WebNov 20, 2024 · The acid dissociation constant, Ka, for benzoic acid, C6H5CO2H, equals 6.5 x10 -5 . If you wish to make a buffer of pH 4.0 using 10.0 mL of 0.100 M C6H5CO2H, calculate the number of mL of 0.100 M sodium benzoate, … WebSo, 50.0 mL would be 0.0500 liters. So this would be 0.0500 liters. Once again, solve for moles. So, 0.200 times 0.0500 gives us 0.0100 moles of acetic acids. So notice we have the same number of moles of acid as we do of base. And the base is going to neutralize the acid. Let's go ahead and write the reaction.
