A student prepares a 100.0-mL buffer solution that is 0.200 M in hydrofluoric acid and 0.200 M in sodium fluoride. How many grams of sodium hydroxide should be added to the buffer solution to change its pH to 4.00? (Assume no volume change upon adding the sodium hydroxide). I'm seeking the detailed work in finding the solution to this problem. Many thanks!
The acetic acid/acetate buffer system is a common buffer used in the laboratory.
The acetic acid/acetate buffer system is a common buffer used in the laboratory. Write the equilibrium equation for the acetic acid/acetate buffer system. The formula of acetic acid is CH3CO2H. equilibrium equation: Which way does the equilibrium shift if more H3O+ is added? The equilibrium will not change. The equilibrium will shift to the left. The equilibrium will shift to the right. Which way does the equilibrium shift if more OH- is added? The equilibrium will shift to the right. The equilibrium will shift to the left.
