How do you make 1N sulphuric acid?
To make 1N sulfuric acid, dilute concentrated sulfuric acid (around 18M) with water in a 1:18 ratio. For example, mix 1mL of concentrated sulfuric acid with 18mL of water to obtain approximately 1N sulfuric acid solution. Always add acid to water slowly while stirring to avoid splattering and heat generation. Safety precautions should be followed when working with concentrated acids.
Safest way to dilute concentrated sulfuric acid?
To dilute concentrated sulfuric acid, always add the acid to water slowly while stirring constantly. Never pour water into concentrated acid, as this can cause a violent exothermic reaction. It is important to wear appropriate personal protective equipment and work in a well-ventilated area when handling sulfuric acid.
What is 1.3 specific gravity sulfuric acid?
A 1.3 specific gravity sulfuric acid solution means that it is 1.3 times denser than water. This solution would contain approximately 49.1% sulfuric acid by weight. It is a relatively concentrated solution and should be handled with care due to its corrosive nature.
How do you prepare 1M sulfuric acid from concentrated sulfuric acid?
To prepare 1M sulphuric acid from concentrated sulphuric acid:First consider the molecular weight of H2SO4 = 98 g/mol, so you have to add 98g of conc. acid and make up to 1 liter of water (as pointed out at the 4thpoint).Considering that acid is a liquid, you should also consider density: where density = mass/volume, which is said on the bottle to be (about) 1.84 g/mL,so then you have: volume = 98g / 1.84(g/mL) = 53.2 mLNow you have to consider the acid purity, usually 98% then you have to do this: 53.2 mL if the acid were 100% pure convert in mL given with the purity of 98%, so 100% x 53.2 mL / 98% = 54.3 mL of (98%) concentrated acid.Finally CAREFULLY add this 54.3 mL (or 98 g, cf. first point) to about 0.9 L dist. water while continuously stirring (evolving heat!), and after that fill it up to 1.00 L with also dist. water. Never reverse this: DO NOT add water to concentrated fluids!
Is concentrate sulfuric acid corrosive?
Yes, concentrated sulfuric acid is highly corrosive. It can cause severe burns on contact with skin and irreversible damage to eyes. It should be handled with extreme caution and proper protective equipment.
Why should water never drop-wise to concentrated sulfuric acid?
Water should never be added drop-wise to concentrated sulfuric acid because the reaction is highly exothermic, meaning it releases a large amount of heat. Adding water drop-wise can cause the acid to rapidly heat up, potentially boiling and splattering the acid. This can lead to dangerous acid burns, fumes, and possible explosions.
What happens when lead acetate is added to concentrated sulfuric acid?
Pb2+ --> PbSO4(s)Concentrated sulfuric acid will 'burn' or 'carbon'ise acetate (CH3COO-) to Carbon black, CO2(g) and H2O(l) and some other intermediate products.Be very carefull! Very exothermic!You should never work with concentrated acids un-gided and unprotected!.
When concentrated h2so4 splits on the surface how it should be immediately cleaned?
If concentrated sulfuric acid spills on a surface, it should be immediately cleaned by first neutralizing it with a base such as sodium bicarbonate or calcium carbonate. This will help to neutralize the acid and reduce its corrosive properties. Afterwards, the area should be rinsed thoroughly with water and appropriate protective equipment should be worn during the cleaning process.
How do you prepare liebermann burchard reagent?
To prepare the Liebermann-Burchard reagent you add 200 ml of cold acetic anhydride and 200 ml of glacial acetic acid at room temperature to a 500 ml amber glass bottle that has a polyseal cap. Turn the bottle upside down to mix the solution then add 30 ml of cold concentrated sulfuric acid.
Is cocentrated sulphuric acid flamable?
No it is not. However if handling it you should be very careful as it can disolve its way through most anything very quickly (ie: your glove, your hand, the table you're sitting at, your crotch, etc)
Reaction of potassium astatide with concentrated sulfuric acid?
KAt + H2SO4(conc) = KHSO4 + HAt displacement then .......HAt + .......H2SO4 = At2 + H2S which can be balanced as follows: 2At- = At2 + 2e ] * 4 8e + 8H+ + H2SO4 = H2S + 4H2O overall is 8At- + 8H+ + H2SO4 = H2S + 4H2O + 4At2
Another student forgets to add concentrated sulfuric acid to the reaction mixture in attempt to synthesise aspirin what would you expect the ferric chloride test to show Why?
you should expect a purple color because the reaction would not go through with out the catalyst sulfuric acid. If the reaction did go through you would expect a yellow color with pure aspirin
