First, take a clean wire loop of Platinum or nickel-
chromium . They may be cleaned by dipping in hydrochloric
or nitric acid, followed by rinsing with distilled or
deionized water.
Test the cleanliness of the loop by inserting it into a
bunsen burner flame. If a burst of color is produced, the
loop was not sufficiently clean.
Ideally, a separate loop is used for each sample to be
tested, but a loop may be carefully cleaned between tests.
The clean loop is dipped in either a powder or solution of
an ionic (metal) salt. The loop with sample is placed in
the clear or blue part of the flame and the resulting color
is observed.
In this way Flame test is done.

2. Two grams of Benzoic acid are dissolved in 200 ml of water and extracted with 200 ml of diethyl ether. The distribution coefficient of benzoic acid is 100, and its dissociation constant is 6.5 10-5. Calculate the distribution ratio (D) of benzoic acid at pH 2, 5, and 6. 3. Calculate D at pH 2 to 10 (1 unit apart) in the above problem, and plot D versus pH.
