Question

Aerozine 50 is made of 50 percent Hydrazine and 50 percent UDMH, but since they both make up one liquid fuel, how do they combine them to make a homogenous mixture? They both have different densities and are not bonded together to form Aerozine 50, so how is the mixture made to be perfectly mixed?

Answer 1

Hydrazine and UDMH are both organic nonpolar liquids. Despite having different densities, their miscibility with each other allows the mixture of the two to homogenize. This means that the concentration of hydrazine and UDMH in all parts of the mixture are the same. This is also the reason why the mixture is called Aerozine 50 because the components are not distinguished but rather, stay well mixed in the system providing a stable set of properties unique to Aerozine 50.
