It is required to titrate ethanol solution .Being available a 0.2mol/l potassium dichromate solution and 4mol/l sulfuric acid solution on the presence of a convenient indicator.
a)indicate the glassware used for titration.
b)give a brief description of the procedure followed .How do we detect the equivalence point?
c)write the half reaction and the equation of the overall redox reaction.
d)the titration of 10ml of aqueous ethanal solution required 15ml of dichromate solution to reach the equivalence point .
Calculate the molar concentration in g/l of ethanol solution.
e)50ml of ethanal solution we heated with an excess of an ammonical silver nitrate solution.
I)write the half reaction and the equation of the overall reaction.
II)what mass of solid is formed due to the reaction?
THANK YOU FOR YOUR HELP!
