A short summary of this paper. The result for a cation species at low electrolyte molality is a decrease of $$\mu_+$$ compared to the cation at same molality in the absence of ion–ion interactions, meaning that the single-ion activity coefficient $$\g_+$$ becomes less than $$1$$ as the electrolyte molality is increased beyond the ideal-dilute range. VOTE NOW! The ray of light traveling from the upper layers gets deviated away from normal and suffers total internal reflection and the distant object appears to be inverted and to the observer pool of water appears at a distant place and this phenomenon is called mirage. And why, in the English of Ireland, are we so fond of saying 'any ould yoke'? Most phosphoric fertilizers are obtained by the treatment of calcium phosphate with H2SO4and phosphoric fertilizers.
