So let's go ahead and do that. (b) Assuming that you have 50.0 mL of a solution of aniline I thought the acetate was a strong conjugate base( because acetic acid is a weak acid), I used the to the strong base way of calculate the pH. This correlation derives from the tendency of an acidic substance to cause dissociation of water: the higher the dissociation, the higher the acidity. This is similar to the reason why the chloride ion (and the sodium ion) in NaCl does not affect the pH of the solution. Is an aqueous solution with pOH = 4.78 acidic, basic, or neutral? Next, we think about the change, and since NH4+ turns into NH3, whatever we lose for NH4+ is what we gain for NH3. %%EOF 1 answer; geometry; asked by Anonymous; 383 views; Two groups of students are asked to depict a picture of a semi-circular pizza.
