What percent of fresh water is good water?
30% or less of our water is a fresh water
Do water dissolve more substance than any other liquid?
No, not all substances dissolve in water. Substances that are nonpolar, meaning that they don't have a dipole moment, will not be able to dissolve in water because water is a polar solvent. Only polar solutes will dissolve in polar solvents. Oil is an example of such a substance that is nonpolar and does not dissolve in water. There are also ionic compounds that are insoluble in water, such as silver bromide (AgBr), potassium sulfide (K2S), and lead(II) sulfate (PbSO4).
Does tap water boil faster than sugar water and salt water because of less surface tension?
Because salt water already has NaCl(salt) dissolved into it. Water molecules can only break down so much, and so fast to combine with other molecules. When you dissolve sugar in tap water, there are not many different substances dissolved into it yet, so it's easier for the sugar cube to dissolve.
Why does it take alka- seltzer longer to dissolve in cold water?
Beause cold water is less dissovlable
What water has more salinity than fresh water but less than sea water?
Brackish Water.
Does sugar dissolve faster in salt or fresh water?
I would think it would dissolve faster in fresh water, as the fresh water doesn't have anything dissolved in it yet whereas the salt water has dissolved salts and so less room for the sugar molecules. A. yes; sugar does dissolve faster than salt does, in fresh water.
Why iodine is more soluble in cl but less soluble in water?
Iodine is not soluble in water because iodine is nonpolar and water is polar. According to the "Like dissolve like" expression, nonpolar substances are soluble with nonpolar substances and polar substances are soluble with polar substances, but nonpolar substances are not soluble with polar substances.
What substances can water dissolve?
the substance can disslove in water (h2o) are most POWDER. Additional answer A powder is no more or no less able to dissolve in water than if that substance were NOT a powder. Powdering something does not help to make it soluble, though it might make it dissolve more quickly if it's able to dissolve at all. Some substances that dissolve to some extent are salt, sugar, calciul sulphate, copper chloride - millions of things
Hydrophobic substances such as vegetable oil are?
Nonpolar substances that repel water molecules.
Why is Limestone is used to purify sugar?
To make it less acidic and to dissolve the impure substances.
Why is water an excellent solvent for most ionic and polar covalent compounds but not for non polar compound?
Not all ionic salts dissolve in water, just most of them. Anyways, most molecular substances don't dissolve in water because they are more stable not dissolved. This is partly due to the fact that covalent bonds are stronger than ionic bonds. An example of a non-polar substances that can dissolve in water is diatomic fluorine, which when bubbled into water will dissolve.
What percent of fresh water is good water?
30% or less of our water is a fresh water
Why does salt dissolve quicker then other substances?
I think its because its less dense but im not sure
4 Do all substances dissolve in water to form a solution?
No, not all substances dissolve in water to form a solution. Cooking oil is a good example, if you mix with water it will remain separated and float to the top - it is less dense. Water would have to break almost all its intermolecular hydrogen bonds in order to accomodate it (which of course it doesn't), and therefore it does not form a solution. Solubility depends on what you are adding to the water. If you are adding an alcohol for example, it has O-H bonds which will readily form hydrogen bonds with the water molecules, and so dissolves. Water is also a polar solvent, so ionic substances will also tend to dissolve in it. Hope that helps!
Why marine fish die when placed in fresh water?
because there is a difference in salinity which means less salt there is alot less in fresh water
If Earths climate became colder how might fresh water supply be affected?
there would be less evaporation and so less rainfall and as a result less fresh water
Density of an object is less than density of water?
It is for some substances and not for other substances.
