4. How many moles of acetic acid must be added to 250.0 mL of a 1.62 Macetate solution to make a buffer with an [H,0') of 1.0 x 10' M (pH of 7.00)? The equilibrium constant, K., for acetic acid is 4.28 x 10'. Assume adding mole acetic acid does not change the volume of solution. of Show the steps in your calculation. Answer
How many moles of solid sodium acetate (CH3COONa) would you need to add to reduce the percent ion...
How many moles of solid sodium acetate (CH3COONa) would you need to add to reduce the percent ionization of a 0.20 M solution of acetic acid (CH3COOH) to 0.0060%? The volume of the acid solution is 2.00 L and you can ignore the slight change in volume that comes from adding the solid sodium acetate. (Hint: remember that you can make the assumption that the change in molarity is small)
