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)
To make urine more concentrated, drink less water and consume foods high in salt and protein. This will reduce the amount of water in the body, leading to more concentrated urine.
The solution become more concentrated in sugar.
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 kool-aid will be more diluted; it is not necessary to add very much sugar. The solubility of sugar in water is sufficient also if you use small volumes of water.
It is possible for a time, however, koolaid is more sugar than water so you would dehydrate faster drinking the koolaid, consequently so would any food you consume would dehydrate you. Kool-aid does not give the body essential nutrients so overtime you will suffer the same symptoms of starvation.
No major effects. The salt water and the water join to become a less concentrated salt solution than the salt water but a more concentrated salt solution than the regular water.
The first solution is more concentrated.
Water moves from an area of higher water concentration (dilute solution) to an area of lower water concentration (concentrated solution) in osmosis. This movement occurs across a semi-permeable membrane.
Tricky question. Are you talking about the concentration of salt in the water or the concentration of water in the salt? It is unusual to talk about the concentration of water unless it is dissolved in another solvent like alcohol. Pure water has a constant concentration of 55.6 mol/dm3. Water is more concentrated without salt in it.
Adding detergent to water does not make it more dilute or concentrated. Detergent dissolves in water, so it is considered a solution. The concentration of the detergent in the water depends on the amount of detergent added.
To make a sugar solution more concentrated, you can heat the solution to evaporate some of the water content, thus increasing the ratio of sugar to water. Another way is to keep the solution in an open container to allow water to evaporate naturally, leaving behind a more concentrated sugar solution.
