1. Lead nitrate
Molecular Formula: Pb(NO3)2
Relative Molecular Weight: 331.20
Character:
white crystalline, relative density 4.53(20 ),
easily soluble in water, liquid ammonia, light dissolve in ethyl
alcohol, not dissolve in concentrated nitrate acid, solubility 56.5g/100g
water (20). Dry lead
nitrate decompose at 205-223.
Damp lead nitrate decompose at 100,
first become Pb(NO3)2 . PbO, go on
heating, then become PbO. It is strong oxidant, putting together
with organics will lead it burning, noxious. |

Usage: Used as medical astringent;
tanning material for leather-making; dyeing mordant; photograph promoting
agent; flotation for ore; chemical reagents; and also used for making
fireworks, match, and other lead salts.

3. Copper
Sulphate
Molecular Formula: CuSO4.5H2O
Character: Celluloid trimetric crystal or powder in blue ordorlessness,
it will be efflorescent slowly in dry open air and the surface will
become white powder heated to 45,
loss one crystal water; at 102,
loss tow crystal water; at 113,
loss 4 crystal water, become white Copper Sulphate Mono; At 258,
loss all crystal water, become white-green copper sulphate anhydrous
in powder, at 650, it
will decompose to Cupric oxid powder in black and liberate SO3.
It is soluble in water, its liquid react weak acid, slightly soluble
in methanol, insoluble in ethanol anhydrous.

Uage: As a mordant for cotton
and silk; used to produce green and blue pigment; used as insectucude,
bactericide for water, antiseptics for wood, catalyst for tannage, electrocopper,
battery. carving and so on ; used in mining industry and as raw materials
of other chemicals.
In agrochemicstry, it used as pesticide, its liquid mixed with lime
milk in proporting is insecticide for fruit trees and cotton and it
also used to produce other pesticide (contain copper) preventing tanspotting,
smut-fungi of barley & gibberella of wheat; used to produce trace-element
fertilizer and as feed supplement.
