the nature of acids, bases, and salts
... Many salts that do not themselves contain hydroxide ion act as bases by reacting with water to produce OH-. Sodium carbonate, Na2CO3, is the most widely used of these salts. When sodium carbonate is placed in water, the carbonate ion reacts with water CO32- + H2O → HCO3- + OHto form a hydroxide io ...

Effects of chemical pressure on the charge
... Nevertheless there has been no similar investigation devoted to correlating the variations of the CT bands with θ. The reason for this presumably lies in the high oscillator strengths of the CT bands (f ∼ 0.1–0.01) in comparison to the CF ones (f ∼ 10−4 ) making the CF spectrum easier to obtain in p ...
