A solution of a weak acid, like acetic acid (CH 3COOH) is titrated with a strong base, like a solution of Sodium Hydroxide (NaOH). At the equivalence point is:a. the pH = 7 b. the pH is higher as 7 c. the pH is lower as ... WebIn this particular instance, this would also be the neutral point of the titration, because sodium chloride solution has a pH of 7. But that isn't necessarily true of all the salts you might get formed. For example, if you titrate ammonia solution with hydrochloric acid, you would get ammonium chloride formed. streaming macbook to ps4

Acid–base titration - Wikipedia

WebIn a weak base-strong acid titration, the acid and base will react to form an acidic solution. A conjugate acid will be produced during the titration, which then reacts with water to form hydronium ions. This results in a solution with a pH lower than 7. WebCalculating pH for Titration Solutions: Strong Acid/Strong Base A titration is carried out for 25.00 mL of 0.100 M HCl (strong acid) with 0.100 M of a strong base NaOH (the titration … streaming machineWebI've read that phenolphthalein changes color when the pH is from above the range of 8.3 to 10.0 Conclusions: 1: Using it we have the change in color when we have more OH- than those used to neutralize the strong acid. 2: As the range is from 8.3 to 10.0, we would have an error margin of about 2 decimal points in the total concentration of H+ • row data sheet
