Hi there,
Could you please help me with the following problem:
I would like to have a table for the following acids pH (or Ka acidity constant)
HX(cl,br,i,f), hno3, h2s, h2so4(2 values, also for hso4-), r-cooh in general, hcn, nh4, Ar-oh(fenols), R-oh (alcohols) , and water (which i think it is situated between alcohols and fenols)
besides this, i also have some questions, i hope you can help me:
1.
if we have a reaction betwenn sulfuric acid and water, it`s an exotermic one, why do we hace to cool it to improove the reaction, because if we have a higher temperature that means the molecules will hit harder and react more.
i know this is the oppesite of an endotermic reaction, that if we heat it than will reac better, giving energy for breaking the bonds, but i can`t figure it out for the exotermic one.
2.
do ionic compounds (such as salts) solvate in alcohols? (if not, why only in water)
3.
what happens with the co2 from mineral water if we cool it under 0 degrees celsius, regarding the solubility of co2 (rises, lowers, the same?)
4.
a supersaturated solution means that in a solution we have more substance (e.g. NaCl) than the solution (e.g. H2O) can solvate
5.
could ytou please tell me where can I fiind some good articles about acids\bases OR about the solubility of substances and what ifluences it
thank you
please excuse my spelling errors
