The explanation corresponding to the given statement that a mixture of an ammonia and ammonium chloride behave as a buffer when dissolved in water is to be stated. Concept introduction: A solution that consists of a mixture of a weak base and its conjugate acid, or vice versa is known as buffer solution. Buffer is a solution that has the ability to resist changes in pH when bases or acids are added. The value of pH ranges from 0 to 14 . Higher is the concentration of hydronium ion; lower is the value of pH .

4 A chemistry graduate student is given 100. mL of a 0.50M methylamine (CH,NH,) solution. Methylamine is a weak base with K,=4.4 × 10 *. What mass of CH,NH,Cl should the student dissolve in the CH, NH, solution to turn it into a buffer with pH = 10.93? You may assume that the volume of the solution doesn't change when the CH,NH, Cl is dissolved in it. Be sure your answer has a unit symbol, and round it to 2 significant digits. olo Ar x10

consider the titration of 50.0 mL of 0.10 M acetic acid with NaOH. drag and drop each amount of NaOH added (to the acetic acid) Into the appropriate resulting pH. In other words, determine the pH of the final solution after each volume of NaOH has been added. Will the resulting solutions be acidic, basic, or neutral? Consider the stration of 50.0 ml of 0.10 M acetic acid (HC₂H₂O₂. K, -18 x 10) with NaOH. Drag and drop each amount of NaOH added to the acetic acid) into the appropriate resulting pH.
