The formula of fuming sulfuric acid is: a) H2SO4.SO3 b) H2SO4.SO2 c) H2SO4.HSO2 d) H2SO4.HSO3 e) H2SO4.SO Why does it take more NaOH to neutralize H2SO4 than in HCl? 1. Why H2SO4 is strong acid than H2SO3? 2. Why HClO2 is strong acid than HClO? 3. Why HClO is...
A strong acid is the one which is 100% ionised solution. Sulphuric acid and nitric acid are the strong acid . Strong acid have pH 0-1. pH is the measure of concentration of hydrogen ions of solution. Lower the pH , higher the concentration of hydrogen ions in the solution....
The formation mechanism of aerosol sulfate during wintertime haze events in China is still largely unknown. As companions, SO2 and transition metals are mainly emitted from coal combustion. Here, we argue that the transition metal-catalyzed oxidation of
Membranes comprising an aromatic ether ketone polymer (e.g. polyetherketone) in sheet or hollow fibre form are made by preparing at least a 12 wt % solution of the polymer in a solvent which is chemically inert to the polymer (e.g. concentrated sulphuric acid); forming a film of the sol...
They determined that the SO2F2- mediated acid activation forms a transient anhydride intermediate that transforms into the analogous acyl fluoride. They also report that tetrabutylammonium chloride or bromide accelerate the formation of acyl fluoride. ReactIR measurements provided insight into the mechanism...
**Particulate matter (PM10) is a major component of air pollution that threatens both our health and our environment. It consists of very small liquid and solid particles floating in the air. **Sulfur dioxide(SO2) acts as an acid.Inhalation(吸入) results in labored breathing, coughing, or ...
It is suitable to oxidize SO2 in flue gas on thermodynamic using a strong ROS produced from electro-Fenton reaction [311]. Meanwhile, sulfuric acid can be sold as a chemical to obtain economic benefits. H2 is generated on cathode during the electrolysis process and can be further recovered. ...

R4 is a single cyano group in the para-position relative to B. The process of the -invention may be carried out, for example in the presence of a suitable dehydrating agent (such as: a strong acid (e.g. sulfuric acid (e.g. concentrated sulfuric acid), methanesulfonic acid (e.g. anh...
What ions and / or molecules are present in relatively large proportions in a solution of a strong acid HI (aq)? Which of the following acids will have the highest K_a value? a) NaH b) H_2S c) H_2S Which of the fo...
