Problem- A buffer contains 0.50 mol NH4+ and 0.50 mol NH3 diluted with water to 1.0 L. How many moles of NaOH are required to increase the pH of the buffer to 10.00? (pKa of NH4+ = 9.25)
Any Step by step help is greatly appreciated
The approximate molarity of this solution will be 0.025 M. You will take 10.0 mL of a 0.0100 M KIO3 solution, dissolve excess amounts of KI in it, and using the Na2S2O3 solution, titrate to the disappearance of the starch I2 color. Using the appro..
