Used as dyes, pigments, odor agents,
oxidizing/reducing agents, food additive, blood
testing in clinical laboratories and solvents that
become part of formulations or mixtures
...

Ethanoate ions form a red complex with
iron (III) ions
...
Preparation:
Methanol and carbon monoxide, both formed
via synthesis gas are reacted together in the liquid
phase, with some water to keep the catalyst in
solution, at moderate temperatures of about 450 K
and a pressure of 30 atm
...
A catalyst,

usually a metal complex, is needed for the
carbonylation (step 2)
...
Add
40 ml of water, then add phenolphthalein TS and
titrate with 1 N sodium hydroxide
...
05 mg of
C2H4O2
...
When heated above 440 °C (824 °F),
acetic acid decomposes to produce carbon
dioxide and methane, or to produce ketene and
water:
CH3COOH → CH4 + CO2

Barium Hydroxide Lime
Synonyms:
- Bariumhydroxide
- Bardium dihydroxide

Ba(OH)2

Test for Identity:
Method A
- Place a granule of it in a moistened litmus
paper; the paper turns blue immediately
...

Lab
...
After mixing
the whole mass very thoroughly in a
mortar is placed in the crucible, pressed
down firmly, and covered with a layer of
charcoal at least 1-2 centimeters deep
...
After the crucible
has cooled, the top layer of charcoal is
removed barium oxide is placed in
the porcelain dish, and very cautiously
treated with 400 ml of water
...

4) The residue is rinsed in the dish with 75 ml
more of boiling water and poured this upon

Used for titration of weak acids, additive for
lubricants and greases, for sugar fabrication,
manufacturing of soap, fat saponification and
chemical synthesis of other barium compounds and
organic compounds
...
The filtrate is cooled slowly to
room temperature and then to 0° C in the
ice-water bath
...
During
drying and storing, barium hydroxide
should
be
protected
from
atmospheric carbon dioxide
...

Ba(OH)2  BaO + H2O

Boric Acid
Synonyms:
- Boric Acid NF XV
- Boracic Acid
- Hydrogen Borate
- Orthoboric Acid

H3BO3

Test for Identity:
- Use a clean wire loop made out of
platinum or nickelchromium (nichrome)
wire, dip the loop into Boric Acid, and the
place it into the hottest portion of a flame
...

Lab
...
Solution
produced was heated
...
Furthermore, it is used as a
buffer in ophthalmic solutions
...

1) The solution in the beaker was left until the
temperature of the solution was falling
down to room temperature
...

2) The crystal was filtered off by using
suction pump, suction funnel, and filter
papers (2 pieces which the weight was
already measured)
...

3) The product yield from the filtration was
taken out from suction funnel together with
the filter papers
...
The watch glass with the
products on it was weight with analytical
balance
...
Discharge the pink color by the
addition of 50ml of glycerine, neutralized to

phenolphthalein TS, and continue titration until pink
color reapers
...
83 mg of Boric Acid

Selenious Acid
Synonyms:
- Selenous Acid
- Selenium Red
- Selenium Mixture

H2O3Se
H2SeO3

Test for Identity:
Method A
- Dissolve about 50 mg in 5mL of water, add
about 100 mg of sodium bicarbonate, and
mix: gas bubbles develop
...
1 N
hydrochloric acid, and add about 50 mg of
stannous chloride: a curdy tan-orange
precipitate is formed
...
Preparation:
1) 113 ml of concentrated nitric acid nitric are
gently heated in the flask until the acid
almost boils
...
The addition is
continued until all 39 grams of selenium
have been added
...


Used as antiviral agents and as antioxidants
...

The flask is cooled, the solution is filtered,
and the filtrate is left to stand in a
previously weighed beaker until the
solution has evaporated to dryness
...

3) The crude selenous acid is dissolved in
one-fifth its weight of boiling water, cooled
to room temperature, and the
crystallization is initiated by seeding with
small crystal or by rubbing the solution
with a glass rod
...

Se + 2HNO3 H2SeO3 + NO2 + NO
Assay:
Transfer about 100 mg of selenious acid,
accurately weighed, to a suitable glass-stoppered
flask, and dissolve in 50 ml of water
...
Add 50 ml of water and 3ml of
starch TS, and titrate with 0
...
1 N iodine VS to a blue endpoint
...
1 N iodine from the volume of 0
...
1 N
sodium thiosulfate equivalent to selenious acid
...
1 sodium thiosulfate is equivalent to

...
, decomposition begins to occur with
formation of selenium dioxide, oxygen and water
...

BaCl2 + H2SO4  BaSO4 + 2HCl
Lab
...

2) The gases are mixed with more air then
cleaned by electrostatic precipitation to
remove any particulate matter
...
3-202
...


Used as a strong diprotic acid which can be utilized
to form salts of basic organic drug molecules
...


4) Sulfur trioxide is dissolved in 98% (18M)
sulfuric acid, H2SO4, to produce disulfuric
acid or pyrosulfuric acid, also known as
fuming sulfuric acid or oleum, H2S2O7
...

5) Water is added to the disulfuric acid to
produce sulfuric acid
...
Dilute with about 25 ml of
water, cool, add methyl orange TS, and nitrate with
1 N sodium hydroxide VS
...
09 mg of H2SO4

Test for Identity:
Used for official preparations, tests and assays as
1) Add a few drops to white anhydrous well as sterile dosage forms, excluding parenteral
copper(II) sulphate
...

blue
...

2)

Dip in a piece of dry blue cobalt chloride
paper
...
Pink
hydrated cobalt ion is formed
...
Preparation:
1) Fill one jar with ordinary tap water
...
This lid must have an opening
to insert the glass tube in it
...

2) This second jar should be covered with the
lid having two holes in it
...

3)

Insert a small capillary tube into empty
hole of lid of second jar to make it act like
a chimney for steam
...
Ice will act
as a condenser for incoming steam
...


4) Now, boil the water of first jar
...
It will get

condensed into pure distilled water
...

Decomposition:
3000° C, more than half of the water molecules
are decomposed to hydrogen and oxygen
components
