澳大利亚南澳大学化学论文代写:摩尔钾离子

此外,有时需要考虑多种类型的溶质。如果您的半透膜具有2摩尔Na +离子和2摩尔Cl-离子,另一侧有2摩尔K +离子和2摩尔Cl-离子,则确定张力可能会造成混淆。如果您认为每侧有4摩尔离子,则隔板的每一侧相对于另一侧是等渗的。然而,钠离子侧相对于该类离子是高渗的(另一侧对于钠离子是低渗的)。具有钾离子的一侧相对于钾是高渗的(并且氯化钠溶液相对于钾是低渗的)。您如何看待离子穿过膜?会有运动吗?您期望发生的是钠和钾离子穿过膜直到达到平衡,分区的两侧含有1摩尔钠离子,1摩尔钾离子和2摩尔氯离子。得到它了?水在半透膜上移动。请记住,水会移动以均衡溶质颗粒的浓度。如果膜两侧的溶液是等渗的,水就会自由前后移动。水从膜的低渗(浓度较低)侧移动到高渗(浓度较低)侧。流动的方向持续直到溶液是等渗的。 澳大利亚南澳大学化学论文代写:摩尔钾离子 In addition, there are times when multiple types of solutes need to be considered. If your semi-permeable membrane has 2 moles of Na + ions and 2 moles of Cl-ion and 2 moles of K + ions and 2 moles of Cl- ions on the other side, determining the tension may cause confusion. If you think there are 4 moles of ions on each side, each side of the separator is isotonic with respect to the other side. However, the sodium ion side is hypertonic with respect to this type of ion (the other side is hypotonic for sodium ions). The side with potassium ions is hypertonic with respect to potassium (and the sodium chloride solution is hypotonic relative to potassium). How do you think about ions passing through the membrane? Will there be exercise? What you expect is that sodium and potassium ions pass through the membrane until equilibrium is reached, with 1 mole of sodium, 1...
