==Purpose==<br />
To use the concentration of a known base to determine the concentration of an unknown acid<br />
<br />
==Directions==<br />
Titrate to endpoint a ''sodium hydroxide solution'' with a ''acetic acid solution'' of an unknown concentration. Use phenolphthalein as an indicator. Start with 10mL of acid.<br />
<br />
==Results==<br />
*Using Acid "B" at .1012M concentration<br />
*Filled up both burettes to 0mL<br />
<br />
'''Titrated with 10.20mL of Acid "B" amd 10.11mL Base'''<br />
<br />
*'''V<sub>A</sub>*C<sub>A</sub>=V<sub>B</sub>*C<sub>B</sub>'''<br />
*10.20ml Acid * ?M Acid = 10.11mL base * .1012M Base<br />
*10.20mL * ?M Acid = 1.023132 mlM base<br />
