a) To the 1.0 M HCl solution, add a few grains of NaCl, stir/dissolve salt and record new pH. |
b) To the 1.0M HC2H3O2 solution, add a few grains of Sodium acetate ( NaC2H3O2), stir/dissolve and record new pH. c) To the 1.0M NaOH solution, add a few grains of NaCl, stir/dissolve salt and record new pH. d) To the 1.0M NH4OH solution, add a few grains of Ammonium chloride ( NH4Cl ), stir/dissolve and record pH. |
Question for 2018-2018 AP Chem Extension. (Will answer these questions on different sheet of paper) |
1. What would LeChatlier's Principle about adding NaC2H3O2) to a HC2H3O2 solution? What would the new Equilibrium "bucket" look like and do any concentrations change? Do those changes the pH of the new solution compared to the original solution? |
2. Similarly, how would the same thing happen when you added NH4Cl to the NH3 ( i.e. NH4OH solution). |
|
3. Does the same thing happen when added the NaCl to either the HCl solution and/or NaOH solution? Explain? |
