How do pH, propionic acid, and propionate change when HCl, a strong acid solution, with a final concentration of 0.0005 mole/L, is added to the solution containing 10-3 M sodium propionate? HCl is added from a concentrated stock solution, so the volume change is negligible.

I'm not sure about how I'm supposed to find NaOH concentration from a strong acid and strong base titration. I'm thinking that 2.5×10^-8 mol per L that I calculated would make the moles of NaOH 2.5x10^-8 mol since it's a one to one ratio. Hydrochloric acid titration: Confirming the concentration of NaOH Concentration of HCl solution from the stock bottle: _ 0.OSM! Initial pH of HCl solution: 1.66 pH Volume NaOH (mL) Concentration of NaOH (M) Non Phenolphthalein (end point)...
