Answerd plz be detail. Thank You
Suppose an unknown dissolves in water to produce a solution with a pH of 2.4. Which of the following reagents would be useful in obtaining more information about the functional group in the unknown? 3.Suppose a student doing Part C of the experiment. The student gets to the point where all the 6 Much been added. but no pnvipUte of aspirin form. What shinild the student do next' 4. It is suspected that a w.it.r insoJubK solid unknown is an amine Which to the following would tv useful in determining the validity of the suspicion? 5. A water-soluble unknown is found to term a solution with a pH near that of pur.' water which ot tin following functional group* is indicated by that information' 6. Which of the- following would tv useful in helping you identify the functional group indicated m Quistion 5? 7. Which of the following would be formed if the amide shown below was saponified?Explanation / Answer
1) Functional group is
a. 6M HCl : Since pH is very low it means, [H+] is very high which is produced only by HCl; aslo since HCl is only acidic compound.
2) d) more tha one is correct :
depending on the nature of solid weather it is product of wweak acid strong base, or weak base strong acid or other variants different functioal groups can be employed
3)c) stir the liquid : by stirring sometimes reaction starts occuring...as mobility becomes higher of ion.
4)a) 6M HCl solution, since amine is a base and it reacts with a acid.
5) a) CH3COOH since it is a very weak acid.
6) d) More than one answer is correct: using litmus paper or NaOH we can find out the presence of CH3COOH in solution
7) b) Since soap is formed by reaction of ester and Base, which is an neutralisation reaction. Hence as a product salt of ester should be formed.
