The properties of ion-acoustic and electron-acoustic solitons are studied for fluid models describing three-component and four-component space plasmas. Each plasma model is composed of one or two (different temperatures but same mass) ion species and one or two (different temperatures) electron species. We use a reductive perturbation method to derive Korteweg- deVries equations that describe small-amplitude solitons for each model. The results are shown to be in good agreement with arbitrary amplitude soliton results available in the literature. A comparison of the results for the different models will provide insight into how polarity changes in the observed soliton structures are related to the plasma composition.
