3. Calculating the number of moles per ion<br />
Example How many moles of each ion are present in 1.25 L of<br />
0.250 M Na 3 PO 4 solution?<br />
4. Stoichiometry of Solution Reactions<br />
Example One way to determine the amount of chloride ion in a water<br />
sample is to titrate the sample with st<strong>and</strong>ard AgNO 3 solution to produce<br />
solid AgCl according to this reaction: Ag + (aq) + Cl (aq) AgCl (s)<br />
If a 25.0 mL water sample requires 27.2 mL of 0.104 M AgNO 3 in such a<br />
titration, what is the concentration of Cl in the sample?<br />
