D.4 / B.7 Calculating the pH of a buffer solution (SL / HL) - YouTube
A buffer solution was prepared by dissoving 0.02 mol propionic acid and 0.015 mol sodium propionate in enough water to make 1.00L of solution. (Ka for propoinic acid is 1.34 × 10^-5 ).
Calculate the pH of a buffer solution prepared by dissolving 30g of Na2CO3 in 500 mL of an aqueous solution containing 150 mL of 1M HCl . Ka for: HCO3 = 5.63 × 10^-11 [ log 133150 = - 0.05 ]
