Water,
More concentrated to less concentrated
Add More Salt to make it more concentrated and add more wtaer to make it less concentrated
No. Water tends to diffuse from a region where it (water) is more concentrated to a region where it (water) is less concentrated. The other way of thinking about this is that water diffuses from an area of high solute concentration to an area of low solute concentration.
The diffusion of substances across a membrane is called passive transport. Molecules move from where the substance is more concentrated to where it is less concentrated.
Assuming you mean a solution of salt, you would add WATER.
true
diluted acid is less concentrated i.e. it is mixed with water and a less harmful(like sulphuric acid.) whereas concentrated acid is in its original form...
Osmosis
No, it goes from HIGH concentration, to LOW concentration
The clearer your urine is, the less concentrated it is. If it is clear, it is almost all water, if it is pale there is less water.
ADH causes an increase in water reabsorption in the kidneys. Thus, by absorbing more water, the urine becomes MORE concentrated (more compounds in less water = more concentrated)
