The evaporation is slower from impure solutions.
No, the concentration of salt remains the same even if water evaporates. However, the amount of water decreases, causing the remaining water to have a higher concentration of salt.
Not at all because when the water evaporates the salt remains unchanged
Yes, it does. When the water evaporates, it can not take the salt with it, so if you left a glass of salt water out, when it is evaporated the salt will be on the glass.
When salt water evaporates, the water molecules dissipate into the air, leaving behind the salt ions. These ions will eventually form salt crystals as the remaining water evaporates completely.
Water mixed with salt does not affect the taste,bt it also depend on the amount of water mixed with the salt and the quantity of salt mixed with the water
Two graduated beakers. Water and salt. Put a known amount of plain water in one and the same amount of salt water in the second beaker. Then observe which one evaporates faster.
They all evaporate at the same rate. The sugar and salt are in solution with the water. The sugar and salt will remain in the container after the water has evaporated. It will not affect the rate at which the water evaporates. I think you are wrong.Based on an experiment, sugar water evaporates the fastest followed by salt water as the more molecular weight the faster it evaporates.Sugar has more molecular weight than salt.
Salt water evaporates through the same process as regular water. As the heat energy from the sun causes the water molecules at the surface to gain enough energy to escape into the air as water vapor, the salt in the water is left behind. So, the salt water evaporates, leaving behind the salt.
If the water was pure and had no salt already mixed in it then the same 20 grams of salt would be left, as salt doesn't evaporates on the temperature at which water does evaporates.
Yes, temperature can affect the amount of salt that dissolves in water. Generally, as temperature increases, the solubility of salt also increases, meaning that more salt can dissolve in water at higher temperatures.
This is salt water.
After water evaporation solid salt remain as a residue.
