A drop of NaOH titrant adheres to the side of the buret between the initial and final readings for the titration.As a result of the `clean glass`error, will the molar concentration of the NaOH solution be reported as too high or too low? Explain.
Assume 40 g of solid (NH4)2Fe(SO4)2 * 6H20 was used in 1 l of solution to create the solution tested. What is the theoretical % Fe in a pure sample. Assume that the molecular wt = 392.15 g/mole.
lda is added to a solution containing ethyl butanoate. after thisreaction has gone to completion propanal is added.
Iodine does not have a permanent dipole and is therefore a non-polar molecule. Why Iodine does not have a permanent dipole a) electronegativities of two iodine atoms are identical b) two iodine atoms will cause partial charge separation
