Mention two examples of emulsifying agents for o/w emulsions and w/o emulsions.

Some substances such as alkaline potassium permanganate and acidified potassium dichromate are capable of adding oxygen to others. These are known as oxidising agents.

Proteins used as therapeutic agents are as follows:  Thrombin and fibrinogen – They help in blood clotting.  Antigen (antibody) – It helps in blood transfusion.  Insulin – It helps in...

In sulphur dioxide (SO2), the oxidation number (O.N.) of S is +4 and the range of the O.N. that S can have is from +6 to –2.  Therefore, SO2 can act...

Oxidizing agent = MnO4 – and Reducing agent = Fe2+  Oxidizing agent = Cr2O7 2– and Reducing agent = Fe2+ . 

(a) Electrochemical series: Arrangement of metals (non-metals also) in increasing order of their reducing power or vice versa.  (b) Redox reaction: Reactions in which both Oxidation and reduction take place simultaneously...

Oxidizing agents = H2SO4 and Reducing agents = Fe  Oxidizing agents = Cl2 and Reducing agents = H2  Oxidizing agents = MnO2 and Reducing agents = HCl.

[Hint : Those agents which stabilize emulsions. It acts as binding agent between two immiscible liquid phases.]

[Hint :   (a) By dilution test                (b) By dye test]

[Hint : Heterogeneous catalyst, activity and selectivity of catalysts. Example, Hydrogenation of unsaturated hydrocarbons in presence of Raney Ni or any other example.]

Artificial sweetening agents: These are the substances which are non-nutritive in nature and used as substitutes for sugar in foods and beverages. Examples: Aspartame: Aspartame is 100 times as sweet as cane...
