| - C is a mixture of 2 simple inorganic salts. Carry out the following test on C. Record your observation and identify any gases evolved. State the conclusion you draw from the result of each test. (A)Put all C in a test tube,add about 10cm3 of distilled water stir,filter and keep the residue. (B)Put the residue into a test tube,add about 5cm of dilute Hcl acid. Shake to dissolve. (Bi)To about 2cm3 of the solution,add NaoH(aq) in drops and in excesses. (Bii)To another 2cm3 of portion of the solution,add aqeous ammonia in drops then in excesses (Ci)To about 2cm3 portion of the filterate,add few drops of dilute HNo3 acid then 1cm3 of AgNo3 solution. (Cii)To the mixture in ci) above,add aqeous ammonia in excess............................
part B is coming soon; pray so i can remember to post it here.
