The present study focusses on the conspicuous properties of the temporal and spatial K‐dV solitary waves obtainable by the use of different stretching co‐ordinates. Singularities are observed in solitary waves which are due to the presence of negative ions and multiple electron‐temperatures in the plasmas. It is discussed how those situations are tackled by the derivation of modified K‐dV equations to describe the evolution of propagating solitons. Moreover, the soliton profiles admit the interactions of negative ions and multiple electron‐temperatures, which are playing the role of creating the steepness in soliton profiles. Simultaneously more solitary waves follow therein resembling the evolution of experimentally observed soliton characteristics and finally indicating the possible interest to put forth for experimental plasma investigations.
