What kinds of substance dissolves in water?

Answer 1

Powders like sugar, salt, baking soda, etc.

Answer 2

Many substances dissolve or even react with water. Polar substances dissolve very readily in many cases. Salts usually dissolve quite easily. Note NOT ALL polar substance dissolve in water completely. Barium sulfate is polar and is a a salt but is very sparingly soluble. There are many other such examples.

Water is a polar solvent, meaning that the water molecule has positive and negative poles. As a result, it is a very effective solvent for other polar substances, particularly salts. Since water is also very abundant, it is the most commonly used solvent, here on Earth. When you may want to use water to dissolve a non-polar compound, such as an oil, that normally doesn't dissolve in water, you can make it soluble by the use of soap. Soap molecules have both polar and non-polar sections, therefore they allow non-polar compounds to dissolve in polar solvents such as water. With the use of soap, there are very few substances that won't dissolve in water. Note that even glass (or silicon dioxide) which is thought to be insoluble in water, actually does dissolve in water, but it does so extremely slowly. The most insoluble substance known to chemistry is Mercury sulfide. That absolutely does not dissolve in water (even with soap).

Powders like sugar, salt, baking soda, etc also dissolve.
