Consider the chemical reaction that occurs when 30.0 mL of 0.1 M Ca(NO3)2 and 15.0 mL of 0.20 M Na3PO4 are mixed and allowed to react. After the reaction has run to completion, which of the following ions will be present in the solution in the LOWEST concentration.

  • a. Na+ b. NO3- c. Ca2+ d. PO43- e. Both Ca2+ and PO43- will be present in the same concentration. Susanne commented over 3 years ago
