Simultaneous condensation and absorption of an SO3-water vapour mixture take place when the reactants are brought together above the dew point of the reaction. The resulting gaseous mixture of sulphuric acid, sulphur trioxide and water vapour is led into a plate-type column. Concentrated sulphuric...

Using dilute solutions of TBP (1–5 per cent) in kerosene and in benzene (1 per cent), a maximum in the amount of water extracted from sulphuric acid solution is obtained at about 5 M H 2SO 4. This behaviour can be explained by assuming the following main reaction: TBP(org) + 2H ...
wherek1andk2are the forward and reverse reaction constants. The concentration ofwater vaporis so many orders of magnitude higher than the acid concentration that we can take it to be constant. In equilibrium the time derivative is zero, and we have ...
Re: Why is Quinine sulphate diluted in sulphuric acid for fluorescence analysis? «Reply #3 on:December 05, 2016, 07:40:25 PM » The answer to these sorts of questions can be hard to find, this may boil down to: 1) A reaction with the salt and the sulfate anion. This is almost...

Assertion (A): To dilute sulphuric acid, acid is added to water and not water to acid. Reason (R ): Specific heat of water is quite large. View Solution Assertion (A): To dilute sulphuric acid, acid is added to water and not water to acid ...
ethylsulfonyl group present in compounds selected from the dyestuff class which comprises carrying out the reaction in a machine operating with a kneading action and effect and with the use of only 1 to 5 times the equimolar amount of a concentrated sulfuric acid, of oleum or sulfur dioxide ...
PROCESS OF PRODUCING CONCENTRATED SULPHURIC ACID SO2-containing, hot gases are catalytically converted in part in a first contacting stage. The water and the SO3 formed is removed from the reaction gas. The remaining gas is heated and then supplied to the second contacting stage. The w... KAR...
