Why is it important to have a clean surface in surface studies?<\/strong><\/p>\n<p>Ans. A clean surface ensures accurate measurements of adsorption and catalytic properties, as impurities can interfere with surface reactions.<\/p>\n<p><strong>Q. Why is chemisorption referred to as activated adsorption?<\/strong><\/p>\n<p>Ans. Chemisorption involves a chemical reaction between the surface and adsorbate, often requiring activation energy to form strong chemical bonds.<\/p>\n<p><strong>Q. What type of solutions are formed on dissolving different concentrations of soap in water?<\/strong><\/p>\n<p>Ans. Dilute solutions form true solutions, while concentrated solutions form colloidal solutions known as micelles.<\/p>\n<p><strong>Q. What happens when gelatin is mixed with gold sol?<\/strong><\/p>\n<p>Ans. Gelatin stabilizes the gold sol by forming a protective layer around the gold particles, preventing their coagulation.<\/p>\n<p><strong>Q. How does it become possible to cause artificial rain by spraying silver iodide on clouds?<\/strong><\/p>\n<p>Ans. Silver iodide acts as a nucleating agent, causing water droplets to coalesce and form larger droplets that fall as rain.<\/p>\n<p><strong>Q. Gelatin, which is a peptide, is added to ice creams. What can be its role?<\/strong><\/p>\n<p>Ans. Gelatin acts as a stabilizer and thickener, preventing the formation of large ice crystals and improving the texture of the ice cream.<\/p>\n<p><strong>Q. What is collodion?<\/strong><\/p>\n<p>Ans. Collodion is a solution of nitrocellulose in ether and alcohol, used in medical dressings and photographic films.<\/p>\n<p><strong>Q. Why do we add alum to purify water?<\/strong><\/p>\n<p>Ans. Alum helps in coagulating and precipitating impurities, making them easier to remove from water.<\/p>\n<p style=\"text-align: center;\"><strong>Read More:<a href=\"https:\/\/infinitylearn.com\/surge\/study-materials\/ncert-syllabus\/class-12\/\"> NCERT Syllabus Class 12<\/a><\/strong><\/p>\n<p><strong>Q. What happens when an electric field is applied to a colloidal solution?<\/strong><\/p>\n<p>Ans. The colloidal particles move towards the electrode of opposite charge, a process known as electrophoresis.<\/p>\n<p><strong>Q. What causes Brownian motion in colloidal dispersion?<\/strong><\/p>\n<p>Ans. Brownian motion is caused by the random collision of colloidal particles with the molecules of the dispersion medium.<\/p>\n<p><strong>Q. A colloid is formed by adding FeCl3 to excess hot water. What will happen if excess sodium chloride is added to this colloid?<\/strong><\/p>\n<p>Ans. Excess sodium chloride will cause the colloidal particles to coagulate and settle out of the solution.<\/p>\n<p><strong>Q. How do emulsifying agents stabilize the emulsion?<\/strong><\/p>\n<p>Ans. Emulsifying agents form a protective layer around dispersed droplets, reducing the interfacial tension and preventing the droplets from coalescing.<\/p>\n<p><strong>Q. Why are some medicines more effective in the colloidal form?<\/strong><\/p>\n<p>Ans. Colloidal medicines have a larger surface area for absorption, improving their efficacy and rate of action.<\/p>\n<p><strong>Q. Why does leather get hardened after tanning?<\/strong><\/p>\n<p>Ans. Tanning introduces cross-links between collagen fibers in the leather, making it more durable and resistant to decomposition.<\/p>\n<p><strong>Q. How does the precipitation of colloidal smoke take place in a Cottrell precipitator?<\/strong><\/p>\n<p>Ans.
