About 90% of nitric acid is manufactured by Ostwald's process
It is a strong mono basic acid which reacts with almost all the metals except noble metals
Yellow color of impure nitric acid is because of dissolved oxides of nitrogen (mainly NO2)
Arc process of nitric acid manufacture is economical as compared to Ostwald's process

Glycerol
Soap from lye
Glycerine from lye
The metallic soap
The unsaponified fat from soap
It is very corrosive at elevated temperature
Its viscosity is not reduced on further heating (hence pressure drop on pumping it, cannot be further reduced)
It decomposes on further increasing the temperature

Conversion of SO2 to SO3 in Monsanto-4 pass converter is about 98%
The chemical formula of oleum is H2S2O7, which is formed by saturating sulphuric acid with sulphur trioxide
Vitriol oil is nothing but technical sulphuric acid
Decomposition of sulphuric acid on heating does not start before its boiling

Hard glass which is used for making laboratory glass wares is a mixture of sodium borosilicate and aluminium borosilicate
Glass is decolorized during its manufacture by adding antimony oxide, manganese dioxide or arsenic oxide
Ordinary glass is represented chemically by Na2O . CaO . 6SiO2
Red color is imparted to glass by addition of arsenic oxide
