sulphuric acid can not be neutralised by water but can be diluted with water. add drops of acid to water carefully with constant stirring as the reaction is exothermic. to neutralise sulphuric acid, strong bases like naoh can be used. 5. is sulfuric acid ionic or molecular? water forms a...

Stabilization of H2SO4–H2O Clusters by Organic AcidsWhile atmospheric aerosols are known to contain a significant fraction of organic substances, the influence of organics on the formation of H2SO4–H2O clusters and subsequent nucleation in the......
reaction of SO_2 with OH radicals.OH radicals were formed from alkene ozonolysis or photolytically.Furthermore,the possible contribution of organic ozonolysis products to particle growth was investigated.In contrast to earlier studies,the ozonolysis was conducted for reactant concentrations closer to ...
Uranyl ions compete with XeF 2 molecules for sorption on these centers, thus inhibiting the reaction.doi:10.1023/B:RACH.0000039114.35719.4cS. V. LotnikInstitute of Organic Chemistry, Ufa Research Center, Russian Academy of Sciences, Ufa, Bashkortostan, RussiaL. A. Khamidullina...
Organic chemistry, Physical chemistry, Catalysis, ab initio calculations, Reaction mechanism, SuperacidThe mechanism of the (CH3)2CCH2+H2O→(CH3)3COH reaction catalyzed by two strong acids (H2SO4 and HSbF6) was investigated theoretically using the ab initio MP2 and CCSD(T) methods and the ...
In the second one, leaching was carried out by using glucose in the H2O/H2SO4 reaction media and after leaching, the aqueous solution was separated from the solid by filtration. Successively, alcohols were added to the leach liquor. The experimental results of Mn, Ca, and Fe dissolution ...
