Kraft temperature is the temperature :

Adsorption of a gas follows Freundlich adsorption isotherm. If x is the mass of the gas adsorbed on mass
m of the adsorbent, the correct plot of $${x \over m}$$ versus p is :

Identify the correct molecular picture showing that happens at the critical micellar concentration (CMC) of an aqueous solution of a surfactant ( ◍ polar head; ∼ non-polar tail; ● water).

A sample of red ink (a colloidal suspension) is prepared by mixing eosin dye, egg white, HCHO and water. The component which ensures stability of the ink sample is :
