Consider the reaction that you did to deprotonate vanillin using sodium hydroxide. If the pKa of vanillin is about 7.4, what is the equilibrium constant for the reaction of vanillin with sodium hydroxide to make the conjugate base of vanillin?
Write out the balanced equation, add arrows to show the mechanism of the reaction, and show your work/calculation(s).

Bleach (sodium hypochlorite, NaOCl) is produced by the
reaction of a sodium hydroxide solution with chlorine gas. Water
and NaCl are also produced in the reaction.
1.75 liters of a 45% NaOH solution (S.G = 1.478) is
reacted with 275 liters of gaseous Cl2 (at STP). The product is
analyzed and it is determined that 618 g of NaOCl was formed.
Determine:
The limiting reactant.
The percent excess of the excess reactant, if any.
The conversion.
The yield of NaOCl.

160 g of a 0.80% sodium hydroxide solution.
The following question involves the reaction of sodium hydroxide
and succinic acid. Succinic acid is diprotic: the acid
(H2C4H4O4) reacts with
two of its hydrogens to give
C4H4O42-. The balanced
“molecular” equation for the reaction has coefficients of 2 for
NaOH and 1 for succinic acid:
2 NaOH (aq) +
H2C4H4O4 (aq) -->
Na2C4H4O4 (aq) + 2
H2O (l)

A student added 10 g (0.25 mol) of sodium hydroxide to 40 cm3 of water to make a concentrated solution. All the sodium hydroxide dissolved. He measured the maximum temperature rise. He suggested that these results would give an accurate value for the standard enthalpy change of solution. Give two reasons why he is incorrect.
