Question | Answer |
The pH of a solution can be stabilized by the addition of a [...]. | The pH of a solution can be stabilized by the addition of a buffer. |
A buffer is typically a mixture of an acid and its [...] or a base and its [...]. | A buffer is typically a mixture of an acid and its conjugate base or a base and its conjugate acid. |
In the human body, the [...] of blood is partially controlled by a buffer of carbonic acid (H2CO3) and bicarbonate (HCO3- ). | In the human body, the pH of blood is partially controlled by a buffer of carbonic acid (H2CO3) and bicarbonate (HCO3- ). |
Titration is a procedure that allows you to determine the [...] of an unknown solution | Titration is a procedure that allows you to determine the pH of an unknown solution |
During a titration, the standard solution (the known one) is slowly added to the unknown solution until a [...] change indicates that it's been neutralized. | During a titration, the standard solution (the known one) is slowly added to the unknown solution until a color change indicates that it's been neutralized. |
titrating solution 1 with solution 2: This means that solution [...] is the unknown that is in the flask. The titrant, solution [...] in the burette, is the standard solution, whose pH is known. | titrating solution 1 with solution 2: This means that solution 1 is the unknown that is in the flask. The titrant, solution 2 in the burette, is the standard solution, whose pH is known. |
the [e-] point: This is the point at which the solution in the flask is a neutral solution | the equivalence point: This is the point at which the solution in the flask is a neutral solution |
