For 10.0 milliliters of the NH3, 20.0 milliliters of 0.100-molar HCl solution was required. What was the concentration of NH3 originally? NH3 + HCl ( NH4+ + Cl– 0.0200 L HCl x 0.100 mol HCl x 1 mol NH3 = 0.00200 mol NH3 1 L HCl 1 mol HCl 0.00200 mol NH3 = 0.200 M NH3. 0.0100 L NH3 (no calculator needed if done step-by-step) 9.

5. Once the value has stabilized, press [Trigger] on the CBL and enter the molar concentration of solution 1 in the TI-83+ calculator. Enter the value in exponential form: 1.00x10-3 as 1.00E-3. Press [ENTER]. You have now saved the first data pair for this experiment. A graph will be displayed on the calculator screen. 6.

The graph of pH vs Molar concentration is logarithmic. The analysis on my calculator gave me the following relation: Y = 2.5486 + (-0.2337 ln X) where Y is pH and X is Molarity. This means that the pH decreases as the concentration of the acid increases. This relation has a limited application as maximum acid concentration is 12 to 14 M
