Which is more reactive sodium or lithium or potassium?
K; Potassium
Is potassium more or less active than sodium?
Potassium is more reactive than sodium
Which is more reactive francium sodium or potassium?
Fr; Francium
Why does potassium react more in water than sodium?
Potassium has a lower electronegativity value than sodium, meaning (among other things) that it gives up an electron more readily, and therefore displaces hydrogen more readily, than sodium does.
Why is potassium iodide used in iodometric titrations instead of sodium iodide?
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
Are Excitable cells like neurons are more permeable to sodium than to potassium?
More permeable to K than Na
When a nerve is activated by a threshold stimulus the membrane becomes more permeable to?
Potassium and Sodium
Where is potassium reabsorbed and secreted?
The absorption of sodium affects the secretion of potassium by making it more difficult for the potassium to be permeable by blocking the areas it travels through.
Why is The plasma membrane is much more permeable to K than to Na?
Even when both those atoms are encapsulated with water, potassium is smaller than sodium.
Which is more reactive sodium or lithium or potassium?
K; Potassium
Is potassium more or less active than sodium?
Potassium is more reactive than sodium
What is the effect of decreasing the number of sodium potassium pumps?
When number of sodium-potassium pump decreased, transport of Na takes little more time. Less number of sodium-potassium more time for transport
Ions used to establish a resting potential?
Potassium and sodium determine the a cell's resting membrane potential. The equilibrium potential (the voltage where no ion would flow) for sodium is about +60 mV while that for potassium is usually around -80 mV, but because the resting cell membrane is approximately 75 times more permeable to potassium than to sodium, the resting potential is closer the the equilibrium potential of potassium. This is because potassium leak channels are always open while sodium come in through voltage gated or ligand gated channels.
Which is more reactive than sodium?
Potassium
Why is the plasma membrane more permeable to potassium ions than sodium ions?
Some substances, including sodium and potassium, use a process called active transport to permeate cell walls. Active transport is controlled by other body systems. It limits the quantity of these substances passing through the plasma membrane to match the needs of the body.
Is diclofenac potassium is more powerful than diclofenac sodium?
Case to case basis. In my case diclofenac potassium is more powerful than diclofenac sodium.
Which has more mass a mole of potassium or a mole of sodium?
A mole of potassium. Sodium weighs 22.990 g/mol while potassium weighs 39.068 g/mol.
