What else can I help you with?
Is potassium more or less active than sodium?
Potassium is more reactive than sodium. This is because potassium is lower in the alkali metal group and has one more electron, making it more likely to lose that electron and react with other elements.
What is the difference in sodium hydroxide and potassium hydroxide?
The difference is that sodium hydroxide contains the sodium ion (Na+) while potassium hydroxide contains the potassium ion (K+). Sodium and potassium are two different elements, though they have different properties.
Sodium reacts with water more vigorously than potassium. why?
Sodium reacts more vigorously with water than potassium because sodium has a lower ionization energy and is more reactive. When sodium comes into contact with water, it forms sodium hydroxide and releases hydrogen gas, resulting in a more rapid and vigorous reaction compared to potassium.
Why sodium has more density than potassium?
Sodium has a higher density than potassium because it has a greater atomic mass per atom. This means that sodium atoms are heavier than potassium atoms, leading to a higher density of sodium compared to potassium.
Does sodium have the larger first ionization energy than potassium?
No, potassium has a larger first ionization energy than sodium. Potassium has an extra electron in its valence shell compared to sodium, making it more difficult to remove an electron from a potassium atom compared to a sodium atom.
Are Excitable cells like neurons are more permeable to sodium than to potassium?
Yes, excitable cells like neurons are more permeable to sodium ions than potassium ions. This selective permeability is due to the presence of more sodium channels compared to potassium channels in the cell membrane, allowing sodium to flow into the cell more readily during an action potential.
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 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.
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.
What metal can displace sodium?
Potassium can displace sodium, as potassium is more reactive than sodium. When potassium is added to a solution containing sodium ions, a displacement reaction can occur where potassium replaces sodium in the chemical compound.
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.
Is potassium more or less active than sodium?
Potassium is more reactive than sodium. This is because potassium is lower in the alkali metal group and has one more electron, making it more likely to lose that electron and react with other elements.
