Water-Soluble Inorganic
Materials
By Christine Lee, Adriana Cho, Lindsey Harris, and
Haley Miller
APES Period 1
Description 😄
★ acids, salts, and
toxic metals
★ toxic in large
amounts
★ ex. arsenic,
chromium salts,
aluminium,
mercury, and lead
Source of Pollution 😈
★ main source is industry
★ point sources: easily
identifiable
★ pesticides and fertilizers
★ ex. chromium salts used
in air-conditioning
Negative Effects
🙈
★ Large quantities
make water unfit for
drinking
★ toxic to aquatic life
and plants (crops)
★ Causes Acid Rain
e.g. Nitric Acid +
H2S04(sulfuric acid)
★ Has poor
Biodegradability
Remediation 😎
Precipitation:
★ For water containing
heavy metals, it’s
common (but depends
on the concentration)
★ However, it creates
sludge that requires
further treatment

Remediation 😒
Ion Exchange:
★ Uses special resins to remove charged, inorganic
contaminants from water
○ cation resins: exchange cations like calcium,
magnesium, and radium
○ anion resins: remove anions like nitrate, arsenate,
arsenite, or chromate

Remediation 😡
Adsorption:
★ where a solid (carbon) is used
for removing a soluble
substance from the water
★ Active carbon comes in two
variations: Powder Activated
Carbon (PAC) and Granular
Activated Carbon (GAC). The
GAC version is mostly used in
water treatment.
