If a buffer solution is 0.220 M in a weak acid (Ka = 8.5 × 10-5) and 0.550 M in its conjugate base, what is the pH?
Determine the volume of 0.M baryta (Barium hydroxide is the chemical compound with the formula Ba(OH) 2 ) that is needed to neutralize 35 ml of 0.2M phosphoric acid (H 3 PO 4 ), ?
you want a solution that will buffer the addition of either 10 micro moles of acid or 10 micro moles of base. total buffer concentration is equal to the concentration of the acid plus the concentration of salt in the acid. which of the following b..
