0.2143 grams of an unknown organic acid was dissolved in about 50 mL of water in a 250 mL Erlenmeyer flask and titrated against 0.1000 M NAOH solution using bromothymol blue indicator. 30.60 mL of titrant was used to achieve end point. The melting point range of the unknown is 98-102 °C. Ignition test reveals the compound to be aliphatic. Cerric ammonium nitrate test is also positive. Which of the following is the unknown? Hint: Consult Shriner's table.
