solutions.
the amount added of HCl and NaOH are both 25mL.
the buffer solution is made of 2grams of NaC2H3O2 and
4 mL of 6M HC2H3O2 in a 50 mL solution (46mL of water). the
solution will contain 2.4x10^-2 mol each of NaC2H3O2 a d
HC2H3O2.

What is a buffer? • A buffer is a solution that, when introduced to a new environment, undergoes minimal pH change, typically when adding acidic or basic solutions. These are extremely important for life because the pH of human blood is delicate and even if it is changed by 0.1, there may be catastrophic effects. 2....
