Titanium reacts with hydrogen peroxide in 1.00 M sulfuric acid to form a colored complex. If a 2.00x10^-5 M solution absorbs 31.5% of the radiation at 415 nm, what would be: the absorbable, the transmittance, and the percent absorption for a 6.00x10^-5 M solution?
Do these lambda maxs indicate an increase or a decrease in the energy of the light absorbed as the number of EN ligands bound to Cu(II) increases
Salicylic acid reacts with acetic anhydride at the phenol group rather than at the carboxylic acid group. Briefly explain why the phenol site is preferred over the carboxylic acid site.
