Eosin requirement in tallow soap is about 40-50% which fastens the lather formation, softens the hard soaps and increases its cleansing action
Soap powder is prepared by mixing soap with hydrated sodium carbonate
Detergents differ from soaps in their action in hard water
Tarnish inhibitor (e.g., Benzotriazole) is added in soap to facilitate the removal of stains due to tea, blood etc

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
