For litmus, it so happens that the 50 / 50 colour does occur at close to pH 7 - that's why litmus is commonly used to test for acids and alkalis. As you will see below, that isn't true for other indicators. Methyl orange. Methyl orange is one of the indicators commonly used in titrations. In an alkaline solution, methyl orange is yellow and the structure is: Now, you might think that when you add an acid, the hydrogen ion would be picked up by the negatively charged oxygen. That's the obvious place for it to go.
Ankle sprain: Types list. The list of types of Ankle sprain mentioned in various sources includes: 1  Anterior talofibular ligament sprain - most common. 2  Calcaneofibular ligament sprain - second most common.  Inversion injury - from the foot turning inward.
The most common type of ankle sprain is the stretching of the ligaments on the outside of the ankle. This type of sprain comprises of 85% of all ankle sprains. These are three ligaments; the anterior talofibular, posterior talofibular, and then calcaneofibular, that prevent the ankle from rolling in (inversion).igaments prevent abnormal movement and promote joint stability. There are ligaments surrounding the ankle to prevent it from rolling in or out. There are not, however, any ligaments to limit plantarflexion (bending the foot and toes away from you) as they are normal and necessary movements.
