Write a balanced ionic equation for 1) the first acid-base
reaction of maleic acid and sodium hydroxide, 2) the second
acid-base reaction between C4H3O4-and sodium hydroxide. Finally 3)
add the two equations together and cancel out spectator ions to get
a net ionic reaction.
In each case write the chemical equation which describes the
relevant acid-base reaction before you start the mathematics. What
are the exact pHs of: A. 10^-2 M acetic acid B. 5 x 10 -2 M sodium
acetate C. 10^-3 M pyridinium chloride Please show the steps so I
can understand how to do it.
