What mass of silver chloride can be prepared by the reaction of 100.0 mL of 0.20 M silver nitrate with 100.0 mL of 0.15 M calcium chloride? Calculate the concentrations of each ion remaining in solution after precipitation is complete.
Interpretation:
The mass of Silver chloride and concentration of each ion after the precipitation reaction has to be determined.
Concept Introduction:
The mass of a compound can be calculated using the molar mass of the compound to the given moles. It can be given by the equation,
Concentration of a solution can be defined in terms of molarity as the ratio of moles of solute to the volume of the solution.
Answer to Problem 62E
The mass of Silver chloride produced is
The concentration of individual ions were found to be
Explanation of Solution
Volume of Silver nitrate =
Molarity of Silver nitrate =
Volume of Calcium chloride =
Molarity of Calcium chloride =
The volume and molarity of Silver nitrate are recorded along with volume and molarity of Calcium chloride as shown above.
Calculate for the mass of Silver chloride is explained as follows,
Molar mass of Silver chloride=
The chemical equation for this precipitation reaction can be given as,
Concentration of each ion in remaining solution:
Volume of Silver nitrate =
Molarity of Silver nitrate =
Volume of Calcium chloride =
Molarity of Calcium chloride =
The volume and molarity of Silver nitrate are recorded along with volume and molarity of Calcium chloride as shown above.
Calculation for the concentration of
The concentration of each ion can easily be determined from the moles of each reactant.
Similarly,
To get
Concentration of
The concentration of
Calculation for the concentration of spectator ions is as follows,
Concentration of
Concentration of
The concentration of the spectator ions is calculated by plugging in the values of molarities and volumes of Calcium chloride and Silver nitrate. The concentration of

- The concentration of a certain sodium hydroxide solution was determined by using the solution to titrate a sample of potassium hydrogen phthalate (abbreviated as KHP). KHP is an acid with one acidic hydrogen and a molar mass of 204.22 g/mol. In the titration, 34.67 mL of the sodium hydroxide solution was required to react with 0.1082 g KHP. Calculate the molarity of the sodium hydroxide.arrow_forwardA 8.50 g sample of KCl is dissolved in 66.0 mL of water. The resulting solution is then added to 72.0 mL of a 0.280 M CaCl2(aq) solution.
