Generally when you're directed to add something slowly it's to avoid a runaway reaction. The effects vary; sometimes it's because of heat, other times it's for other reasons. I added hydrogen peroxide to a reaction once a little too quickly and got a snootful of ammonia that left me coughing for ten minutes.
Caffeine is more soluble in dichloromethane than in water due to differences in their polarity. When caffeine is added to the water-dichloromethane mixture, it is preferentially dissolved in dichloromethane, which is a non-polar solvent. This movement is driven by the principle "like dissolves like", where compounds tend to dissolve in solvents with similar polarity.
When magnesium ribbon is added to acetic acid, a chemical reaction occurs which produces hydrogen gas and magnesium acetate. The magnesium ribbon will dissolve as it reacts with the acetic acid, releasing bubbles of hydrogen gas in the process. This can be observed by the fizzing or bubbling that occurs.
Anhydrous sodium sulfate is a desiccant, meaning it has a strong affinity for water. When added to a dichloromethane solution, the anhydrous sodium sulfate will absorb any water present, effectively removing it from the solution by forming a hydrated salt. The water-free dichloromethane can then be decanted or filtered off for further use.
Acetic acid is added in the preparation of glucosazone to help maintain the acidic conditions needed for the reaction to occur. It also helps to stabilize the product and prevent decomposition. Additionally, acetic acid can act as a catalyst in the formation of glucosazone.
When zinc powder is added to acetic acid, a chemical reaction occurs in which zinc reacts with the acetic acid to produce zinc acetate and hydrogen gas. This reaction is represented by the equation: Zn + 2CH₃COOH → Zn(CH₃COO)₂ + H₂.
The formation of aspirin will proceed faster if acetic anhydride is used in place of acetic acid. However, acetic anhydride will hydrolyze in the presence of water to form acetic acid, slowing down the reaction.

Yes, acetic acid is highly soluble in water.
When universal indicator is added to acetic acid, it typically turns a shade of red, indicating that the solution is acidic. Acetic acid is a weak acid, so the color change may not be as intense as with stronger acids.
Vinegar (acetic acid solution) is essential; sometimes are added also spices, preservatives, etc.
Adding hydrogen peroxide slowly and with stirring helps to ensure uniform distribution within the milk, which is important for achieving the desired antimicrobial effect. Slow addition also helps prevent localized high concentrations of hydrogen peroxide which could have negative effects on the milk's composition or quality.
The red litmus paper will remain red in acetic acid. Acetic acid is a weak acid and does not change the color of red litmus paper.
When o-Phenylenediamine Dihydrochloride is added to acetic acid, it can undergo an acylation reaction to form the monoacetylated product, N-acetyl-o-Phenylenediamine. This reaction involves the substitution of a hydrogen atom on the nitrogen atom of the o-Phenylenediamine with an acetyl group from the acetic acid.
