<span>The following acids do NOT ionize completely in solution because they are not strong acids are as follows:
a HBr
b HI
c H2SO3
d H3N
e HNO2
f HF

If we compare a cell with an egg there is a major difference between the outer membrane
in case of cell they are bounded by semi permeable membrane
The semi permeable membrane is a selectively permeable membrane which allows the movement of only solvent molecule and not solute molecules through it.
So water can move into or out of the cell through cell membrane by a special physical process known as osmosis.
the water will move from a low concentration gradient to high concentration gradient.
Well , I will say this is a false statement.
This is because compounds which were all made by the same bond have same physical properties but different chemical properties.
Chemical Properties :
How do the subtances react with ( water, acid,alkaline, base , gas like oxygen, etc. )
Physical Properties :
- Solubility of those subtances in (water or organic solvent )
- Electric Conductivity
- Melting or Boiling Point
- Density
- Smell (exp : Ammonia has pungent smell , Esters has fruity smell)
Answer;
They indicate the acidity level. That is, the less pH, the more acidic
Hope it helps :)
