3.Applications:

Water effluent treatment system
It's used for purification of drinking water and wastewater treatment by settling of impurities by

means of precipitation and flocculation.

Paper Industry
It helps in sizing of paper at neutral and alkaline pH, thus improving paper quality (reducing spots

and holes and improving sheet formation and strength) and sizing efficiency.

Textile Industry
It is used for color fixing in Naphthol based dyes for cotton fabric.

Other Uses
Leather tanning, lubricating compositions, fire retardants; decolorizing agent in petroleum, deodorizer; food additive; firming agent; dyeing mordant; foaming agent in firefighting foams; fireproofing cloth; catalyst; pH control; waterproofing concrete; aluminum compounds, zeolites etc.

Q:Why can some catalysts be reused in (chemistry)?
Because the catalyst in the chemical reaction before and after the quality and chemical properties have not changed, so in the chemical reaction can be reused.
Q:How does the catalyst for organic synthesis look for?
This problem is difficult to answer comprehensively because the study of the different directions of the catalyst is different.
Q:What is the nature of the catalyst before and after the chemical reaction?
Chemical properties do not change better. Some properties of the catalyst may change before and after the reaction. If the experiment proves, the state of the catalyst before and after the reaction changes, and some changes from powder to powder.
Q:Why does the chemical and chemical properties change before and after the reaction?
Catalysts are homogeneous catalysts with heterogeneous catalysts. The heterogeneous catalyst exhibits a reaction in a different phase (e.g., a solid catalyst in a liquid mixing reaction) and a homogeneous catalyst is a reaction in the same phase (for example, a liquid catalyst in a liquid mixing reaction). A simple heterogeneous catalytic reaction involves the addition of a reactant (or en-ch: substrate; zh-tw: subject) adsorbed on the surface of the catalyst, and the bond within the reactant causes a new bond due to the fragility of the bond, But because of the product and the catalyst between
Q:What is positive and negative catalyst in chemistry?
Negative catalysts are, on the other hand, slowing down the positive reaction rate at the same time
Q:why is palladium/platinum a good catalyst?
Palladium and platinum are good catalysts because they _adsorb_ certain molecules, especially gases. Adsorption is NOT the same as _absorption_. Adsorption is a process by which a chemical (gases or liquid) physically becomes attached to the _surface_ of an adsorbate (a solid). Once gas molecules are adsorbed on the surface of a catalyst, they are much nearer each other and more likely to react. Absorption is a process by which a gas or liquid is incorporated throughout the volume of an absorbate (a solid), rather than just on the surface. The fact the palladium happens to _absorb_ hydrogen molecules well probably has little to do with its function as a catalyst and is probably just a coincidence. In fact, two of the main reactions in a catalytic converter don't involve molecules with hydrogen atoms at all. On the other hand, WHY platinum and palladium are good catalysts are a mystery. Presumably, they are good at enhancing the Van der Waals forces that cause adsorption with other molecules, but WHY the platinum family of metals do this better than other metals is not fully understood (I don't think).
Q:What are the characteristics of the catalyst in the catalytic reaction?
The role of the catalyst in the chemical reaction is to change the rate of chemical reaction, and its own quality and chemical properties do not change.
Q:Why are transition metals more likely to be catalysts?
transition okorder.com/... for ex-- X (one reactant) + catalyst(transition element) ------X.catalyst(intermediate unstable compound) X.catalyst + Y (other reactant) --------XY(product) + catalyst how the change in oxidation state of transition elements helps the reacton through the formation of intermediates may be seen from reaction in between SO2 and O2 to form SO3 in presence of V2O5 ... V2O5 + SO2 ------V2O4 + SO3 2V2O4 + O2 ------2V2O5 in the above reaction vanadium changes its oxidation state from +5 to +4 and again to +5.. another example is reaction in between iodide and persulphate ions in presence of Fe(III) as catalyst... 2I(-) + S2O8(2-) ---------I2 + 2SO4(2-) (Fe(III) is present as catalyst) the reaction is believed to take place as follows: 2Fe(3+) + 2I(-) ------2Fe(2+) + I2 2Fe(2+) + S2O8(2-) ------2Fe(3+) + 2SO4(2-) (3)in number of cases transition elements provide a suitable large surface area with free valencies on which reactants are absorbed ...as a result concentration of reactants on surface of catalysts increases..hence rate of reaction increases...this is known as adsorption theory.... according to adsorption theory : there are free valencies on surface of solid transition metals because of the incomplete d-subshelll.. so the mechanism of catalysis involve followin five steps: (1) diffusion of reactant molecules towards surface of catalyst... (2) adsorption of reactant molecules on surface of catalyst by forming loose bonds with catalyst due to free valencies... (3)occurence of chemical reactions between reactant and catalyst forming an intermediate.. (4)desorption of product molecules from surface due to its lack of affinity for the catalyst surface thereby making the surface free for fresh adsorption of reactant molecules... (5)diffusion of product molecules away from surface of catalyst...
Q:Does the catalyst participate in chemical reactions?
The catalyst does not participate in the chemical reaction, it only plays an auxiliary role.
Q:reactants are constant or the quality and chemical properties of the catalyst are constant?
The change in chemical reaction rate is the same as the chemical nature and quality
