Since you want to go from 5.0 M to 1.0 M concentration, and you want 225 mL of the resultant solution, you want to get 15 of the concentration. To balance a chemical equation, enter an equation of a chemical reaction and press the Balance button. The balanced equation will appear above. Fisher Scientific - This certified eluent concentrate for ion chromatography is traceable by potentiometric titration to NIST Standard Reference Material. Milliequivalents of HNO3 = 25 × 0.15 = 3.75 Milliequivalents of LiOH = 40 × 0.25 = 10 Therefore, the solution is basic.
