Preparing and diluting solutions lab answers
WebAs seen in the equation above, the pH of the buffer solution is only dependent on the amount of acid and conjugate base components present in the solution. That is why during the pH adjustments, drops of a strong acid or strong base were used. Hence, diluting the buffer solution with water does not affect the pH value of the buffer solution. 4.
