# What are five examples of buffer solutions?

Mar 28, 2018

You want only FIVE, why not 55?

#### Explanation:

A buffer solution is composed of a weak acid, and its conjugate base in appreciable concentrations...and so five examples are...

$\left(i\right)$ $\text{Acetic acid/sodium acetate}$

$\left(i i\right)$ $\text{Ammonium chloride/ammonia}$

$\left(i i i\right)$ $\text{Bicarbonate/carbon dioxide (carbonic acid)}$

$\left(i v\right)$ $\text{dihydrogen phosphate/biphosphate}$

$\left(v\right)$ $\text{Citric acid/citrate}$
