When water and oil mix, we get an emulsion (like lotion or soap). For this to happen, you will generally need an emulsifier, like emulsifying wax, borax + beeswax, solubilizer, or a high pH ingredient like sodium hydroxide. The first emulsions I made used borax and beeswax as the emulsifier. They required a 50/50 mix of oil and water, and were ...

It isn't 1+1=2. It's rather like 1+1=8,3543 or so. Chocolate mixes with water, milk, and coconut cream, and gives a homogenous liquid. But coconut oil doesn't mix with chocolate, and instead segregates and repeals, giving liquid chocolate with oil swimming on top. Yet, cacao butter and coconut oil mix together well, giving a homogenous liquid.

It will be worse, not better. What you are missing here is that cocoa powder does not dissolve at all, never, it just disperses in water (or milk). So there is no reason why methods for dissolving stuff would work with cocoa powder. You will need to use a method created for colloidproducing powders like cocoa powder, which is mostly starch ...

Answer: Solvents such as kerosene,water and cooking oil don't dissolve coal powder in them. hydrocarbons (petroleum, gasoline, gasoline, etc.) simply do not dissolve in water. This is because like dissolves like. Also, kerosene is lighter than water and floats on its surface rather than dissolving. That is why they are called immiscible liquids.

Benzene is an organic chemical compound with the molecular formula C 6 H benzene molecule is composed of six carbon atoms joined in a planar hexagonal ring with one hydrogen atom attached to each. Because it contains only carbon and hydrogen atoms, benzene is classed as a hydrocarbon.. Benzene is a natural constituent of petroleum and is one of the elementary petrochemicals.

Separation of sand from the mixture. The mixture left in the last step of sublimation is transferred into a beaker. Add 510 mL of distilled water into the mixture (water should be sufficient to dissolve the salt into it) and stir it with glass rod. Make a cone of filter paper as shown in the diagram.

Yes, pure honey dissolves in water. Honey is considered partially soluble in water, meaning it mixes with water to form a solution. When honey is added to water, it gradually dissolves due to its water content and solubility of its components. Honey forms a homogeneous mixture with water, resulting in a sweet, viscous solution.

Student 1. No, dissolved differently. Sugar can dissolve easier than salt because when you add 8 spoons of salt into water the salt already starts to stay in the bottom of the cup. And, when you add 30 spoons into water the sugar just starts to stay in the bottom of the cup. It's almost the same.

4. A lot of powders show this behaviour. Try it with flour or cocoa powder, and you get the same result. What all these powders have in common, is that the grains contain some hydrophobic material. When you put a bunch of powder in water, the outside layer of powder gets wet and sticks together, but doesn't let the water through, trapping ...

It can't wash away the bubble, because it is so viscous, it doesn't flow into the water. And the bubble protects the core of the clump from contact with water. This happens with starchy powders like flour, or also real cocoa powder. Tea powder is mostly dried cellulose, so it is also hard to dissolve. You mention cocoa as easily solved in water.

Pure red chilli powder does not really dissolve in water. This is, in fact, the best way to check for adulterants. If you find a white residue at the bottom of the glass which has a smooth feel, it could indicate the presence of soap stone. Chilli powder is mostly adulterated with brick powder, salt powder or talc powder.
