heterogeneous mixture
They dissolve faster in hot water.
Yes. Rock salt, which is largely the same as table salt, will dissolve in water.
In order to dissolve chalk in water, vinegar needs to be added. The vinegar has acid in it that eats away at the chalk to dissolve it.
Gasses dissolve in water because they bond to the water molecules. Gasses like hydrogen will bond with the oxygen in water to create H202 for example.
To dissolve flour in a liquid you will want to use a wisk. This will break apart the little bubbles and balls that flour forms when it is placed with a liquid like water or eggs.
Flour is made up of proteins and starches that do not easily dissolve in water. When flour is mixed with water, the proteins and starches form a sticky mixture due to the hydration of the proteins and the swelling of starch granules, rather than dissolving like a soluble substance.
Substances that dissolve in water are generally crystalline constructs of molecules that are pulled apart by the strong hydrogen bonding forces held by water. Flour is made from ground wheat, and as such cannot dissolve, as such.
Sugar will dissolve in water but flour won't. Mix both in water, strain out the flour. Evaporate the water and what is left is sugar.
It seems more like it absorbs water. The water gets thicker, pastier, the flour will gather at the bottom of the container if its still.
No. It will, however, create a slurry.
Cold water
No, flour won't dissolve it is insoluble it may look like it dissolves but it does not because if you left it for a few days it will sink to the bottom.
Flour is a solid substance composed of starch and proteins. Unlike sugar or salt, which are soluble in water, flour does not dissolve because its particles are too large and do not break down easily in water. Flour forms a suspension when mixed with water, creating a thick paste instead of dissolving completely.
salt dissolve faster because the baking soda went right to the bottom and the flour dissolved but it look like it did not dissolve because it went right to the bottom
No
To dissolve flour, gradually whisk it into a cold liquid until fully incorporated. For a smoother consistency, you can also mix flour with a small amount of butter or oil to create a roux before adding liquid. Heating the mixture can further dissolve the flour and create a thickening agent for sauces or soups.
