2. Suppose you add 35.6 mL of a 0.25 M NaOH solution to an acid solution to reach the endpoint of a titration. The acid solution was prepared by dissolving 0.50 grams of an
acid in a mixture of water and ethanol. One mole of acid (HA) will react with one mole
of NaOH as described by the following chemical equation.
HA (aq) + NaOH (aq)
NaA (aq) + H20 (1)
Complete the table below based on this data.
How many moles of How many moles of acid
NaOH were added during reacted during this

titration?
moles = liters of NaOH X hint: this is equal to the
molarity of NaOH
number of moles of NaOH added
What is the formula
weight of the acid in
grams/mole?
FW - acid mass / moles of acid
