have a lot of ions to conduct electricity. Basically, sulfuric acid does not conduct electricity well because it is molecular, not ionic.

TNT is trinitrotoluene. It can be made by reacting concentrated nitric acid with toluene. It usually needs a small amount of concentrated sulfuric acid to help.

9,8 g concentrated sulphuric acid to 1 L of water (attention to mixing !)

Since vinegar is dilute, first we have to boil it to make it concentrated. When acid is about 97% , keep it with phosphoric anhydride. As a powerful desiccant it will dehydrate Concentrated acetic acid into Acetic anhydride.

first make 10N solution by addind 27.7ml conc H2So4 in 73.3ml water then take 1 ml from 10N and add 999ml water

Ammonia, NH3, should be used to react with (dilute) sulfuric acid.

A dilute acid is one that is not very concentrated. You can make an acid solution more dilute by adding water. Note that you have to be careful with the terms strong and weak; very strong acids can also be very dilute. Strong and weak characterize the acid's ability to dissociate in an aqueous solution, independent of concentration.

Sulfuric acid is as pure or as contaminated as you make it.

its very simple! to make a concentrated solution dilute, all you have to do is add a little water to it!

No, it is not possible to convert sulfuric acid to nitrous acid.

It is impossible; and don't drink sulfuric acid.

Only when the sodium chloride is in solid form ad sulphuric acid is concentrated. The results are hydrogen chloride gas and sodium hydrogen sulphate. By dissolving hydrogen chloride in water, you make hydrochloric acid.

Nothing significant happens. You only make the acid dilute or you reduce the concentration of that acid. As a result, it becomes less dangerous. Even sulphuric acid had once fallen on my fingers, but luckily it was dilute. Heat will be generated, the amount dependent on the quantity and concentration of the acid. This amount of heat may be significant....

The element that can be found in nature and is used to make sulfuric acid is Sulfur.

Most succesfully you should try with dilute nitric acid, be careful with concentrated acids. All nitrates are soluble!

How do you make phosphoric. Acid into hypophosphite

sulfuric acid and nitric acid
