Transparent soaps are made by cold process
Organic pigments are used as colouring materials in the soap manufacture
Both laundry as well as toilet soaps are manufactured by hot process
Colourless rosin is used in the manufacture of laundry soaps
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
