Question
A student wishes to prepare a solution with a final concentration of Na+ = 0.50 M and a final concentration of HCO3– = 0.10 M by taking some NaOH and some trona (Na2CO3•NaHCO3•2H2O) and diluting with water to a final volume of 1.00 L. How much NaOH and trona are required?
A.✓ Correct
0.05 mol NaOH, 0.15 mol trona
B.
0.20 mol NaOH, 0.10 mol trona
C.
0.35 mol NaOH, 0.05 mol trona
D.
A solution cannot be prepared with the desired concentrations of Na+ and HCO3– using only NaOH and trona.
