What happens to the density of distilled water when you add salt to it?
When you add table salt (sodium chloride, NaCl) to water, the salt dissolves into ions, Na+ and Cl-. The volume increases by a small factor, but the mass increases by a bigger factor. There are two reasons. One is simply that the NaCl is much denser than water to begin with, mainly because its ions have more mass than the oxygen and hydrogen atoms in the water molecules. Also, the ions bind nicely with the water molecules, so that the volume of the saltwater isn't as big as the water volume plus the salt volume.
What makes dry ice and cola react?
Dry ice is solid carbon dioxide (CO2); cola is a super-saturated solution of carbon dioxide (and other things). If you add a crystal of salt to a supersaturated salt solution, the extra salt dissolved in the water will start crystallizing around that "seed" crystal you added and come out of solution. Relatedly, when you add solid/gaseous pure CO2 to a supersaturated CO2 solution, the extra dissolved CO2 will start coming out of solution, prompted by the addition of pure CO2.
Does salt affect how fast ice melt in a cup of water?
Salt affects how fast ice melts in a cup of water. When you add salt, the melting process will be faster but it will only affect the part of the ice cube that comes into contact with salt.
How does fresh water become salt water?
Water is already water so when water goes with water it becomes water then you add salt and water and it becomes salt water so you take your salt water and take your water in the water and mix the water in the water with the salt water it becomes the water in the water with salt water
What are facts about separating salt from pepper?
Salt can dissolve while pepper cannot. So one way to separate salt and pepper would be to add water until all the salt dissolved and pouring the liquid out. Then, let the salt water solution evaporate, leaving salt behind! =D
If pure water has a density of one gram per milliliter why does an egg sink in it but float in salt water?
That indicates that the average density of an egg is greater than the density of pure water but less than that of salt water. Salt water has more density the regular/pure water and the more salt you add the more it floats.
How many spoonfuls of salt did you add to the cold water until it cannot dissolve anymore?
Depends on how much water(how pure it is also) and how dense the type of salt is.
Is saltwater a substance?
no Its a solution. If you mix salt in water, the salt dissolves. It is then a solution. That is not a mixture. It may well be a pure substance. If it is pure salt water it is pure. But if you add some soap it is then pure soapy salt water. What does pure mean? Pure is not a scientific term, so its meaning is debatable. Pure orange juice for instance, has no real meaning as orange juice contains many different things, so how is it pure? In fact if by the previous persons definition of pure, [wood is not but glass is] is incorrect as glass is a compound of several things as is wood. Pure water is a compound of hydrogen and oxygen. So is that pure ,or not?
Why is salt called a pure substance and salt solution to be considered to be a mixture?
Dry salt - is a compound of sodium and chlorine atoms. If you add it to water, it then mixes with the atoms of oxygen and hydrogen.
Can you make salt water with salt and water?
Yes, you make salt water with salt and water.
What is the affect of the boiling point when you add salt in pure water?
It raises the boiling point of water and it can make it taste funny and yooh smell
Which water evaporate fast salt water or pure water?
pure waterDiscussionDissolving something in water which does not evaporate easily will make the mixed solution less likely to evaporate than pure water. The more stuff you add to it, the less likely it will evaporate.Adding salt to water makes ions in solution and these ions reduce the vapor pressure of the solution compared to pure water. The lower the vapor pressure of a liquid or solution, the slower it will evaporate. This effect is also related to boiling point elevation and freezing point depression.
What is the temperature if you put salt in water?
Adding salt does not effect the temperature.Answer:Adding salt does not change the temperature at the time you add the salt, but it raises the temperature at which the water will boil
Steps to see if adding salt to water change the temperature at which it boils?
To test if adding salt to water increases the boiling point of the water, do the following: boil a sample of pure water until it boils. Measure the temperature at which the pure water boils. Take another sample of pure water and add salt to it, then boil this sample under the same conditions. Measure the temperature at which the salt water boils. If the latter temperature is higher, salt does increase the boiling point of water.
Does pure water conduct electricity if not what can you do to make it conducting answer in detail.?
Pure water is a poor conductor of electricity because it lacks ions for the current to flow through. To make water conductive, you can add salt or another electrolyte to it. The salt dissociates into ions in the water, allowing it to conduct electricity.
What is happening when you add salt to water?
Depending on how much salt you add to the water and how warm the water is... the salt will disolve
How do you put liquid back in sea salt that is dried up?
Just add water.
