An amphoteric salt is one that contains an anion that can act as either an acid or a base in water. baking soda, nahco3, is an example. by combining the ionization and hydrolysis reactions of the anion, you get the principle reaction that occurs when this salt is dissolved in water. 2hco−3(aq)↽−−⇀co2−3(aq)+h2co3(aq) 2 hco 3 − ( aq ) ↽ − − ⇀ co 3 2 − ( aq ) + h 2 co 3 ( aq ) the ph for such a solution is given by ph=pka1+pka22 ph = p k a 1 + p k a 2 2 where ka1 k a 1 and ka2 k a 2 are the ionization constants of the acid (in this case, h2co3). note that the ph of the solution is independent of the salt concentration. calculate the ph of a nahco3 solution.

Astable electron arrangement for an atom is one that does not easily change. how is this arrangement arrived at? a. valence electrons are transferred or shared to create a full outer shell of electrons. b. valence electrons are discarded into space to create a full outer shell of electrons. c. protons (positive charge) pair with valence electrons (negative charge) to create a strong bond. d. outer shells with valence electrons are transferred or shared.
