which of the following liquids would you expect to have the greatest surface tension and why?

a) molten sodium chloride because it is ionic and would have the strongest bonds of any of the liquids given

b) liquid carbon tetrachloride because it has the largest molecules of any of the liquids given

c) liquid water because it has the strongest h-bonding of any liquid

d) liquid hydrogen flouride because it has the strongest h-bonding of any liquid

e) all liquids would be expected to have the same surface tension

(i) adsorption is a surface phenomenon that causes the accumulation of molecules of a substance at the surface of a solid or liquid rather than in the bulk. in adsorption, the substance gets concentrated at the surface only. it does not penetrate through the surface to the bulk of the solid or liquid. for example, when a chalk stick is dipped into an ink solution, only its surface becomes coloured.


on the other hand, the process of absorption is a bulk phenomenon. in absorption, the absorbed substance gets uniformly distributed throughout the bulk of the solid or liquid. for example, when a sponge is dipped in water the whole sponge gets wets.


(ii)according to the schulze-hardy rule, the effectiveness of the salt causing flocculation depends on the charge on the ion of opposite sign to the charge on the sol particles. the greater the magnitude of the opposite charge, the higher the ability of a salt to coagulate the sol.  
thus, trivalent salt alcl3 is more effective in causing the coagulation of a negatively charged sol than divalent salt mgcl2.


(iii)out of sulphur sol and proteins, sulphur sol forms multimolecular colloids. sulphur sol consists of particles containing a thousand or more s8 molecules. on the other hand, proteins form macromolecular colloids. reno, please don't answer organic chemistry questions if you don't know the subject matter.
 
mixing acetic acid with sodium bicarbonate doesn't yield "gaseous water." also, you didn't actually answer the question and decided instead to list the first thing you found in wikipedia about a dangerous reaction that has nothing to do with the fact that acetic acid and hcl react the same way because they are both stronger acids than the conjugate acid of bicarbonate. there are many causes for swollen optic nerves, from increased pressure around the brain and optic nerves (intracranial hypertension), inflammation (optic neuritis), loss of blood flow (ischemic optic neuropathy), etc. a spinal tap can determine if the pressure around your brain is high, but the rest of your spinal fluid tests can be normal. ask your doctor about your diagnosis and treatment. see more... solid + liquid mixture : sand and water, charcoal and water. Tin(II) chloride can dissolve in less than its own mass of water without apparent decomposition, but as the solution is diluted, hydrolysis occurs to form an insoluble basic salt:

 

Therefore, if clear solutions of tin(II) chloride are to be used, it must be dissolved in hydrochloric acid (typically of the same or greater molarity as the stannous chloride) to maintain the equilibrium towards the left-hand side (using Le Chatelier's principle).
