Coagulation and Protection of Colloidal Solution - Class Notes
Web17 de mar. de 2024 · Let us understand Hardy Schultz rule, According to this rule greater the valency of the coagulating ion, greater is the power to cause precipitation. Active ion is responsible for coagulation. Coagulation or flocculating value is the minimum concentration of electrolyte in millimoles required to cause coagulation of one litre of colloidal solution. Web11 de abr. de 2024 · Hint: Flocculating value or the coagulating value is the amount of the electrolyte which is needed so that 1 litre of colloidal solution precipitates easily. The coagulating power or flocculating power is the reciprocal of coagulating value or flocculating value. Complete step by step solution:-Colloidal solutions are those types of … Web4 de out. de 2024 · has maximum coagulating power with ferric hydroxide sol. Explanation: The anions present are , , and . According to Hardy Schulze rule:. 1. The effective ions of the electrolyte in bringing about the coagulation are those which carry opposite to that of the colloidal particles. these ions are called coagulating ions or flocculating ions. fishing jobs in new zealand
