Spills of some mL's can be cleaned up by absorption of very wet filter paper (at least with 20 fold excess of water). Than add hydrated sodium carbonate (soda) untill no more carbon dioxide escapes. Put all in plastic container bag.

What happen when KBr is heated with conc H2So4 acid?
Balanced equation formed: H2SO4 + 2KBr ==> 2HBr + K2SO4
How will you prepare picric acid from benzene?
React benzene with conc. H2SO4 and then with conc. HNO3. The resultant would be picric acid
What is the procedure to prepare anthrone reagent?
0.2% of anthrone was dissolved in 100ml of conc H2SO4.
How do you prepare ethereal hcl?
You drop conc. HCl into conc. H2SO4 - this releases HCl gas which you can bubble through dry ether... Or, you use an HCl cylinder.
What is conc sulfuric acid?
Concentrated sulphuric acid. It is H2SO4 in a concentration of probably 6M or above.
Why it is necessary to add conc H2SO4 in conc HNO3 but not vice versa?

What ch3ch2oh gives CH3CHO?
conc. H2so4
Why the conc h2so4 cant be used in preparation oh h2s?
h2so4 being good oxidising agent oxidises the h2s to h2o and free sulphur.so conc h2so4 cant be used in preparation of h2s gas

What is the reaction between Sulfuric acid and hematite?
3h2so4+fe203------>fe2(H2So4)3 + H20 conc.
What do you use nitric acids for in laboratory?
lABORATORY METHOD:Nitric acid can be prepared in he laboratory by the action of the conc. h2so4 on the potassium nitrate
Sodium formate is heated with conc sulphuric acid?
2 HCOONa + H2SO4 → 2 CO + 2 H2O + Na2SO4
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
