1 Yellow media without gas pocket-sugar utilization with production of acid only. 2  Red media (no change in media) -no change and no sugar utilization. 3  Pink media especially at the top, ignore gas-no sugar utilization with degradation of protein resulting in alkaline end products (this may be difficult to see).
With organic solvents with long alkane chain, such as n-hexadecane and n-decane, the water droplets become much larger and the microemulsion is unstable. In this case, solvent polarity may have become a determining factor and the long alkane chain was too hydrophobic to form a stable microemulsion with water.
Xenon trioxide topic. Xenon trioxide is an unstable compound of xenon in its +6 oxidation state . It is a very powerful oxidizing agent , and liberates oxygen from water slowly (and xenon), accelerated by exposure to sunlight. It is dangerously explosive upon contact with organic materials. When it detonates, it releases xenon and oxygen gas. Chemistry Xenon trioxide is a strong oxidising agent and can oxidise most substances that are at all oxidisable. However, it is slow-acting and this reduces its usefulness. Above 25 Â°C, xenon trioxide is very prone to violent explosion: When it dissolves in water, an acidic solution of xenic acid is formed: This solution is stable at room temperature and lacks the explosive properties of xenon trioxide. It oxidises carboxylic acids quantitatively to carbon dioxide and water. [3]
