coagultion is the process by which the dispersed phase of a colloid is made to aggregate and thereby separtate from the continuous phase. The minimum concetration of an eletrolyte in milli-moles per litre of the electrolyte solution which required to cause the caogultion of colloidal sol is called coagution value . therefroe higher is the coagulatings power of effective ion, smaller will be the coagultion value of the electrolyte. the ability of an ion to bring about coagulation of a given colloid depends upon :

Which of the following electrolyte requires maximum concentration to cause coagulation of As_2S_3 sol ?

In coagulation of a (colloidal) solution of As_2S_3 , which has maximum coagulating power ?

Under the influemce of an electric field, the particles in a sol migrate towards cathode. The coagulation of the same sol is studied using NaCl,Na_(2)SO_(4) , and Na_(3)PO_(4) solutions. Their coagulation values will in the order a. NaClgtNa_(2)SO_(4)gtNa_(3)PO_(4) b. Na_(2)SO_(4)gtNa_(3)PO_(4)gtNaCl c. Na_(3)PO_(4)gtNa_(2)SO_(4)gtNaCl d. Na_(2)SO_(4)gtNaClgtNa_(3)PO_(4)

Arrange the following electrolytes in the increasing order of coagulation power for the coagulation of As_(2)S_(3) sol : K_(2)SO_(4) " " CaCl_(2)" " Na_(3)PO_(4) " " AlCl_(3) : Ilt II lt IIIlt IV , I=III lt II lt IV , II lt IV lt I lt II , II lt III lt IV lt I .

what is the correct sequence of the decreasing coagultion value of the following electrolyte for the coagultion of ferric hydroxide sol ? (I) Na_(3) PO_(4) (II)KCl (III) K_(2)SO_(4) (IV)K_(4)[Fe(CN)_(6)]

A colloidal solution is a type of mixture which consists of particles whose size varies between 1 and 1000 nanometres. In colloidal solution the particles are distributed evenly. During this process the particles do not settle down. This is one of the best know thing about colloidal solutions. Properties of colloids and their variation are a well-known area ever since the primitive age. The best example to prove their familiarity with us is that we know from very early times that coagulation of milk results in the formation of curd. Physical properties of colloids 1. The nature of the colloidal solution is heterogeneous i.e. unlike. These solutions dwell with two different phases : • Dispersed medium Dispersed phase. 2. Despite the fact that colloidal dispersions are unlike in description (nature), yet the dispersed fragments are not detectabJe by the human eye. This is due to the microscopic size of the particles in the solution. 3. The colour of the colloidal dispersion is determined by particles in the solution based on their size. The wavelengths of light that is absorbed will be longer ifthe size of the particle is large. 4. As a result of its size, the colloidal fragments can easily be passed through a traditional filter paper. However, these particles can be filtered by using membranes such as animal, cellophane, and ultrafilters. Give the name of membrane used for filteration ?
