WhatsApp: +86 18037808511Even so, Caffeine is soluble in water to an extent as water can hydrogenate with caffeine molecules at six separate places. The water molecule's hydrogen is attracted to the highly electronegative oxygen and nitrogen atoms present in caffeine. Additionally, polar substances can dissolve together. Both water and caffeine are polar substances.

WhatsApp: +86 18037808511Cinnamon is slightly acidic, with a pH of around to When it is added to water, it can slightly lower the pH of the water, which can affect its solubility. If the water is too acidic, the solubility of cinnamon may decrease. On the other hand, if the water is too basic, the solubility of cinnamon may increase.
WhatsApp: +86 18037808511In general, it can be stated that cocoa products are not as dissolvable or soluble as coffee products. This is of course due to the extraction or filtration process by which coffee is prepared. Coffee merely exists of watersoluble substances, but cocoa is a mixture of water soluble components and insoluble small particles.

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.
WhatsApp: +86 18037808511It 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 ...
