Does agar float in water?
Yes, low-density agar is used in most studies
1 answer
because it tends to float in water. Agar is a gelatinous substance derived from red algae, often used as a medium for growing bacterial colonies and as a stabilizer or thickener in various foods and products. The density of agar gels can be adjusted by altering the concentration of agar used to create the gel, with lower concentrations generally leading to a lighter, less dense gel that can float in water. However, it's important to note that the specific density of agar gels will depend on both the concentration of agar and the specific type of agar used, as well as any other substances that have been added to the gel.
