The small bubbles that form on the bottom of a water pot that isbeing heated (before boiling) are due to dissolved air coming outof solution.
Why does aluminum hydroxide readily dissolve in concentrated NaOH but not in concentrated NH3? Please give a thorough explanation, not just a short answer.
From the following chemical reactions determine the relative Bronsted-Lowry acid strengths (strongest to weakest). HCLO4 (aq) + H2O (l) ----> H3O (aq) + ClO4- (aq)

A lactic acid/lactate ion buffer solution contains 0.29 M HC3H5O3- and 0.80 , respectively. The Ka value of lactic acid is 1.4x10^-4. Calculate the pH of the buffer.
The Ka values for nitrous acid HNO_2 and hypochlorous HClO) acid are 4.5 10^{-4} and 3.0 10^{-8}, respectively. Which one would be more suitable for use in a solution buffered at pH = 7.0?
For 500 mL of phosphate buffer with 0.5 M of H3PO4 and 0.3 M NaH2PO4 calculate acidic and basic buffer capacity. How much of strong acid should be added to shift buffer pH one unit down, and how much of the strong base is needed
One of the treatments for gangrene and the bends, is hyperbaric oxygenation. This occurs in a chamber in which oxygen is used at higher-than-normal pressures.
