| Özet: | Заглавие с экрана In this work the experimental determination of the enthalpy of formation of rubidium and cesium tetrafluorobromates is carried out. The investigation of the thermodynamic parameters is based on the need to replenish the missing literature data. The synthesis of alkali metal tetrafluorobromates was done by the so-called liquid phase method. The experimental determination of the values of the thermal effects of the reactions of rubidium and cesium chlorides with bromine trifluoride was conducted by thermal calorimetry. In conclusion, the sets of the enthalpies of alkali metal tetrafluorobromates were analyzed and the analysis showed that the values of the enthalpies are gradually increasing from Na to Cs compounds. |
