Olutions that contain a weak acid, ha, and its conjugate base, a−, are called buffer solutions because they resist drastic changes in ph. when a solution contains a weak acid and its conjugate base or a weak base and its conjugate acid, it will be a buffer solution. for buffers containing a weak acid, the principal reaction is ha(aq)+h2o(l)⇌h3o+(aq)+a−(aq) unbuffered, a weak acid would ionize and the net reaction would proceed forward to reach equilibrium. however, when a significant amount of conjugate base is already present, the extent of the net reaction forward is diminished. thus, equilibrium concentrations of ha and a− are approximately equal to their initial concentrations. visualizing buffers you can visualize a buffer solution containing approximately equal concentrations of ha and a− in action using the following equation, where ka is the equilibrium constant: ka[h3o+]==[h3o+][a−][ha]ka[ha][a−] when the concentrations of ha and a− are relatively large, the addition of a small amount of acid or base changes their concentration negligibly. the result is that the ratio [ha]/[a−] maintains a value approximately equal to 1, and the [h3o+] is approximately equal to the ka value under buffer conditions. part a calculate the ph of the solution made by adding 0.50 mol of hobr and 0.30 mol of kobr to 1.00 l of water. the value of ka for hobr is 2.0×10−9. express your answer numerically

Achemist needs to determine the concentration of a solution of nitric acid, hno3. she puts 875 ml of the acid in a flask along with a few drops of indicator. she then slowly adds 0.800 m ba(oh)2 to the flask until the solution turns pink, indicating the equivalence point of the titration. she notes that 285 ml of ba(oh)2 was needed to reach the equivalence point. solution map in this titration, the concentration of base is known and can be used to calculate the unknown acid concentration: concentration of base ⟶ moles of base ⟶ moles of acid ⟶ concentration of acid part a how many moles of ba(oh)2 are present in 285 ml of 0.800 m ba(oh)2?
