NALYSIS TRIAL QUESTIONS
1. E is a simple salt. Carry out the following exercises on E. Record your observation and identify any gas(es) evolved. State the conclusion you draw from the results of each test.
(a) Dissolve all of E in about 10 cm3 of distilled water.
(b) Divide solution E into three portions.
(i) To the first portion, add NaOH(aq) in drops, then in excess.
(ii) Warm the resulting solution from (bi).
(iii) To the third portion, add dilute HNO3 followed by few drops of AgNO3(aq)
and then excess NH3(aq).
ASSUME E to be NH4Cl
2. F is a simple salt. Carry out the following exercises on F. Record your observation and identify any gas(es) evolved. State the conclusion you draw from the results of each test.
(a) Dissolve all of F in about 10 cm3 of distilled water and shake. Divide the solution into
three portions.
(b) To the first portion, add NaOH(aq) in drops, then in excess.
(c) To the second portion, add few drops of BaCl2(aq) followed by excess dilute HCl.
(d) To the third portion, add dilute NH3 in drops, then in excess.
ASSUME F to be CuSO
