- When mixing two aqueous solutions of
Na2CrO4 and AgNO3, a precipitate
and a soluble salt form according to the following equation.
Na2CrO4(aq)+AgNO3(aq)=Ag2CrO4+NaNO3
- Identify the precipitate and the soluble salt, using the
solubility rules. (2 pts)
Precipitate:
Soluble salt:
- Classify the species mentioned in the above equation as strong
electrolytes and weak electrolytes. (4 pts)
Strong electrolytes:
Weak electrolytes:
- Balance the above reaction and write the balanced formula
equation. Include the status of each product (solid or aqueous). (3
pts)
- Write the balanced total ionic and net ionic equations for the
above-mentioned reaction. (6 pts)
- An AgNO3 solution is added to 20.00 mL of 0.25 M
Na2CrO4 solution until the precipitate is no
longer formed (the maximum amount of precipitate has formed).
Determine the concentration of AgNO3 solution if 35.50
mL of AgNO3 solution is required to get the maximum
precipitate. (5 pts)
