What is flocculation power?
What is flocculation power?
The precipitation of colloidal solution, with the help of addition of excess of an electrolyte is known as flocculation or coagulation. The electrolyte is known as flocculating agent, and the power of an electrolyte to precipitate a colloidal solution is known as flocculating power.
Which has minimum flocculation power?
Flocculation value is inversely proportional to coagulating power of the ion . As, Pb4+ has high charge its coagulating power will be maximum and will have minimum flocculation value.
Which of the following has maximum flocculation?
Fe(OH)3 is positively charged. Hence Cl- ions with minimum opposite charge will have maximum flocculation value (minimum cagulating power).
Which of the following ions has the highest flocculating power for the coagulation of the positive charged Sol?
For coagulating of positively charged sols, [Fe(CN)6]^4 – ion has higher coagulating power than that of PO4^3 – , SO4^2 – , Cl^- .
How does flocculation occur?
In dispersed clay slurries, flocculation occurs after mechanical agitation ceases and the dispersed clay platelets spontaneously form flocs because of attractions between negative face charges and positive edge charges.
Which of the ion has minimum flocculation value?
Among the four electrolytes, NaCl has the lowest coagulating power, so its flocculation value will be maximum.
What is flocculation value?
The minimum concentration of an electrolyte required to cause coagulation of a sol is called its flocculation value. It is expressed in millimoles per litre.
Which ion has maximum precipitation flocculation value?
Which of the following electrolyte will have maximum?
Which of the following electrolytes will have maximum coagulating value for Ag//Ag^(+) sol? According to Hardy-Schuize law, greater the charge on anion greater will be its coagulating power. Here,PO3-4 have highest charge. Hence, PO43 have highest coagulating power.
Which ion has highest precipitation power?
Answer: (a) Al^3 has highest precipitation power.
What is flocculation biotechnology?
Flocculation is used in biotechnology applications in conjunction with microfiltration to improve the efficiency of biological feeds. The addition of synthetic flocculants to the bioreactor can increase the average particle size making microfiltration more efficient.
