WebJan 29, 2016 · Activity depends on temperature, pressure and composition of the mixture, among other things. For gases, the activity is ... (moles solute/kg solvent) for dilute solutions. Often molality is approximated with molarity (moles solute/Liter solution). ... SO 4 2-, OH-, and H + ions will not affect each other greatly, thus the activity of the ions ... WebFeb 24, 2024 · Hence, molality does not affect the temperature change. Why does dissolved oxygen decrease with temperature? The temperature and salinity of water influence how much oxygen it can hold. Warm water holds less dissolved oxygen than cold water because the molecules are moving faster than in cold water and thereby allow …
