- A 0.879 g sample of a CaCl22H2O/K2C2O4·H2O solid salt mixture is dissolved in ~100 mL of deionized water. The precipitate, after having been filtered and air-dried, has a mass of 0.284 g. The limiting reactant in the salt mixture was later determined to be CaCl2·2H2O.
- Write the ionic equation for the reaction.
- Write the net ionic equation for the reaction.
- How many moles and grams of CaCl22H2O reacted in the reaction mixture?

The person measures 100 mL of stock NaOH(aq) solution into a buret but forgets to write down its concentration. They then measure out 50.0 mL of unknown H3PO4(aq) solution (which has an indicator) and places this solution in a constant-pressure calorimeter for the titration experiment. The initial temperature of all the solutions is 22.9 Celsius. The student adds 46.84 mL of NaOH(aq) from the buret to the H3PO4(aq) solution in the calorimeter to reach the equivalence point (color change for indicator). The final solution temperature is 33.5 Celsius.
