Let us use an acetic acid-sodium acetate buffer to demonstrate how buffers work. Print. (aq) The remaining 75% is wasted as heat. Electrical conductivity measurements at 20C show that 0.98% of the ethylamine has reacted with water. This is in contrast to acids capable of donating more than one proton or hydrogen, which are called polyprotic acids.
