Tonicity refers to the relative concentration of solute particles inside a cell, with respect to the concentration outside the cell. Osmolarity refers to the movement of water from the inside to the outside of a cell, and vice versa
Molarity or Molality
Isotonic
Tonicity is measure of the effective of osmotic pressure. Osmosis is the minimum pressure which needs to be applied to a solution.
When giving an iso-osmotic transfusion you do not want a solution that has the same salt concentration as blood but rather has the same tonicity(osmotic pressure). This is crucial because if the tonicity of blood changes it can cause cells to burst or shrink depending on the direction of change of the tonicity. So in the case of iso-osmotic transfusion you would give a 0.9% solution of NaCl. To prove that this is iso-osmotic to blood(close to 300 mosm) look below: 0.9% means 0.9gNaCl/100ml= 9gNaCl/L=(9gNaCl/L)*(1mole/58.5g)= 0.153moles/L Osmolarity = molarity*(number of ions)=0.153Molar*2= 0.306 osm = 306 mosm Hope that helps
What is the tonicity of you blood
Tonicity refers to the measure of the effective osmotic pressure gradient between two solutions. The higher the difference in the tonicity between the two solutions, the more osmosis transpires.

nothin much happens
TONICITY
Tonicity is a measure of the effective osmotic pressure gradient; the water potential of two solutions separated by a semipermeable cell membrane. In other words, tonicity is the relative concentration of solutes dissolved in solution which determine the direction and extent of diffusion. It is commonly used when describing the response of cells immersed in an external solution.

Yes, if you contract the right muscles.

The three type are hypertonic, isotonic, and hypotonic. Hypertonic is when the tonicity of the cell is lower than that of the surrounding liquid, isotonic is when the tonicity of the cell is equal to that of the surrounding liquid, and hypotonic is when the tonicity of the cell is greater than that of the surrounding liquid.
