Question:
1. Sodium phosphate dissociates when it dissolves inwater.
Na3PO4(aq) --> 3Na+(aq) + PO43-(aq)
If the concentration of theNa3PO4 solution is 0.033 mol/L,what is the concentration of the sodium ions?
a. 0.011 mol/L
b. 0.033 mol/L
c. 0.066 mol/L
d. 0.099 mol/L
2. Scandium sulfate,Sc2(SO4)3(aq),dissociates when it is dissolved in water.
- Write the dissociation equation.
- If the concentration of Sc2(SO4)3 (aq) is 0.19 mol/L,calculate the concentration of the scandium ions.
- If the concentration of Sc2(SO4)3 (aq) is 0.19 mol/L,calculate the concentration of the sulfate ions.
