THIS USER ASKED 👇
A buffer solution is all of the following EXCEPT: a solution that contains both a weak acid and its conjugate base. a solution that resists a change in pH when a base is added. a solution that regulates pH because it is such a strong acid or base. a solution that resists a change in pH when an acid is added. All of the above are true.
THIS IS THE BEST ANSWER 👇
INTRODUCTION pH REGULATING IT IS FREE ACID OR BASE
A buffer solution is an aqueous solution consisting of a weak acid and its conjugate base. It is an aqueous solution used to maintain the pH of the solution at an almost constant value in various chemical processes. Represents the change in pH when a strong acid or solid base is added. It is therefore essential in various chemical applications and even in the human body because the bicarbonate buffer system maintains an almost constant value of blood pH in conjunction with the kidneys. The buffer solution is able to maintain this almost constant range of values due to the balance between the weak acid and its conjugate base. So the wrong statement in the choices is that a buffer solution that controls pH is a solution because it is such a strong acid or base. The other options are right.
