Analysis
1. Which sample of water do you think contains the most chloride
ions? Explain your reasoning.
2. Find the average volume of AgNO
3
used for each sample by adding
the volume from both trials and dividing by 2. Record the average on
the data table.
3. Use the average volume of AgNO
3
for each sample and the
compound's
molarity
(0.1 M) to determine the number of moles of
AgNO
3
used. The formula for molarity is:
molarity (M) =
moles
volume (L)
Record your calculation on the data table.
4. Write the balanced chemical equation for the reaction of chloride
ions with silver ions to form silver chloride. What is the mole ratio
for silver and chloride?
5. Using the mole ratio of silver to chlorine, determine the mole of
chloride contained in each sample.
