AI Thread Summary
The discussion centers on how hydrophobicity, surface charge, and the addition of salts like NaCl, NaNO3, and NaSCN affect the electrophoretic mobility of a substance dispersed in water. The presence of salts leads to a more compact structure, with hydrophobic regions internalized and hydrophilic regions exposed, which enhances mobility. The order of salt effectiveness is influenced by their ionic strength and specific interactions with the charged surface. Hydrophilic substances with negative charges tend to be more stable in saline environments compared to hydrophobic ones, which can aggregate. Overall, the type of salt and the nature of the substance's charge significantly impact its stability and interaction dynamics.

suppose we have a substance that is hydrophobic/hydrophilic and also has some charge on it surface(negative or positive) disspersed in water. if we add some salt different kinds possible(NaCl NaNO3 NaSCN). What is the effect of hydrophobicity and surface charge on Electrophoretic mobility?
 
Chemistry news on Phys.org


Salts will cause the substance to adopt a more compact structure with the hydrophobic bits internalized and the hydrophilic bits exposed. It should move faster/farther.

but i want a explanation for the order of salts, which one acts more strongly?, and what is the difference between hydrophilic/hydrophobic dispersed substance with negetive/positive charge on its surface regarding their stability,how they interact with diffrent salts.
 

Thread 'Humidity of a saturated NaCl solution with anticaking additive'

I want to test a humidity sensor with one or more saturated salt solutions. The table salt that I have on hand contains one of two anticaking agents, calcium silicate or sodium aluminosilicate. Will the presence of either of these additives (or iodine for that matter) significantly affect the equilibrium humidity? I searched and all the how-to-do-it guides did not address this question. One research paper I found reported that at 1.5% w/w calcium silicate increased the deliquescent point by...
