Yоu аre prоvided with а sаmple cоntaining two compounds. The sample is a solid. The two compounds possess different chemical properties. Compound A is an organic acid. Compound B is a neither an acid nor a base; it is neutral. Both compounds are highly soluble in diethyl ether, so you dissolve 1.0 gram of the mixture in 50mL of ether. You wash the ether solution with 25mL of 5% NaHCO3 (sodium bicarbonate) a total of three times. You combine the aqueous washings in a 125mL Erlenmeyer flask, then cool the flask in an ice bath. You slowly add 6M HCl (hydrochloric acid), monitoring the pH as you go, until you achieve a pH of 2, at which point a white mass has formed in the aqueous solution. You pour the aqueous solution into a Buchner funnel, wash the collected solid with cold deionized water, then dry the solid.What is the solid you have just isolated?
