Why would potassium permanganate have a greater rate of diffusion down a agar tube than methylene blue?

Methylene Blue has a higher molecular weight than the compound potassium permanganate. Potassium permanganate has smaller, lighter molecules which diffuse faster than methylene blue's larger, heavier molecules.

Which is greater the second ionization energy of potassium or that of calcium?
potassium is greater in the second ionization energy.
Why is sodium nitrate more soluble than potassium nitrate?
Yes. Because hydration energy of Na+ is greater than K+. More the hydration energy greater is solubility. A compound is soluble if hydration energy is greater than lattice energy.
What is the PH value of potassium sulphate?
The pKa of HSO4- (the second pKa of H2SO4) is 1.92. The Ka is thus 0.0120
What are the chemical components of vesicular basalt?
Vesicular basalts are usually felsic, with a SiO2 content greater than 69%. They may also contain sodium, aluminum, potassium, oxygen, hydrogen, and iron.
What is the dencity of feldspar?
It varies from 2.52 - 2.74 grams/cc (Orthoclas=2.52 Anorthite=2.74) The density varies to heavier with greater amounts of Sodium or Calcium and lighter for Potassium Feldspar (Orthoclase)
What is the movement of molecules from greater to lower?
Diffusion.
What controls the rate of diffusion?
The rate of diffusion is directly related to the concentration of gradient. For example, the greater the amount between the concentration of the areas, the greater the greater to difference in diffusion.
Which is greater the second ionization energy of potassium or that of calcium?
potassium is greater in the second ionization energy.
Which has a greater atomic mass potassium or francium?
potassium
How does kinetic energy affect diffusion rate?
The greater the collision rate, the greater the diffusion rate. As the molecules of the substance that is diffusing are more concentrated, the molecules collide more. As they diffuse and spread apart, there are less collisions and diffusion slows down.
What is true statements about diffusion?
The greater the concentration gradient, the faster the rate of diffusion.
What is A true statement about diffusion?
The greater the concentration gradient, the faster the rate of diffusion.
What influences diffusion of ions across the membrane?
distance involved =diffusion at short distances occurs at a greater rate than diffusion at long distances area involved= diffusion over short distance occurs at a greater rate than diffusion over long distances Barriers=thicker barriers slow down rates of diffusion
What is the movement of molecules from a greater to lesser area?
diffusion
Diffusion is defined as a movement of molecules?
Is Diffusion the movement of molecules from a greater to a lesser concentration.
Does potassium have greater electronegative than bromine?
No.
Is the movement of ions from an area of greater concentration to one of lesser concentration an example of osmosis?
The movement of ions/molecules from an area of greater concentration to an area of lesser concentration is called diffusion.Osmosis is a type of diffusion, which refers specifically to the movement of the solvent (usually water).
