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.
A high ankle sprain occurs when there is tearing and damage to the high ankle ligaments. These injuries are much less common than a traditional ankle sprain. What are the signs and symptoms of a high ankle sprain? A high ankle sprain occurs from a twisting or rotational injury. The high ankle sprain also can occur in the setting of an ankle fracture, which means the bones of the ankle are broken. In some cases, the ligament on the inside of the ankle, the deltoid, will be torn. In this event, the energy of the injury passes from the deltoid, through the high ankle ligaments, or syndesmosis, and up the leg through the fibula. This causes the fibula to be broken at a very high level.
