hello, i have a question about polarity and SN1 reactions. If we have two solvent mixtures (ex: 2-propanol) but with different concentrations, would the higher concentration solvent be the more polar due to its higher concentration, meaning that there is an increase in number of molecules and collisions? And How can an SN1 reaction affect acid/basicity in a reaction. I don't understand how that can happen. HELP!
