18. On the basis of Hardy-schulze rule explain why the coagulating power of phosphate is higher than chloride ? ... greater is its power to cause precipitation (Hardy-Schulze rule). In a sentence this rule state as “Greater is the valency of the oppositely charged ion of the electrolyte being added, the faster is the coagulation”. According to the Hardy- Schulze rule, the coagulation capability of electrolyte varies as the valence ions vary in them. NCERT RD Sharma Cengage KC Sinha. 19. Question: What is meant by term Broadspectrum antibiotic, Give example? what is hardy schulze rule ? • Flocculation value: The coagulating power of an electrolyte is usually expressed in terms of its flocculation value which may be defined as the minimum concentration (in millimoles per litre) of an electrolyte required to cause the coagulation of a sol. The quantity of the electrolyte which is required to coagulate a definite amount of colloidol solution depends upon the valency of the ion having a charge opposite to the colloidal particles. Application of colloids and emulsions in daily life. Thus, the modified Hardy-Schulze law can be stated as ‘the greater the polarising power of the flocculating ion added, the greater is its power to cause precipitation.’ Previous Question Next Question Popular Questions of Class 12th chemistry Showing posts with label hardy schulze rule class 12. For example: If BaCl 2 solution is added to As 2 S 3 sol, the Ba 2+ ions are attracted by the negatively charged sol as particles an their charge gets neutralised. State Hardy Schulze rule. Reason : Cleansing action of detergents involves the formation of micelles. Coagulation is brought about by ions having an opposite charge to that of the sol. The required amount of electrolyte for the coagulation of a definite quantity of colloidal solution is dependent on the valency of the coagulating ion (which is the ion that holds a charge which is opposite to the charge of the colloidal particles). The coagulation of the lyophobic sols can be carried out by following methods. This leads to coagulation. About Us. This effect is known as tyndall effect. (vii) Give structure of monomer unit of Nylon-6. Show all posts. Adsorption The accumulation of molecular species at the surface rather than in the bulk of a solid or liquid is termed adsorption . Negatively charged particles move towards the cathode and Positively charged particles moves towards anode. Why Ammonia is used to prepare glass cleaner instead of Caustic Soda? A simple and inexpensive experiment for verifying the schulze hardy rule. The efficient ions of the electrolyte in bringing about coagulation are those which hold charge reverse to that of the colloidal particles. 2.6k SHARES. Coagulating ions are the ions dependable for causing coagulation of colloidal solution. According to hardy schulze rule greater the valency of the active ion or flocculating ion greater will be its coagulating power. 1 answer. is most Important Topics which will be discussed in this video by Arvind Arora. Emulsions, surfactants, micelles (only definition and examples). Saameer Mody. All rights reserved. These ions are called coagulating ions. Ended on Aug 25, 2020. Hindi Chemistry. © copyright 2020 QS Study. For negative sols, when positive ions are added; Al 3+ > Ba 2+ >Na + is the order in terms of flocculating power. According to Hardy Schulze rule arrange the following in increasing order of coagulating power. (c) How many isomers are there for octahedral complex, [CoCl 2 (en)(NH 3) 2] + ? Question: Name the two components of starch. Hardy-schulze rule sates that :- Hardy-schulze rule sates that :- Books. Question: What is the co-ordination number of … Schulze Hardy Rule. 2.6k VIEWS. Reason: Greater the valency of the flocculating ion added, greater is its power to cause precipitation (Hardy Schulze rule). 9 years ago | 1.7K views. Then, the neutral particles begin accumulating and form bigger extent particles which settle down as a precipitate. Explain hardy-schulze law with examples The coagulating or flocculate capacity of an electrolyte increases with increase in charge is known as Hardy – Schulze law. Course. ... XII Chemistry Question Paper - 11- CBSE Board QP 2012 set 2 . (b) Brownian Movement : Zig-zag motion of colloidal particles. Thus, the modified Hardy-Schulze law can be stated as ‘the greater the polarizing power of the flocculating ion added, the greater is its power to cause precipitation.’. Surface Chemistry. (b) Define spectrochemical series. Watch Now. NCERT DC Pandey Sunil Batra HC Verma Pradeep ... Maths. Reason: Cleansing action of detergents involves the formation of micelles. Click hereto get an answer to your question ️ Q104.Hardy-Schulze rule explains the effect of electrolytes on the coagulation of colloidal solution. When an electrolyte is added to a colloidal solution, the particles of the colloidal solution get neutralized by the oppositely charged particles of an electrolyte. Assertion : Detergents with low CMC are more economical to use. Share. Thus, Hardy-Schulze law can be modified in terms of the polarising power of the flocculating ion. Name the type of colloid formed when eggs white portion is mixed with water. These ions can be referred to as flocculating ions or coagulating ions. According to Hardy-Schulze rule, greater the valency of the active ion or flocculating ion, greater will be its coagulating power. Explain what is observed when. (a) Why are low spin tetrahedral complexes rarely observed? Hardy Schulze Rule. Your email address will not be published. Alleen Test Solutions. The coagulation capacity of different electrolytes is different. Sulekha Rani.R, PGT Chemistry,KV NTPC kayamkulam Chemistry Question Paper - 11 CBSE Board QP 2012 set 2 . For example, coagulation power series of Al 3+, Na + and Ba 2+ is Al 3+ > Ba 2+ > Na +. According to Hardy - Schulze rule "Greater is the valency of ions, greater is its power to bring about coagulation. 6. Question 16. The concentration of adsorbate increases only at the surface of the adsorbent. The lesser the size of an ion, the more will be its polarizing control. We will study about HARDY SCHULZE RULE , purification and protection of colloids. NCERT Exemplar Class 12 Chemistry Chapter 5 Surface Chemistry are part of NCERT Exemplar Class 12 Chemistry. Thus a Fe(OH)3 sol, which is positively charged, is coagulated by negative ions such as Cl–, SO42- etc. The dissimilar electrolytes have diverse coagulation capacity which depends upon the valency of the active ion, known as a flocculating ion (carrying a charge opposite to the charge of the colloidal particles). Revise-athon Day 3 Redox Reactions & Elecrochemistry. Download PDF's. The quantity of the electrolyte which is required to coagulate a definite amount of a colloidal solution depends upon the valency of the coagulating ion(ion having a charge opposite to that of the colloidal particles). Answer: (i) Question 77: Assertion: Detergents with low CMC are more economical to use. Schulze hardy rule. A lyophillic colloid which is used to protect lyophobic colloid from electrolyte and from getting coagulated is called protective colloid. ISC Class 12 Chemistry Syllabus 2020-21.
