Potassium is a mineral used to help lower blood pressure and moderate electrolytes in the body.
Sodium is basically salt, and large quantities in the body creates high blood pressure. So, it is important to have sufficient potassium, or Vitamin K, and lower sodium or salt.
Potassium is good. Too much for sodium is bad.
The ionisation enthalpy of potassium is lower than that of sodium.
sodium and potassium
Many 'lite salt' products use a potassium salt instead of a sodium salt, and you are correct: your husband should not use these as his potassium levels could rise too high.
potassium chloride
Yes, because chemical properties of sodium and potassium ions are nearly same.
You need 4,700mg of Potassium
I would guess that this is so because of potassium's mass, being much more than, sodium's molar mass per ion. So can sodium iodide be used instead of potassium iodide? Perhaps, but maybe not to the same level effectiveness. Potassium molecules have been known to dissolve better than sodium molecules. One example is Potassium Chloride and Sodium Chloride thanks
magnesium, potassium, and calcium
It is prepared by fusing sodium or potassium carbonate with sand or by heating sodium or potassium hydroxide with sand under pressure.
its ok to use
Yes, for people who have a sodium restricted diet due to high blood pressure, it is possible to substitute potassium chloride.
same as other ions. Note that in your body potassium salts within cells balances the osmotic pressure of sodium salts in the extracellular fluid.
